First look at Derby-made HS2 train interiors

The interior of future HS2 train carriages - which will be made in Derby - have been unveiled for the first time.

HS2 Ltd has revealed test designs for its high-speed trains, including what it hopes will become the most comfortable seats on any UK rail service.

Standard class seats will have what the firm calls "market-leading" leg room of 87cm, according to full-size concepts at train manufacturer Alstom's factory in Litchurch Lane.

HS2 Ltd senior rolling stock engineer James Dawson said the ambition is for services to have "the most comfortable seat on trains in the UK".

Airline-style seats will give each passenger easy access to a large fold-down table, a shelf for small electronic devices, a reading light with three brightness settings, a coat hook, a USB-C socket and two three-pin plug sockets, the latest version shows.

The bottom part of HS2 seats will be able to slide forwards, enabling passengers to recline without encroaching on the space of the person behind them.

Passengers travelling on some existing trains run by operators such as Thameslink and Great Western Railway have complained that thin padding makes the seats uncomfortable for long journeys, comparing them to ironing boards.

Mr Dawson added: "We know there have been issues with some recent seats, we know the failure, we know why that is.

"We'll start off by looking at what's in the cushion to make sure that's comfortable and robust, and look at the geometry of the back.

"We've taken all of the feedback from all the user groups, and we've made - and will be making in the future - design tweaks to reflect that feedback."

The process of designing HS2 carriages began in 2022 following the awarding of a £1.9 billion contract to an Alstom-Hitachi joint venture to design, build and maintain 54 high-speed trains at three different locations in England.

The shells at Hitachi’s Newton Aycliffe site, the wheels and axles - known as bogies - at Alstom’s facility in Crewe and the final assembly - including the interior at its historic Derby factory.

Consultations have been conducted with more than 100 people with a range of needs, including parents with young children, cyclists and wheelchair users, leading to the creation of mock-ups of train carriage sections.

Further testing will lead to more tweaks before a final design is created in early 2026.

Onboard toilets will have a number of features aimed at solving problems suffered by passengers on many existing services.

A shelf will enable users to store a bag, preventing it from coming into contact with a wet floor.

Information screens will display how many minutes before the train reaches the next station, and a pull-down seat will be available to keep toddlers restrained while their parents use the toilet.

In the main carriage sections, the glass used for overhead luggage racks will be frosted.

This is a result of privacy concerns on some existing trains, where unfrosted glass can reflect electronic device screens, making them visible to other passengers.

HS2 trains will offer bookable spaces for bicycles, wheelchairs and unfolded pushchairs, level boarding at HS2 stations, and have larger-than-normal head room due to more equipment being stored under floors and at the ends of carriages.
