105-474: Catch Me Who Can was the fourth and last steam railway locomotive created by the inventor and mining engineer Richard Trevithick . It was an evolution of three earlier locomotives which had been built for Coalbrookdale , Penydarren ironworks and Wylam colliery. Demonstration runs began in July 1808, and Catch Me Who Can was the first locomotive in the world to haul fare-paying passengers. Catch Me Who Can
210-659: A Scottish inventor, built a small-scale prototype of a steam road locomotive in Birmingham . A full-scale rail steam locomotive was proposed by William Reynolds around 1787. An early working model of a steam rail locomotive was designed and constructed by steamboat pioneer John Fitch in the US during 1794. Some sources claim Fitch's model was operable already by the 1780s and that he demonstrated his locomotive to George Washington . His steam locomotive used interior bladed wheels guided by rails or tracks. The model still exists at
315-660: A (newly identified) Killingworth Billy in 1816. He also constructed The Duke in 1817 for the Kilmarnock and Troon Railway , which was the first steam locomotive to work in Scotland. In 1825, Stephenson built Locomotion No. 1 for the Stockton and Darlington Railway , north-east England, which was the first public steam railway in the world. In 1829, his son Robert built in Newcastle The Rocket , which
420-448: A balance has to be struck between obtaining sufficient draught for combustion whilst giving the exhaust gases and particles sufficient time to be consumed. In the past, a strong draught could lift the fire off the grate, or cause the ejection of unburnt particles of fuel, dirt and pollution for which steam locomotives had an unenviable reputation. Moreover, the pumping action of the exhaust has the counter-effect of exerting back pressure on
525-486: A crankpin on the driving wheel ( Main driver in the US) or to a crank on a driving axle. The movement of the valves in the steam chest is controlled through a set of rods and linkages called the valve gear , actuated from the driving axle or from the crankpin; the valve gear includes devices that allow reversing the engine, adjusting valve travel and the timing of the admission and exhaust events. The cut-off point determines
630-520: A cylinder. Despite the failure it was purchased by the L&;MR, where it ran for two years before being leased to the Bolton and Leigh Railway . The last locomotive to drop out was Novelty which used advanced technology for 1829 and was lighter and considerably faster than the other locomotives in the competition. It was the crowd favourite and reached a then-astonishing 28 miles per hour (45 km/h) on
735-402: A deployable "water scoop" fitted under the tender or the rear water tank in the case of a large tank engine; the fireman remotely lowered the scoop into the trough, the speed of the engine forced the water up into the tank, and the scoop was raised again once it was full. Water is essential for the operation of a steam locomotive. As Swengel argued: Rainhill Trials The Rainhill trials
840-429: A gauge mounted in the cab. Steam pressure can be released manually by the driver or fireman. If the pressure reaches the boiler's design working limit, a safety valve opens automatically to reduce the pressure and avoid a catastrophic accident. The exhaust steam from the engine cylinders shoots out of a nozzle pointing up the chimney in the smokebox. The steam entrains or drags the smokebox gases with it which maintains
945-488: A lower pressure in the smokebox than that under the firebox grate. This pressure difference causes air to flow up through the coal bed and keeps the fire burning. The search for thermal efficiency greater than that of a typical fire-tube boiler led engineers, such as Nigel Gresley , to consider the water-tube boiler . Although he tested the concept on the LNER Class W1 , the difficulties during development exceeded
1050-433: A lower reciprocating mass than three, four, five or six coupled axles. They were thus able to turn at very high speeds due to the lower reciprocating mass. A trailing axle was able to support a huge firebox, hence most locomotives with the wheel arrangement of 4-4-2 (American Type Atlantic) were called free steamers and were able to maintain steam pressure regardless of throttle setting. The chassis, or locomotive frame ,
1155-426: A means of increasing revenue. Catch Me Who Can became the world’s first locomotive to haul fare-paying passengers. Some claimed that performance of the locomotive was inferior to that of a horse over a 24 hour endurance test. Trevithick claimed that Catch Me Who Can could travel over 240 miles (390 km) in that time. The locomotive was reported to have reached a top speed of 12 miles per hour (19 km/h) on
SECTION 10
#17327697617091260-556: A much more reliable locomotive than the others. Novelty almost matched it in terms of efficiency, but its firebox design caused it to gradually slow to a halt due to a buildup of molten ash (called "clinker") cutting off the air supply. The restaged trials were run over the Llangollen Railway , Wales , and were the subject of a 2003 BBC Timewatch documentary. This restaging should not be taken as accurate as there were major compromises made for television and because of
1365-639: A number of Swiss steam shunting locomotives were modified to use electrically heated boilers, consuming around 480 kW of power collected from an overhead line with a pantograph . These locomotives were significantly less efficient than electric ones ; they were used because Switzerland was suffering a coal shortage because of the War, but had access to plentiful hydroelectricity . A number of tourist lines and heritage locomotives in Switzerland, Argentina and Australia have used light diesel-type oil. Water
1470-461: A number of important innovations that included using high-pressure steam which reduced the weight of the engine and increased its efficiency. Trevithick visited the Newcastle area in 1804 and had a ready audience of colliery (coal mine) owners and engineers. The visit was so successful that the colliery railways in north-east England became the leading centre for experimentation and development of
1575-459: A rigid frame with a 30% weight reduction. Generally, the largest locomotives are permanently coupled to a tender that carries the water and fuel. Often, locomotives working shorter distances do not have a tender and carry the fuel in a bunker, with the water carried in tanks placed next to the boiler. The tanks can be in various configurations, including two tanks alongside ( side tanks or pannier tanks ), one on top ( saddle tank ) or one between
1680-401: A tank in the locomotive tender or wrapped around the boiler in the case of a tank locomotive . Periodic stops are required to refill the tanks; an alternative was a scoop installed under the tender that collected water as the train passed over a track pan located between the rails. While the locomotive is producing steam, the amount of water in the boiler is constantly monitored by looking at
1785-440: A top speed of 30 miles per hour (48 km/h)) hauling 13 tons, and was declared the winner of the £500 prize (equal to £55,577 today). The Stephensons were given the contract to produce locomotives for the L&MR. The Times carried a full report of the trials on 12 October 1829 from which the following extract are taken: THURSDAY – THIRD DAY: Mr. Stephenson's engine, "The Rocket," weighing 4 tons 3 cwt., performed, to-day,
1890-609: A variation of the Large Logo Rail Blue livery where the BR logo was replaced by Rocket 150 motif on a yellow background. In a 2002 restaging of the Rainhill trials using replica engines, neither Sans Pareil (11 out of 20 runs) nor Novelty (10 out of 20 runs) completed the course. In calculating the speeds and fuel efficiencies, it was found that Rocket would still have won, as its relatively modern technology made it
1995-514: Is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in
2100-475: Is crucial to the efficiency of any steam locomotive, and the internal profiles of the chimney (or, strictly speaking, the ejector ) require careful design and adjustment. This has been the object of intensive studies by a number of engineers (and often ignored by others, sometimes with catastrophic consequences). The fact that the draught depends on the exhaust pressure means that power delivery and power generation are automatically self-adjusting. Among other things,
2205-419: Is directed upwards out of the locomotive through the chimney, by way of a nozzle called a blastpipe , creating the familiar "chuffing" sound of the steam locomotive. The blastpipe is placed at a strategic point inside the smokebox that is at the same time traversed by the combustion gases drawn through the boiler and grate by the action of the steam blast. The combining of the two streams, steam and exhaust gases,

