Transport for London (TfL) has revealed the interior design of its new Crossrail trains with features such as intelligent lighting and temperature control systems.
The new trains, designed by Barber & Osgerby and UK train manufacturer Bombardier, will be made up of nine carriages, measure just over 200 metres long, and be capable of carrying up to 1,500 passengers.
TfL said the interior design and colour palette has been selected to provide an "accessible and welcoming" environment for passengers when the service begins in 2017.
The design includes darker floors and natural finish materials, while light coloured ceilings aim to maximise the feeling of height and openness. The material and colour choices also align with Crossrail stations for a consistent customer experience.
Seating will be a mixture of metro-style and bay seats and free wi-fi will be available on the trains as well as on the platforms and people will have access to 4G.
There will be four dedicated wheelchair spaces on each train and a number of multi-use spaces available where seating can be tipped up to accommodate prams or luggage.
Edward Barber and Jay Osgerby, design advisors for the Crossrail train, said: "We are pleased to be working as design advisors on the new Crossrail fleet. This is an exciting civic project and a key component of London's transportation future for the next one hundred years. We are honoured to be making a contribution to its design and look forward to its inaugural journey."
The trains will have walk-through carriages, each with three wide doorways to enable people to get on and off quickly at central stations, air-conditioning and use the latest technology to provide customers with real-time travel information to help them plan their onward journeys.
When fully operational in 2019, Crossrail trains will serve Reading and Heathrow in the west through to Shenfield and Abbey Wood in the east, passing through new tunnels under central London.
