Alstom Transport has developed a new train for the U.K. from its X’Trapolis product platform, and incorporating technology used in the company’s very high-speed trains.
The train features bogie offset articulation, which reduces the number of bogies by up to 30 percent, allowing the carriage to be shorter and wider, optimizing the vehicle gauge. A wide, uninterrupted aisle and spacious gangways are created throughout the train, improving the feeling of security and mobility for passengers.
The door configuration is geared to reduce stopping times at stations by making the boarding and alighting process more efficient, particularly on high-density routes. Two sets of double doors are situated in the center of each carriage, providing 25 percent more doors than a conventional trainset per equivalent length. The shorter carriages of X’Trapolis are also closer to platform edges, especially when these are curved, reducing the stepping distance from train to platform by almost half.
Passenger information systems help the passenger make informed decisions, with exterior displays indicating the capacity status of each carriage to facilitate boarding and interior displays providing updates on connecting services at stations.
The X’Trapolis is also 95 percent recyclable. Due to the reduced number of bogies, it is also 28 percent lighter than existing electric commuter trains on the U.K. network, and creates less noise both externally and internally.
