The Xplorer is a class of diesel multiple unit trains built by ABB Transportation. Initially entering service in October 1993, the Xplorers are mechanically identical to the Endeavour Railcars, though feature a higher level of passenger amenity. All 23 carriages were built in Dandenong, Victoria. The Xplorers currently operate under NSW TrainLink, running on the regional Main North, Main Western and Main Southern lines throughout New South Wales.
