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).[1][2] The loco hauled trains would have had two power cars and been compatible with British Rail Mark 3 coaches.[2] The power cars would have either been Diesel electric, electric and electro-diesel,[2] making the design suitable for use across the whole British railway network. CSRE also proposed an Electric multiple unit (EMU) type of Polaris called the Polaris E.[3]
The Polaris concept will now not be taken to market.
Potential orders
According to the Managing Director of CSRE, David Shipley, there was interest from a number of train operating companies, and the Polaris were planned to be operating in the UK by 2012. This will now be no longer happening. Grand Central Railway planned to introduce some Polaris trains in 2010, but did not announce an order; presently it operates a mixture of British Rail Class 43 power cars with British Rail Mark 3 coaches and British Rail Class 180 multiple units.
Alliance Rail Holdings, an open access operator, aimed to use 17 Polaris trainsets on a number of services starting in late 2013, although the deal was not finalised.
