For decades Unipart Rail has been producing the TCAID (Track Circuit Aid) to help to shunt signals in the leaf-fall season, but a new development has improved this incredibly useful technology to a whole new level of efficiency.
TCAID shunts the track circuit signal when railhead contamination creates a high impedance electrical conductivity path between the rail, wheel and axle interface. Or in layman's terms - leaves, snow and rust can stop the signal changing from green to red when a train passes.
Working with our TCA (Track Circuit Actuator), the TCAID detects the train and 'shunts' the signal as the train passes - ensuring that wrong side failures are eliminated, and keeping trains separated by the appropriate distance.
The new version, launched in June 2020, has been upgraded to deliver these benefits:
-
detects a TCA signal from a train at less than 200 metres away
-
nearly 50% more efficient
-
half the power consumption
-
100 times more reliable
Commenting on the development process, our customer in Network Rail Sussex said:
“The speed at which the Unipart Rail engineers picked up the issues and developed the new product was excellent. Communication and updates were very good and the attention to detail was also very good."
