The Long Test Track (LTT) is 1500 metres long and consists of two parallel, narrow gauge, lengths of precisely aligned railway track. It is fully instrumented to enable complex photographic and telemetry data systems to comprehensively monitor trials.
Other tracks include the Short Test Track (STT) at just over 200 metres long and another general purpose track consisting of a 400-metre, standard British Rail track that terminates at a solid concrete butt.
