68-707: The Dyserth branch line was a short standard-gauge mineral railway between the northern end of the Clwydian Range at Dyserth and the North Wales Coast Line at Prestatyn . The line was constructed by the London and North Western Railway in 1869; it was built to carry quarried stone and coal. The rise of tourism led to the introduction of a passenger service in 1905. There were stations at Dyserth and Meliden, and basic halts were built at other stopping places. Competition from road transport led to
136-790: A Stadler FLIRT fleet, with 20 trains DEMU version. Germany has employed DMUs for both commuter and express services for many decades. The SVT 877 Fliegender Hamburger DMU, introduced in 1933, made the run from Berlin to Hamburg in an astonishing 138 minutes, and its derivative SVT 137 broke the land speed record in 1936. After World War 2, the VT 11.5 DMU was the flagship of the glamorous Trans Europ Express . Since 1968, DB has designated DMUs with class numbers beginning in 6. While DB and regional transport authorities generally prefer electric power for commuter rail, many local and rural lines remain un-electrified, and DMUs are invaluable in providing services to those areas. DMUs in service as of 2021 include
204-628: A WDM-2 or WDM-3A locomotive in the middle. These old trains had the loco controls duplicated in the Driving Trailer coach and all the actuation information reaching the locomotive through thin communication lines. This was called 'push-pull train'. The longest running such push-pull service operated between Diva – Bhiwandi Road and Vasai Road and was recently converted into an MEMU train service in 2018. India's first and largest DMU shed at Jalandhar , Punjab, holds more than 90 units placed in service all over Punjab. First generation DMU: Rated power

The result was the adoption throughout a large part of the world of a "standard gauge" of 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ), allowing interconnectivity and interoperability. A popular legend that has circulated since at least 1937 traces the origin of the 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) gauge even further back than

As railways developed and expanded, one of the key issues was the track gauge (the distance, or width, between the inner sides of the rails) to be used. Different railways used different gauges, and where rails of different gauge met – a " gauge break " – loads had to be unloaded from one set of rail cars and reloaded onto another,

The extra half inch was not regarded at first as very significant, and some early trains ran on both gauges daily without compromising safety. The success of this project led to Stephenson and his son Robert being employed to engineer several other larger railway projects. Thus the 4 ft 8 + 1 ⁄ 2 in ( 1,435 mm ) gauge became widespread and dominant in Britain. Robert

It allowed the broad-gauge companies in Great Britain to continue with their tracks and expand their networks within the "Limits of Deviation" and the exceptions defined in the Act. After an intervening period of mixed-gauge operation (tracks were laid with three rails), the Great Western Railway finally completed the conversion of its network to standard gauge in 1892. In North East England, some early lines in colliery ( coal mining ) areas were 4 ft 8 in ( 1,422 mm ), while in Scotland some early lines were 4 ft 6 in ( 1,372 mm ). The British gauges converged starting from 1846 as

The Royal Commission made no comment about small lines narrower than standard gauge (to be called "narrow gauge"), such as the Ffestiniog Railway . Thus it permitted a future multiplicity of narrow gauges in the UK. It also made no comments about future gauges in British colonies, which allowed various gauges to be adopted across

2856-429: The initial gauge of 4 ft 8 in ( 1,422 mm ) was set to accommodate the existing gauge of hundreds of horse-drawn chaldron wagons that were already in use on the wagonways in the mines. The railway used this gauge for 15 years before a change was made, debuting around 1850, to the 1,435 mm ( 4 ft 8 + 1 ⁄ 2 in ) gauge. The historic Mount Washington Cog Railway ,

2992-402: The line climbed southwards on a significant gradient, with the steepest stretch at 1 in 45. The sharpest curve had a radius of 11 chains (220 m). These factors combined to necessitate ruling speed limits of 20 mph for trains climbing to Dyserth and 25 mph back to the main line. These limits were lowered to 15 mph over level crossings and 10 mph approaching the junction with

As goods and mineral traffic on the line declined, the branch was closed to general traffic on 1 December 1951, while coal continued to be hauled as the only ordinary traffic; that too ceased on 4 May 1964. A revival in limestone quarrying at Dyserth resulted in continuation of

#17327870553833536-642: The passenger service being withdrawn in 1930. With the eventual demise of all the mineral industries around Dyserth the entire line was closed in September 1973. The area between Dyserth and Cwm (about 2km to the south of Dyserth) was the site of lead and haematite mining, as well as numerous limekilns . These heavy industries shipped their ore to the River Clwyd for coastal shipping, but this soon became disadvantageous compared to other mines and quarries with rail connections. An initial proposal in 1860

By the early 1980s, many of the surviving First Generation units were reaching the end of their design life, leading to spiralling maintenance costs, poor reliability and a poor public image for the railway. A stopgap solution was to convert some services back to locomotive haulage, as spare locomotives and hauled coaching stock were available, but this also increased operating costs. Commencing in
3672-588: The present, several types of DMUs operate in Slovakia. Was the most common type in Slovakia is a Class 812 ZSSK based on the ČD Class 810 . These are used almost exclusively for hauling passenger trains on non-electrified regional lines and these trains often excel in low travel speeds. In the past, however, in Slovakia there were a number of express trains driven by motor coaches , which often overcame heavier trains driven by steam locomotives at cruising speed, and classic sets. A typical example can be, for example,

The line was steeply graded and had sharp curves. The branch, originally known as the Prestatyn and Cwm Line, opened to goods and mineral traffic on 1 September 1869. Shortly afterwards an intermediate goods station at Meliden
3808-436: The rails is better, thus the minimum distance between the wheels (and, by extension, the inside faces of the rail heads ) was the important one. A standard gauge for horse railways never existed, but rough groupings were used; in the north of England none was less than 4 ft ( 1,219 mm ). Wylam colliery's system, built before 1763, was 5 ft ( 1,524 mm ), as was John Blenkinsop 's Middleton Railway ;
3876-411: The rest of the network. All other railways use 1,668 mm ( 5 ft 5 + 21 ⁄ 32 in ) ( broad gauge ) and/or 1,000 mm ( 3 ft 3 + 3 ⁄ 8 in ) metre gauge .

A DMU requires no separate locomotive , as the engines are incorporated into one or more of the carriages. Diesel-powered single-unit railcars are also generally classed as DMUs. Diesel-powered units may be further classified by their transmission type: diesel–mechanical DMMU , diesel–hydraulic DHMU , or diesel–electric DEMU . The diesel engine may be located above
4012-492: The term "narrow gauge" for gauges less than standard did not arise for many years, until the first such locomotive-hauled passenger railway, the Ffestiniog Railway , was built. In 1845, in the United Kingdom of Great Britain and Ireland , a Royal Commission on Railway Gauges reported in favour of a standard gauge. The subsequent Gauge Act ruled that new passenger-carrying railways in Great Britain should be built to

Research, however, has been undertaken to support the hypothesis that "the origin of the standard gauge of the railway might result from an interval of wheel ruts of prehistoric ancient carriages". In addition, while road-travelling vehicles are typically measured from the outermost portions of the wheel rims, it became apparent that for vehicles travelling on rails, having main wheel flanges that fit inside
