How to stop a speeding train

How to stop a speeding train
After doubts about the future of the UK’s high-speed rail link HS2, the government has said the project will go ahead, although delayed by up to three years, in 2029. The prospect of 250mph rail travel is again real and, while the brakes have been put on HS2 for now, OEMs and engineers should consider how the trains will function safety. That includes their braking systems.

Avoiding shocks when electrifying rail

Avoiding shocks when electrifying rail
The political wind has been blowing towards complete rail electrification for decades now without significant progress, so it’s clearly not a straightforward problem to tackle. If it’s to be done, it needs be done right. Here, Steve Hughes, Managing Director of power quality specialist REO UK, explains the importance of ensuring the components underpinning electric trains are carefully considered.

Keeping trains moving; meeting new technology demands

Keeping trains moving; meeting new technology demands
A key element of the propulsion system for low speed urban transportation to high speed intercity trains is the traction converter that transforms the power from the power source, whether a catenary or diesel engine, to drive the electric motors.  By Michel Ghilardi, LEM Research & Development Senior Engineer
