Could uncomfortable stifling and stinky tube journeys be a thing of the past with the next generation of state-of-the-art Tube trains?
The Inspiro train, unveiled by Siemens today costs £1m per carriage and compared to the current rolling stock on the London underground it is lighter, brighter more spacious and weighs a third less.
All the carriages are also air conditioned, and like the new generation of London Underground trains, they dispense with doors linking carriages.
The new trains could also feature electronic passenger information boards and electronic ticketing.
The prototype train will be on show to mark the 150th anniversary of the London Underground at the Crystal exhibition centre in the Royal Victoria Docks.
In a big hint to Boris Johnson Siemens suggested that the next generation of trains could be made in London if he placed an order for one of the new trains for the Piccadilly, Bakerloo and Central lines.
Transport for London has secured its Government funding for the tube based on the claim that it could give orders to British firms, the Evening Standard reported.
