The Polaris was a design of locomotive-hauled train designed in concept form by CSRE Ltd. The train was inspired by the British Rail InterCity 125 (HST) and was intended to have a top speed of 140 mph (225 km/h). The loco hauled trains would have had two power cars and been compatible with British Rail Mark 3 coaches. The power cars would have either been Diesel electric electric and electro-diesel making the design suitable for use across the whole British railway network.
