74-783: The V/Line VLocity , sometimes called the VLocity 160 , is a diesel multiple unit train built by Bombardier Transportation and later Alstom in Dandenong for V/Line , the regional rail operator in the Australian state of Victoria . Continuously in production since 2003, the VLocity is the highest-speed train in the V/Line fleet, with a top speed of 160 km/h (99 mph). As of November 2024 with set 125 entering service, 124 3-car sets are in revenue service, one collision damaged set
148-499: A diesel engine drives an electrical generator or an alternator which produces electrical energy . The generated current is then fed to electric traction motors on the wheels or bogies in the same way as a conventional diesel–electric locomotive . On some DEMUs, such as the Bombardier Voyager , each car is entirely self-contained and has its own engine, generator and electric motors. In other designs, such as
222-543: A VLocity set failed to activate boom gates at the Progress Street level crossing in Dandenong . This led Metro Trains to ban all sets from operating on suburban lines until the issue had been resolved. The combined restrictions on the VLocity fleet led to the daily cancellation of nearly 70 V/Line services from mid-January. By the beginning of March, Bombardier had increased its capacity to remachine affected wheels, and track identified as potentially contributing to
296-628: 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

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,
4662-425: The project as a means of allowing V/Line services to access Platforms 1-8 at Southern Cross without needing to use Metropolitan tracks, as the root cause of the increase in wheel wear, and suggested that the relatively stiff suspension of the VLocity was the reason it had been most severely affected. The New Generation Rollingstock ordered for Queensland Rail from Bombardier, although built in India, are based on

These 125 mph (201 km/h) trains run with a streamlined power car at each end and (typically) seven to nine intermediate trailer cars. Although originally classified as DEMUs, the trailer cars are very similar to loco-hauled stock, and
5032-538: The wheel wear situation had been reprofiled; as a consequence, VLocity units were gradually returned to service. In April, a report by the Institute of Railway Technology at Monash University identified tight curves and an inadequate track lubrication on the newly opened Regional Rail Link , particularly along the North Melbourne Flyover near North Melbourne Station, which was upgraded as part of
5106-633: Was 700 HP and had three or six coaches, made first by ICF. Transmission was Voith-hydraulic. Max speed 100 km/h. Second generation DMU: Rated power is 1400 HP and have eight coaches. Max speed is 105 km/h. Transmission is DC electric. Made at ICF and RCF . Third generation DMU: Rated power is 1,600 HP and have ten coaches. Max speed is 110 km/h. Transmission is AC electric. Made at ICF . State-owned company PT.INKA builds several type of DMU, some of which operate in urban and suburban areas. In Japan, where gasoline-driven railbuses (on small private lines) and railmotors ( Kihani 5000 of
5180-542: Was announced that 2 of 3 daily Bairnsdale trains would be taken over by VLocity sets. In May 2018, the Rail Tram and Bus Union (RTBU) announced that it had received confirmation that a buffet facility would be included in new intermediate carriages, added to existing sets to form 4-car trains for long-distance services. In April 2020, designs for standard gauge VLocity sets, to be used on the Albury line , were released by
5254-541: Was completed in July 2004, and testing began shortly after. The trains were tested at 160 km/h (99 mph) for the first time on 17 September, when Premier Steve Bracks joined a test run along a 30 km (19 mi) route from Warragul to Moe . Safety improvements were suggested at various stages in the development of the VLocity and, following the Waterfall accident in New South Wales, in which
5328-641: Was for the 29 sets to be fitted with 2+3 seating, for a total capacity of 173 passengers per two-carriage set. However, in February 2003, that was changed to 144 seats in a 2+2 formation. In 2003, it was announced that the units would be built in Bombardier's Dandenong factory, with the bogies to be constructed at Bombardier's Derby Litchurch Lane Works in England, and the control system to be supplied by Bombardier's plant in Västerås , Sweden. The first unit
5402-748: Was introduced on 3 September, despite allegations by the State Opposition of ongoing issues with the TPWS. In addition, the Ararat and Echuca services are operated by VLocitys. From 2010, one Ballarat line service each day was extended to Maryborough . In 2005, the VLocity received an Australian Design Award , the first rail vehicle to do so, as well as an accolade from Engineers Australia . On 10 November 2008, seven-carriage-long VLocity trains (2 x 2-carriage + 1 x 3-carriage sets) commenced regular operation on peak-hour Geelong line services. Previously,
5476-575: Was one of the first adopters of diesel multiple unit trains in Asia. Initially built as gasoline-powered railmotors, the locally assembled Manila Railroad RMC class of 1929 was the first to be powered by diesel traction. Some units were also converted to streamliner units by 1932 for first-class services on the South Main Line between Manila and Legazpi, Albay . Since then, generations of DMUs were used chiefly for short-distance commuter services by
