On 18 March, Richard Branson and Brian Souter attended the press unveiling of a Virgin Trains East Coast Hitachi IEP train (branded ‘Azuma’) at Kings Cross station.

[Richard Branson, 18 March 2016]

We’ll be adding 65 Virgin Azuma trains to our fleet from 2018, providing an extra 12,200 seats to services on a new and improved timetable. What’s more, the Azumas have the potential to reach speeds of 140mph (subject to Network Rail delivering on the track), meaning our passengers will get to their destinations much quicker.

However, the costs and benefits of increasing East Coast linespeed to 225 km/h remain unclear. The works required might include track and overhead line alterations, new signalling, and level crossing closures. Network Rail has decided not to go ahead with a “single programme of level crossing closures” on the route between Doncaster and London.

The future use of the non-tilting IEP trains for the East Coast franchise was imposed by the Department for Transport. Whatever the shortcomings of the design, the IEP does at least demonstrate the capacity achievable with longer carriages. For example, a 234-metre nine-car Azuma has more seats (~627) than a 265-metre eleven-car Pendolino (589).

A ten-car (260-metre) IEP would seat around 715 passengers, so if such units were used on the West Coast Main Line, there could be a capacity uplift of 20%, without needing to lengthen any platforms or run more trains.

Virgin Trains West Coast, Liverpool / Manchester - London timetable pattern, Dec 2015. The regular services make three intermediate stops (MK, Stoke, Stockport; Stoke, Macclesfield, Stockport; and Crewe, Wilmslow, Stockport)

On the London Euston — Manchester Piccadilly run, a 12-car IEP (312 metres) could provide up to 900 seats, but would require new or lengthened platforms at the small number of stations used by the service. The cost would be a tiny fraction of the sum required for building HS2.

  1. ICE capacity of 627 is 101 First + 526 Second (16.1% first). 11 car Pendolino has 145 First and 444 Second (24.6% first). source Wikipedia. How much of the extra capacity comes from longer coaches as opposed to reduction in first class percentage and reduced legroom? A tilting Pendolino should be able to exploit its 225kph capability far more than an IEP and the extra llength of 26m coaches could create operational problems on many lines.
