WTB (Wired Train Bus) Cables

FRL-WTB-02YCH-2G0.75/FRL-WTB-02YCH-1P0.75S/FRL-WTB-02YCH-2P0.75S

Rolling Stock Cables

A. Conductor B. Insulation C. Screen D. Sheath

The cables are designed for permanent installation inside of rolling stock to connect fixed parts. A typical

application is a communication system in a locomotive. The system uses a wire backed bus system to the TCN

standard for control and instrumentation and for diagnostics. This bus system consists of the rail bus WTB

(Wired Train Bus) and the road bus MVB (Multifunction Vehicle Bus) which are connected via redundant

gateways.
