The Chips is the legacy name for the passenger train that operates over the Blue Mountains between Lithgow and Sydney.
As of 2023, the name is unofficial and over the years, has not formally been used to refer to the Blue Mountains Line service run by NSW TrainLink.
The name has been applied to various Blue Mountains services over the years and today is a commuter service from Lithgow to Sydney operated by V sets.
Following electrification of the Main Western line in 1958, it was operated by U set single-deck electric trains. These in turn were replaced by double-deck V sets.
It is complemented by another service, The Fish.
According to the current timetable, The Fish leaves Lithgow at 5:08am, reaches Mt Victoria at 5:37am and arrives Sydney at 7:47am. The Chips leaves Lithgow at 5:38am, reaches Mt Victoria at 6:07am and arrives Sydney at 8:17am.