The boiler is rigidly mounted on a "saddle" beneath the smokebox and in front of the boiler barrel, but the firebox at the rear is allowed to slide forward and backwards, to allow for expansion when hot. European locomotives usually use "plate frames", where two vertical flat plates form
2415-924: The Drache , was delivered in 1848. The first steam locomotives operating in Italy were the Bayard and the Vesuvio , running on the Napoli-Portici line, in the Kingdom of the Two Sicilies. The first railway line over Swiss territory was the Strasbourg – Basel line opened in 1844. Three years later, in 1847, the first fully Swiss railway line, the Spanisch Brötli Bahn , from Zürich to Baden
2520-591: The Ohio Historical Society Museum in Columbus, US. The authenticity and date of this locomotive is disputed by some experts and a workable steam train would have to await the invention of the high-pressure steam engine by Richard Trevithick , who pioneered the use of steam locomotives. The first full-scale working railway steam locomotive was the 3 ft ( 914 mm ) gauge Coalbrookdale Locomotive built by Trevithick in 1802. It
2625-612: The Pennsylvania Railroad class S1 achieved speeds upwards of 150 mph, though this was never officially proven. In the United States, larger loading gauges allowed the development of very large, heavy locomotives such as the Union Pacific Big Boy , which weighs 540 long tons (550 t ; 600 short tons ) and has a tractive effort of 135,375 pounds-force (602,180 newtons). Beginning in

