The Outback Xplorer is an Australian passenger train service operated by NSW TrainLink between Sydney and Broken Hill via the Main Western line.

It ceased in early 2000 due to the poor state of the passenger carriages, but resumed in May 2000 using Xplorer railcars.

[2] Unofficially known as the Outback Express, it was initially formed of 1940s vintage locomotive-hauled HUB/RUB carriages, usually hauled by a Clyde Engineering built 81 class locomotive.

[4] In May 2000, the service resumed with Xplorer railcars, operating as a set of three with carriage numbering A (first class and buffet car), B (economy) and D (economy with disability access seating area/toilet facilities).

Since the introduction of Xplorer railcars, the service runs to Broken Hill on Mondays, returning to Sydney on Tuesdays.
