The New South Wales XPT (short for eXpress Passenger Train) is a class of diesel-powered passenger trains built by Comeng and ABB. Based on the British Rail-designed High Speed Train, each XPT set comprises two XP power cars in a push-pull configuration and, between them, between four and seven passenger carriages.^[1]

The XPT was procured following a competitive tendering process under an initial contract for 30 trainsets, comprising 10 power cars and 20 carriages, in March 1980. The design of the InterCity 125 was substantially modified. Testing commenced in August 1981 and the first set entered service under the State Rail Authority during January 1982. The XPT proved to be considerably faster than existing rolling stock, reducing the journey time between Sydney and Melbourne by up to two hours.

Throughout the 1980s, additional XPT sets were procured, permitting the launch of services such as the Northern Tablelands XPT and the Riverina XPT. An XPT fare surcharge was discontinued in May 1985. During the early 1990s, sleeping cars were procured, permitting the XPT to effectively take on overnight services such as the Sydney/Melbourne Express. There were also advanced plans made for additional XPTs to be produced for Thailand, but these were later abandoned. The XPTs are presently operated under NSW TrainLink, running on long-distance regional and interstate North Coast, Main Western and Main Southern line services throughout New South Wales and interstate into Victoria and Queensland.

The trains have been subject to refurbishments and overhauls to permit their use into the twenty-first century. During October 2016, the NSW government announced the XPT fleet would be entirely replaced as part of the Regional Train Project. The replacement fleet, originally set to enter service in 2023, has encountered delays (now scheduled for around 2025–2027), thus the XPT will operate longer than originally anticipated with the potential for them to be retained after the new trains enter service.
