The Polaris was[when?] 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.[citation needed]
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.[citation needed] 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.[citation needed]
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.[citation needed]
