Automatic Train Protection


Project overview

Transport for NSW is boosting safety across the electrified rail network by delivering new Automatic Train Protection (ATP) technology.

ATP will provide additional safety benefits and more reliable services by ensuring trains operate within the permitted speed limit.

Key benefits

The system is being installed on train fleets and across our electrified rail network.

This includes:

  • installation of balises (electronic transponders) in the rail corridor between existing trackside infrastructure to monitor train speeds
  • installation of equipment on board all suburban  and Intercity train fleets that will continually collect information such as the train's speed, distance and direction.

ATP is being rolled out across the Sydney Trains and NSW TrainLink electrified network including the South Coast Line as far as Kiama, the Blue Mountains Line to Lithgow, and the Central Coast / Newcastle Line.
