RTSA Qld Chapter Event (Webinar) – Train Brake Control on Long Downhill Track Gradients
May 28 @ 12:30 pm - 1:30 pm UTC+10
The handling of long heavy trains on track gradients is dependent on the performance of the brake and traction systems, and the train handling experience and route knowledge of the driver. The purpose of this presentation is to provide some understanding of the factors affecting the safe operation of heavy trains descending long track gradients.
Topics that will be discussed are:
- Train dynamics
- Brake fade
- Train handling operation known as “cycle braking”
- Equipment used to slow or retain brake cylinder pressure during the release of brakes
- The use of Independent brakes on both locomotives and on wagons with modified brake equipment
- Main reservoir air supply on wagons
- Electronically Controlled Pneumatic (ECP) brakes; and
- The application of park brakes for holding stationary