2835-535: The United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevithick built the first steam locomotive known to have hauled a load over a distance at Pen-y-darren in 1804, although he produced an earlier locomotive for trial at Coalbrookdale in 1802. Salamanca , built in 1812 by Matthew Murray for the Middleton Railway ,
2940-463: The Centre for Transport Studies. A circular track 100 feet (30 m) in diameter was built, on which a locomotive and a small number of carriages would run. Members of the public could view and ride on this train for a fare of 1 shilling . Trevithick hoped this would be a commercial venture, as well as creating publicity and hopefully demand for more locomotives. Trevithick's fourth railway locomotive
3045-483: The Engine shall perform each trip shall be one mile and three quarters (2.8 km) each way, including one-eighth of a mile (200 m) at each end for getting up the speed and for stopping the train; by this means the Engine, with its load, will travel one and a-half mile (2.4 km) each way at full speed." "The Engines shall make ten trips, which will be equal to a journey of 35 miles (56 km); thirty miles (48 km) whereof shall be performed at full speed, and

"The Engine, with the carriages attached to it, shall be run by hand up to the Starting Post, and as soon as the steam is got up to fifty pounds per square inch (3.4 bar), the engine shall set out upon its journey." "The distance
3255-484: The L&MR that ran past Rainhill village was straight and level for over 1 mile (1.6 km), and was chosen as the site for the trials. The locomotives were to run at Kenrick's Cross, on the mile east from the Manchester side of Rainhill Bridge. Two or three locomotives ran each day, and several tests for each locomotive were performed over the course of six days. Between 10,000 and 15,000 people turned up to watch

As the line was then not electrified, the Advanced Passenger Train was also pushed, but by the latest diesel, Class 56 , 077. The 'Grand Cavalcade' on each of the three days featured up to 40 steam and diesel locomotives and other examples of modern traction, including: Two Class 86 locomotives 86214 Sans Pareil and 86235 Novelty were painted in

On 7 December 1835, the Adler ran for the first time between Nuremberg and Fürth on the Bavarian Ludwig Railway . It was the 118th engine from the locomotive works of Robert Stephenson and stood under patent protection. In Russia , the first steam locomotive

John Steven's "steam wagon" which was demonstrated on a loop of track in Hoboken, New Jersey in 1825. Many of the earliest locomotives for commercial use on American railroads were imported from Great Britain, including first the Stourbridge Lion and later the John Bull . However, a domestic locomotive-manufacturing industry

In May 1980 the Rocket 150 celebration was held to mark the 150th Anniversary of the opening of the Liverpool and Manchester Railway and the trials the year before. A replica of Novelty was built for
3885-550: The adhesive weight. Equalising beams connecting the ends of leaf springs have often been deemed a complication in Britain, however, locomotives fitted with the beams have usually been less prone to loss of traction due to wheel-slip. Suspension using equalizing levers between driving axles, and between driving axles and trucks, was standard practice on North American locomotives to maintain even wheel loads when operating on uneven track. Locomotives with total adhesion, where all of

So astonishing was the celerity with which the engine, without its apparatus, darted past the spectators, that it could be compared to nothing hut the rapidity with which the swallow darts through the air. Their astonishment was complete, every one exclaiming involuntarily, "The power of steam". After the Rainhill trials Rocket was tested on

Three times its own weight having been attached to the engine, the machine commenced its task, and performed it at the rate of 16 miles in the hour. Mr. Stephenson's engine, the Rocket, also exhibited today. Its tender was completely detached from it, and the engine alone shot along the road at

"As soon as the Engine has performed this task, (which will be equal to the travelling from Liverpool to Manchester,) there shall be a fresh supply of fuel and water delivered to her; and, as soon as she can be got ready to set out again, she shall go up to the Starting Post, and make ten trips more, which will be equal to
4305-402: The boiler materials to the point where it needs to be rebuilt or replaced. Start-up on a large engine may take hours of preliminary heating of the boiler water before sufficient steam is available. Although the boiler is typically placed horizontally, for locomotives designed to work in locations with steep slopes it may be more appropriate to consider a vertical boiler or one mounted such that

