Performance Through Engagement

Track Circuit Assistor (TCA®)

Temperature Control Unit (TCU)

Improves Track Shunting when rails are contaminated with rust. The build-up of rust on rails can prevent the track circuit being activated when a train passes. This problem is overcome with the TCA® fitted to DMUs.

The Temperature Control Unit (TCU) system is designed to control the Heating Ventilation and Air Conditioning (HVAC) system of a rail vehicle and provide real time condition information on the current state of the HVAC operation.

Assisted Lift Trunnion

HD Assisted Lift Trunnion

To increase worker safety and reduce installation time, Unipart Dorman has developed a new assisted lift trunnion (ALT) which uses progressive rate spring technology to reduce the lifting force required as the post is moved from the horizontal to the vertical plane.

The HD ALT uses a double spring configuration to deliver the same lifting force characteristics as the original ALT but enabling it to be used with heavier, more complex head types and taller posts.
