The Endeavour Railcars are a class of diesel multiple units operated by NSW TrainLink on passenger rail services in New South Wales, Australia on the Hunter, Blue Mountains (to Bathurst), Southern Highlands and South Coast lines (between Kiama and Bomaderry). They are mechanically identical to the Xplorers. All 30 carriages were built by ABB Transportation in Dandenong, Victoria. Fourteen two-carriage sets were ordered in April 1992 to replace Class 620/720 railcars, DEB set railcars and locomotive hauled stock, with the first entering service in March 1994. In November 1994, one further two-carriage set was ordered. All are scheduled to be replaced in the early 2020s by the NSW TrainLink Regional Train Project. Features Each set consists of two carriages, one having a wheelchair-accessible toilet (TE), and the other having luggage space and bicycles racks (LE). All cars are air-conditioned. They operate as four carriage sets on a few peak hour services. Each car is powered by a Cummins KTA-19R diesel engine rated at at 1800rpm coupled to a Voith T311r hydraulic transmission driving both axles on one bogie via Voith Turbo V15/19 final drives. The transmission incorporates a Voith KB260/r hydrodynamic brake. An auxiliary Cummins LT10R(G) diesel engine drives a Newage Stamford UCI274F alternator to supply power for the air conditioning and lighting. The maximum speed of Endeavour railcars is but in service this is limited to .