4410-404: The boiler remains horizontal but the wheels are inclined to suit the slope of the rails. The steam generated in the boiler fills the space above the water in the partially filled boiler. Its maximum working pressure is limited by spring-loaded safety valves. It is then collected either in a perforated tube fitted above the water level or by a dome that often houses the regulator valve, or throttle,

This is another area where the gas transfers heat to the water and is called the firebox heating surface. Ash and char collect in the smokebox as the gas gets drawn up the chimney ( stack or smokestack in the US) by the exhaust steam from the cylinders. The pressure in the boiler has to be monitored using

At the same time, BR agreed to put a team of staff into the sidings at Bold to "straighten" the bent rails. Both activities were achieved on time and
4725-400: The circular track and Trevithick was of the opinion that it was capable of 20 miles per hour (32 km/h) on straight track. Operation of Catch Me Who was hindered by the soft ground that the track was laid on. Trial runs began around 24 July 1808, but almost immediately the ground under the track sank, causing the iron rails to break as the 8-ton locomotive passed over them. Trevithick had
4830-689: The dominant fuel worldwide in steam locomotives. Railways serving sugar cane farming operations burned bagasse , a byproduct of sugar refining. In the US, the ready availability and low price of oil made it a popular steam locomotive fuel after 1900 for the southwestern railroads, particularly the Southern Pacific. In the Australian state of Victoria, many steam locomotives were converted to heavy oil firing after World War II. German, Russian, Australian and British railways experimented with using coal dust to fire locomotives. During World War 2,
4935-440: The early 1900s, steam locomotives were gradually superseded by electric and diesel locomotives , with railways fully converting to electric and diesel power beginning in the late 1930s. The majority of steam locomotives were retired from regular service by the 1980s, although several continue to run on tourist and heritage lines. The earliest railways employed horses to draw carts along rail tracks . In 1784, William Murdoch ,

Steam locomotive A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam . It is fuelled by burning combustible material (usually coal , oil or, rarely, wood ) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it

The Rocket, to the dismay of the many visitors, failed to run. It came off the rails as it was exiting the Bold Colliery sidings and buckled the rim of one of its large drive wheels. That evening, senior staff from a St Helens road transport company met a former colleague of

The water in the boiler shall be cold, and there shall be no fuel in the fireplace. As much fuel shall be weighed, and as much water shall be measured and delivered into
SECTION 50
#17327697617095460-448: The firebox becomes exposed. Without water on top of the sheet to transfer away the heat of combustion , it softens and fails, letting high-pressure steam into the firebox and the cab. The development of the fusible plug , a temperature-sensitive device, ensured a controlled venting of steam into the firebox to warn the fireman to add water. Scale builds up in the boiler and prevents adequate heat transfer, and corrosion eventually degrades
5565-418: The first day of competition. It later suffered damage to a boiler pipe which could not be fixed properly on site. Nevertheless, it ran the next day and reached 15 miles per hour (24 km/h) before the repaired pipe failed and damaged the engine severely enough that it had to be withdrawn. The Rocket was the only locomotive that completed the trials. It averaged 12 miles per hour (19 km/h) and achieved
5670-512: The frames ( well tank ). The fuel used depended on what was economically available to the railway. In the UK and other parts of Europe, plentiful supplies of coal made this the obvious choice from the earliest days of the steam engine. Until 1870, the majority of locomotives in the United States burned wood, but as the Eastern forests were cleared, coal gradually became more widely used until it became
5775-418: The grate into an ashpan. If oil is used as the fuel, a door is needed for adjusting the air flow, maintaining the firebox, and cleaning the oil jets. The fire-tube boiler has internal tubes connecting the firebox to the smokebox through which the combustion gases flow transferring heat to the water. All the tubes together provide a large contact area, called the tube heating surface, between the gas and water in
5880-582: The highly mineralised water was available, and locomotive boilers were lasting less than a quarter of the time normally expected. In the days of steam locomotion, about half the total train load was water for the engine. The line's operator, Commonwealth Railways , was an early adopter of the diesel-electric locomotive . The fire-tube boiler was standard practice for steam locomotive. Although other types of boiler were evaluated they were not widely used, except for some 1,000 locomotives in Hungary which used

