New South Wales Endeavour railcar

The Endeavour railcars are a type of diesel multiple units (DMU) operated by Sydney Trains on intercity passenger rail services in New South Wales, Australia on the Hunter, Blue Mountains (to Bathurst), Southern Highlands and South Coast (to Bomaderry) lines. They are mechanically identical to the Xplorers, but are fitted out for shorter travel distances. All 30 carriages were built by ABB's Dandenong rolling stock factory.

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. Some Endeavours are scheduled to be replaced in 2026–2027 by the R sets.

The trains have multiple-unit capability with the Hunter J Set but only in the event of failure or for empty coaching stock movements. These cars normally operate as two-car sets, however during peak periods they can operate as four-car sets.
