To ask Her Majesty's Government what are or will be the journey times between London and Edinburgh (calling at York and Newcastle) of (a) the proposed bi-mode super-express intercity train, (b) the existing high speed 125 mph diesel train, and (c) the existing C92 electric train with MK4 coaches.

No London to Edinburgh trains currently call at York and Newcastle only.

Typical fastest journey times of current services (Intercity 125s and Intercity 225s) London to Edinburgh are between four hours 20 minutes and four hours 30 minutes, with one train at four hours 13 minutes. There are usually three intermediate stops (eg Peterborough, York and Newcastle, or York, Newcastle and Berwick).

The indicative fastest super-express timetabled journey times are envisaged to be the same for both bi-mode and electric train types. This is four hours six minutes for services that call at four intermediate stations and four hours 11 minutes for services that call at five intermediate stations. It is planned to run all London-Edinburgh trains on these improved timings, not just the occasional headline train as is the case today.

Super-express trains will improve the journey times as well as frequency and reliability of services. The introduction of super-express trains enables significant timetable optimisations which will also result in a reduction in journey times of services provided by existing rolling stock.

The Class 92 locomotive was designed for use in the Channel Tunnel and is not used on UK intercity services.