A replica is under construction by the Trevithick 200 charity at the Severn Valley Railway workshops, close to the site where the original locomotive was built. As of July 2017 work towards completion of the engine continues with the braking mechanism being the only major item left to complete. The replica engine can be seen outside near to
6195-515: The late 1700s and early 1800s, the inventor and mining engineer Richard Trevithick was the primary developer of the steam locomotive . He wanted to present his new invention to the general public, and he looked for a suitable site to demonstrate his invention. He chose Bloomsbury , directly south of the Euston Road , near London 's Euston Square . The site is believed to be under University College London ’s Chadwick Building, which now houses
6300-681: The locomotive ran on a circular track in the factory yard. It was the first locomotive to be built on the European mainland and the first steam-powered passenger service; curious onlookers could ride in the attached coaches for a fee. It is portrayed on a New Year's badge for the Royal Foundry dated 1816. Another locomotive was built using the same system in 1817. They were to be used on pit railways in Königshütte and in Luisenthal on
6405-423: The locomotive reached a reported speed of between 12 miles per hour (19 km/h) and 15 miles per hour (24 km/h). The circus closed following a derailment caused by one of the rails breaking underneath the locomotive. While the advantages and applications of steam locomotives had been demonstrated, the venture was a financial failure that played a significant part in Trevithick's bankruptcy in 1809. During

When inside cylinders are mounted between the frames, the plate frames are a single large casting that forms a major support element. The axleboxes slide up and down to give some sprung suspension, against thickened webs attached to the frame, called "hornblocks". American practice for many years
6615-509: The mainframes. Locomotives with multiple coupled-wheels on a rigid chassis would have unacceptable flange forces on tight curves giving excessive flange and rail wear, track spreading and wheel climb derailments. One solution was to remove or thin the flanges on an axle. More common was to give axles end-play and use lateral motion control with spring or inclined-plane gravity devices. Railroads generally preferred locomotives with fewer axles, to reduce maintenance costs. The number of axles required

The remainder of the stroke is driven by the expansive force of the steam. Careful use of cut-off provides economical use of steam and in turn, reduces fuel and water consumption. The reversing lever ( Johnson bar in

The first railway service outside the United Kingdom and North America was opened in 1829 in France between Saint-Etienne and Lyon ; it was initially limited to animal traction and converted to steam traction early 1831, using Seguin locomotives . The first steam locomotive in service in Europe outside of France
6930-468: The piston in turn. In a two-cylinder locomotive, one cylinder is located on each side of the vehicle. The cranks are set 90° out of phase. During a full rotation of the driving wheel, steam provides four power strokes; each cylinder receives two injections of steam per revolution. The first stroke is to the front of the piston and the second stroke to the rear of the piston; hence two working strokes. Consequently, two deliveries of steam onto each piston face in

In 2008, the curator of the National Museum of Science and Industry , John Liffen, announced that the most widely-known depiction of Catch Me Who Can and the Bloomsbury demonstration track was likely a twentieth century forgery. Other depictions based on this influential work were in turn misleading. There are few reliable illustrations of the locomotive. Even before this,

The steam then either travels directly along and down a steam pipe to the engine unit or may first pass into the wet header of a superheater , the role of the latter being to improve thermal efficiency and eliminate water droplets suspended in the "saturated steam", the state in which it leaves the boiler. On leaving the superheater,
7245-559: The railway fixed, and it closed. In the long term, the Steam Circus was not a fruitless venture. Trevithick had become the first person to successfully prove that a steam locomotive on iron rails was feasible. It would be another 20 years before Trevithick’s concept was fully realised at the Rainhill Trials of 1829, at which the pioneering railway engineers George Stephenson and Robert Stephenson successfully demonstrated
7350-400: The railway using cables . They had appointed George Stephenson as their engineer of the line in 1826, and he strongly advocated for the use of steam locomotives instead. As the railway was approaching completion, the directors decided to hold a competition to decide whether locomotives could be used to pull the trains; these became the Rainhill trials. A prize of £500 (equal to £55,577 today)

