Rolling Stock & Signalling

Keeping things on track

Circuit protection requirements for rail transportation and infrastructure go beyond the norm. Trains and signalling systems are exposed to widely varying temperatures and trains are subjected to considerable vibrations. Circuit protection solutions need to be practical, flexible, and work in all conditions.

Rolling Stock & Signalling is one of Emcomp's key segments. We provide reliable hydraulic-magnetic circuit breakers for rail transport and signalling systems. Our products are maintenance-free and their components are carefully selected to provide maximum life to the circuit protection. The hydraulic-magnetic design has a number of practical advantages and delivers better protection to the circuit, as well as more precise breaking.


Many contracts in Rolling stock & Signalling are awarded through procurement. Emcomp complies with the special requirements in the TransQ pre-qualification system and has been approved and qualified as a supplier.
