Loughborough University’s breakthrough railway technology on track for prototype development

Breakthrough railway technology masterminded by Loughborough University engineers has entered into the next stage of development with industry backing.
Repoint is a robust and reliable points concept which breaks with 200 years of tradition to offer a change in design that will increase reliability, reduce maintenance costs and boost capacity on the railways.
It is the result of research carried out with industry experts into improved switches which eradicate known issues with existing designs.
The two-and-a-half-year project, funded by the UK rail safety body RSSB (formerly known as the Rail Safety and Standards Board), will see a full scale, prototype track switch developed and deployed.
Using safety concepts derived from aerospace and the nuclear industries, Repoint allows redundant, fail-safe actuation and locking of track switches for the first time. This means that a failure of a single actuator element will not cause the failure of the entire switch – allowing trains to continue until such a time as maintenance becomes feasible.
With increasing traffic density throughout the network, windows for maintenance work are becoming tighter, which is why the Repoint technology - which will be developed alongside RSSB, London Underground, and its supply base - has so much potential.
Repoint has been led by Professor Roger Dixon, Senior Project Engineer Sam Bemment, Professor Roger Goodall, and Dr Chris Ward. The team are part of the Control Systems Research Group in the University’s Wolfson School of Mechanical, Electrical and Manufacturing Engineering.