Designing the exhaust ejector became a specific science, with engineers such as Chapelon , Giesl and Porta making large improvements in thermal efficiency and a significant reduction in maintenance time and pollution. A similar system was used by some early gasoline/kerosene tractor manufacturers ( Advance-Rumely / Hart-Parr ) –
7560-504: The steam exits the dry header of the superheater and passes down a steam pipe, entering the steam chests adjacent to the cylinders of a reciprocating engine. Inside each steam chest is a sliding valve that distributes the steam via ports that connect the steam chest to the ends of the cylinder space. The role of the valves is twofold: admission of each fresh dose of steam, and exhaust of the used steam once it has done its work. The cylinders are double-acting, with steam admitted to each side of
7665-477: The steam locomotive. Trevithick continued his own steam propulsion experiments through another trio of locomotives, concluding with the Catch Me Who Can in 1808, first in the world to haul fare-paying passengers. In 1812, Matthew Murray 's successful twin-cylinder rack locomotive Salamanca first ran on the edge-railed rack-and-pinion Middleton Railway . Another well-known early locomotive
7770-544: The success of Rocket at the 1829 Rainhill Trials had proved that steam locomotives could perform such duties. Robert Stephenson and Company was the pre-eminent builder of steam locomotives in the first decades of steam for railways in the United Kingdom, the United States, and much of Europe. Towards the end of the steam era, a longstanding British emphasis on speed culminated in a record, still unbroken, of 126 miles per hour (203 kilometres per hour) by LNER Class A4 4468 Mallard , however there are long-standing claims that

