London Underground has shown off a concept train that could start appearing on the tube network in around 10 years time.

The “New Tube for London” will be introduced first on the Piccadilly line, followed by the Bakerloo, Central and Waterloo & City lines. It also includes air-cooling for the first time on the deep level tube network.


The train – designs for which are part of a new public exhibition at King’s Cross St Pancras Underground station – also features improved accessibility, with step free access from the platform as well as walk-through carriages and wider doors.

Wider doors are a key feature as the speed up how fast people can get on/off the trains at stations. Shorter times waiting at stations means faster journeys, which also translates into more carrying capacity for the tube line.

  • Central line 25% (equivalent of up to 12,000 customers per hour);
  • Bakerloo line by 25% (equivalent of up to 8,000 customers per hour);
  • Waterloo & City line by 50% (equivalent of up to 9,000 customers per hour);
  • Piccadilly line by 60% (equivalent of up to 19,000 customers per hour).


As I recently reported, the trains will also be designed for fully automatic operation — although that would not be expected to come into effect until the late 2030s at the earliest.

A formal Invitation to tender is expected to be issued early next year and a contract to build the new trains to be awarded in 2016. The first train is expected to come into service on the Piccadilly line in 2022.

The Piccadilly line currently serves 210 million customers a year and demand is expected to grow 20% by 2020. The Piccadilly line has therefore been prioritised as the first of the four lines to benefit from the new trains and signalling system.


The cost of the proposed 250 new trains varies between £1.0 billion and £2.5 billion.

The New Tube for London programme will see approximately:

  • 100 trains for the Piccadilly line;
  • 100 trains for the Central line
  • 40 trains for the Bakerloo line
  • 10 trains for the Waterloo & City line.

The New Tube for London exhibition is at King’s Cross St Pancras Underground station, Northern ticket hall, from Thursday 9 October until Sunday 16 November.

    boring and dull

    Does Waterloo and City really need 10 trains? That seems an excessive number for a service that has 2 stops on it. Wouldn’t it be cheaper to reconfigure the Waterloo end so that trains don’t have to go into the siding to turn around?

    I was thinking that about the Waterloo & City too, and checked to see how many seem to be running. Have to check at rush hour to see if there’s ever more than two.

    With walk-through carriages it’d be cool to be the only person on board and see the train snaking end-to-end. (Or being the only passenger on board until they go driverless!)

    Seems to be missing out the grab handles of the S class trains

    I shall be at King’s Cross tomorrow on my way to Ally Pally and will try and remember to go and take a look.

    I like the walkthrough trains as it means you don’t have to keep getting off at stations and running up to the part of the train you would have entered in the first place.

    Very disappointed. I passed through King’s Cross this evening, but could not see any signs to the exhibit. It was too late for me to going wondering about, so I shall probably never see this.

    Very nice, I hope I get to see them.
