The New South Wales XPT (short for eXpress Passenger Train) is a class of diesel-powered passenger trains built by Comeng and ABB Transportation. Based on the British Rail designed Intercity 125 High Speed Train, each XPT set is made up of two XP Power Cars in a push-pull formation coupled to between four and seven carriages. The first sets entered service under the State Rail Authority in 1982 and now operate under NSW TrainLink, running on long-distance regional and interstate North Coast, Main Western and Main Southern lines throughout New South Wales and interstate into Victoria and Queensland.