Within two months of its original opening, the locomotive again derailed. By then, fewer people were paying the shilling fare. Trevithick had spent all of his savings on setting up the Steam Circus, and he could not pay to have
7980-434: The track, is of paramount importance. Because reciprocating power has to be directly applied to the rail from 0 rpm upwards, this creates the problem of adhesion of the driving wheels to the smooth rail surface. Adhesive weight is the portion of the locomotive's weight bearing on the driving wheels. This is made more effective if a pair of driving wheels is able to make the most of its axle load, i.e. its individual share of
8085-410: The trials and bands provided musical entertainment on both days. Cycloped was the first to drop out of the competition. It used a horse walking on a drive belt for power and was withdrawn after an accident caused the horse to burst through the floor of the engine. The next locomotive to retire was Perseverance , which was damaged in transit to the competition. Burstall spent the first five days of
8190-479: The trials repairing his locomotive, and though it ran on the sixth day, it failed to reach the required 10 miles per hour (16 km/h) speed and was withdrawn from the trial. It was granted a £25 consolation prize (equal to £2,779 today). Sans Pareil nearly completed the trials, though at first there was some doubt as to whether it would be allowed to compete as it was 300 pounds (140 kg) overweight. However, it did eventually complete eight trips before cracking
8295-433: The two cylinders generates a full revolution of the driving wheel. Each piston is attached to the driving axle on each side by a connecting rod, and the driving wheels are connected together by coupling rods to transmit power from the main driver to the other wheels. Note that at the two " dead centres ", when the connecting rod is on the same axis as the crankpin on the driving wheel, the connecting rod applies no torque to
8400-419: The water level in a transparent tube, or sight glass. Efficient and safe operation of the boiler requires keeping the level in between lines marked on the sight glass. If the water level is too high, steam production falls, efficiency is lost and water is carried out with the steam into the cylinders, possibly causing mechanical damage. More seriously, if the water level gets too low, the crown sheet (top sheet) of
8505-401: The water-tube Brotan boiler . A boiler consists of a firebox where the fuel is burned, a barrel where water is turned into steam, and a smokebox which is kept at a slightly lower pressure than outside the firebox. Solid fuel, such as wood, coal or coke, is thrown into the firebox through a door by a fireman , onto a set of grates which hold the fuel in a bed as it burns. Ash falls through
8610-408: The wheel. Therefore, if both cranksets could be at "dead centre" at the same time, and the wheels should happen to stop in this position, the locomotive could not start moving. Therefore, the crankpins are attached to the wheels at a 90° angle to each other, so only one side can be at dead centre at a time. Each piston transmits power through a crosshead , connecting rod ( Main rod in the US) and
8715-411: The wheels are coupled together, generally lack stability at speed. To counter this, locomotives often fit unpowered carrying wheels mounted on two-wheeled trucks or four-wheeled bogies centred by springs/inverted rockers/geared rollers that help to guide the locomotive through curves. These usually take on weight – of the cylinders at the front or the firebox at the rear – when the width exceeds that of
8820-406: The will to increase efficiency by that route. The steam generated in the boiler not only moves the locomotive, but is also used to operate other devices such as the whistle, the air compressor for the brakes, the pump for replenishing the water in the boiler and the passenger car heating system. The constant demand for steam requires a periodic replacement of water in the boiler. The water is kept in
8925-436: The work required by the original conditions. The following is a correct account of the performance: The engine, with its complement of water, weighed 4 tons 5 cwt., and the load attached to it was 12 tons 15 cwt., and, with a few persons who rode, made it about 13 tons. The Journey was 1.21 mile each way, with an additional length of 220 yards at each end to stop the engine in, making in one Journey 3[?] miles. The first experiment
9030-878: The world also runs in Austria: the GKB 671 built in 1860, has never been taken out of service, and is still used for special excursions. In 1838, the third steam locomotive to be built in Germany, the Saxonia , was manufactured by the Maschinenbaufirma Übigau near Dresden , built by Prof. Johann Andreas Schubert . The first independently designed locomotive in Germany was the Beuth , built by August Borsig in 1841. The first locomotive produced by Henschel-Werke in Kassel ,
9135-562: Was Puffing Billy , built 1813–14 by engineer William Hedley . It was intended to work on the Wylam Colliery near Newcastle upon Tyne. This locomotive is the oldest preserved, and is on static display at the Science Museum, London . George Stephenson , a former miner working as an engine-wright at Killingworth Colliery , developed up to sixteen Killingworth locomotives , including Blücher in 1814, another in 1815, and
9240-471: Was Trevithick's return-flue type, complete with an internal firebox . The locomotive was similar to an engine that Trevithick had built in 1803 to power a dredger for use on the Thames . In spite of his goal of introducing steam locomotion to the public, Trevithick built a high wooden fence around the demonstration track, concealing it from view to all but those who paid to enter. This may have been done as
9345-491: Was an important competition run from the 6 to 14 October 1829, to test George Stephenson 's argument that locomotives would have the best motive power for the then nearly-completed Liverpool and Manchester Railway (L&MR). Ten locomotives were entered, of which five were able to compete, running along a 1 mile (1.6 km) length of level track at Rainhill , in Lancashire (now Merseyside ). Stephenson's Rocket
9450-644: Was built in 1834 by Cherepanovs , however, it suffered from the lack of coal in the area and was replaced with horse traction after all the woods nearby had been cut down. The first Russian Tsarskoye Selo steam railway started in 1837 with locomotives purchased from Robert Stephenson and Company . In 1837, the first steam railway started in Austria on the Emperor Ferdinand Northern Railway between Vienna-Floridsdorf and Deutsch-Wagram . The oldest continually working steam engine in
