Rail & Transit.
Traction power engineering for high-speed, metro and urban rail — built around traction load behaviour, harmonics, stray current and the interference traction supply creates.
Project location, local requirements and any site support are confirmed for the agreed scope.

Rail and metro electrification, traction supply and the interference it creates.
Service selection follows your asset, your appointment and your Project Stage. Every scope line below links to the one Service page that delivers it.
How the Sector Works.
The chain from supply to load, and where engineering decisions matter most.
What Drives Decisions Here.
The pressures our Clients in Rail & Transit work under, and design for.
Safety
Earthing, stray current and protection protect people and assets along the line.
Grid Impact
Traction loads unbalance and distort the utility supply.
Programme
Energisation dates are fixed to the opening of the line.
Reliability
Service frequency depends on traction supply staying up.