9555-436: Was built new for the Steam Circus. It was named Catch Me Who Can by the sister of Davies Gilbert . This new locomotive differed from the previous locomotive designs: instead of a horizontal cylinder, flywheel, and geared drive, Catch Me Who Can used a vertical cylinder encased in the boiler , driving one pair of wheels directly. The cylinder was 14.5 inches (37 cm) in diameter, with a 4 feet (1.2 m) stroke. The boiler
9660-608: Was constructed during 1808 by the engineers John Urpeth Rastrick and John Hazledine at their foundry in Bridgnorth , England . It was demonstrated to the public at Trevithick's "Steam Circus", a circular track in Bloomsbury , just south of the present-day Euston Square tube station , in London . Members of the public could pay to ride in carriages pulled by Catch Me Who Can around this track. During these demonstration runs,
9765-760: Was constructed for the Coalbrookdale ironworks in Shropshire in the United Kingdom though no record of it working there has survived. On 21 February 1804, the first recorded steam-hauled railway journey took place as another of Trevithick's locomotives hauled a train along the 4 ft 4 in ( 1,321 mm )-wide tramway from the Pen-y-darren ironworks, near Merthyr Tydfil , to Abercynon in South Wales. Accompanied by Andrew Vivian , it ran with mixed success. The design incorporated
9870-411: Was dictated by the maximum axle loading of the railroad in question. A builder would typically add axles until the maximum weight on any one axle was acceptable to the railroad's maximum axle loading. A locomotive with a wheel arrangement of two lead axles, two drive axles, and one trailing axle was a high-speed machine. Two lead axles were necessary to have good tracking at high speeds. Two drive axles had
9975-423: Was entered in and won the Rainhill Trials . This success led to the company emerging as the pre-eminent builder of steam locomotives used on railways in the UK, US and much of Europe. The Liverpool and Manchester Railway opened a year later making exclusive use of steam power for passenger and goods trains . Before the arrival of British imports, some domestic steam locomotive prototypes were built and tested in
10080-471: Was from 14 to 17 miles an hour; and had the whole distance been in one continuing direction, there is no doubt but the result would have been 16 miles an hour. The consumption of coke was very moderate, not exceeding half a ton in the whole 70 miles. At several parts of the journey the engine moved at 18 miles an hour. SATURDAY – FIFTH DAY: In the expectation of witnessing the Novelty perform its appointed task,
10185-709: Was named The Elephant , which on 5 May 1835 hauled a train on the first line in Belgium, linking Mechelen and Brussels. In Germany, the first working steam locomotive was a rack-and-pinion engine, similar to the Salamanca , designed by the British locomotive pioneer John Blenkinsop . Built in June 1816 by Johann Friedrich Krigar in the Royal Berlin Iron Foundry ( Königliche Eisengießerei zu Berlin),
10290-443: Was of 35 miles, which is exactly ten journeys, and, including all the stoppages at the ends, was performed in 3 hours and 10 minutes, being upwards of 11 miles an hour. After this a fresh supply of water was taken in, which occupied 16 minutes, when the engine again started, and ran 35 miles in 2 hours and 52 minutes, which is upwards of 12 miles an hour, including all stoppages. The speed of the engine, with its load when in full motion,
10395-443: Was offered to the winner of the trials. Three notable engineers were selected as judges: John Urpeth Rastrick , a locomotive engineer of Stourbridge , Nicholas Wood , a mining engineer from Killingworth with considerable locomotive design experience, and John Kennedy , a Manchester cotton spinner and a major proponent of the railway. The L&MR company set the rules for the trials. The rules went through several revisions;
10500-534: Was opened. The arid nature of south Australia posed distinctive challenges to their early steam locomotion network. The high concentration of magnesium chloride in the well water ( bore water ) used in locomotive boilers on the Trans-Australian Railway caused serious and expensive maintenance problems. At no point along its route does the line cross a permanent freshwater watercourse, so bore water had to be relied on. No inexpensive treatment for
10605-577: Was soon established. In 1830, the Baltimore and Ohio Railroad 's Tom Thumb , designed by Peter Cooper , was the first commercial US-built locomotive to run in America; it was intended as a demonstration of the potential of steam traction rather than as a revenue-earning locomotive. The DeWitt Clinton , built in 1831 for the Mohawk and Hudson Railroad , was a notable early locomotive. As of 2021 ,
10710-403: Was supplied at stopping places and locomotive depots from a dedicated water tower connected to water cranes or gantries. In the UK, the US and France, water troughs ( track pans in the US) were provided on some main lines to allow locomotives to replenish their water supply without stopping, from rainwater or snowmelt that filled the trough due to inclement weather. This was achieved by using
10815-488: Was the first commercially successful steam locomotive. Locomotion No. 1 , built by George Stephenson and his son Robert's company Robert Stephenson and Company , was the first steam locomotive to haul passengers on a public railway, the Stockton and Darlington Railway , in 1825. Rapid development ensued; in 1830 George Stephenson opened the first public inter-city railway, the Liverpool and Manchester Railway , after
10920-409: Was the only locomotive to complete the trials, and was declared the winner. The directors of the L&MR accepted that locomotives should operate services on their new line, and George and Robert Stephenson were given the contract to produce locomotives for the railway. The directors of the Liverpool and Manchester Railway had originally intended to use stationary steam engines to haul trains along
11025-404: Was to use built-up bar frames, with the smokebox saddle/cylinder structure and drag beam integrated therein. In the 1920s, with the introduction of "superpower", the cast-steel locomotive bed became the norm, incorporating frames, spring hangers, motion brackets, smokebox saddle and cylinder blocks into a single complex, sturdy but heavy casting. A SNCF design study using welded tubular frames gave
