NGT LINK – High-Speed Intercity Trainset

The DLR is developing concepts to show the trends and technologies for future rail vehicles. The main goals of the Next Generation Train (NGT) project are shorter travel times and reductions in specific energy consumption, noise emissions, and wear, while increasing passenger safety and comfort and reducing life cycle costs. To achieve these goals, an operational concept with a family of high-speed trains was developed: The 400 km/h passenger train NGT HST, using the main high-speed lines, and the 230 km/h intercity train NGT LINK, to serve passengers from the surroundings.


The NGT LINK Electrical Multiple Unit


NGT LINK is a seven-car double-deck inter-regional train that connects smaller cities with each other and with the larger cities served by the long-distance train NGT HST. With its hybrid power system, NGT LINK can run on lines equipped for inductive power transfer, but also on conventionally electrified and partially electrified lines. NGT LINK achieves the goals of the NGT project through a combination of lightweight design, an innovative propulsion system, and a time- and energy-efficient operating strategy. Various measures enable a reduction of specific energy consumption of 50 % compared to its reference train, the ICE TD, and the passenger-flow optimised layout of the train facilitates short changeover times, ensuring reduced travel times.



The design of NGT LINK’s double-deck car bodies enable significant mass reductions through the use of lightweight materials and a force-flow optimised structure. While the ICE TD weighs 216 tonnes, NGT LINK, which is a full 13 metres longer, weighs only 215 tonnes yet seats 143 per cent more passengers (475 instead of 195).


The innovative mechatronic running gear that NGT LINK uses offers many advantages over conventional bogies. Because every wheel on the train is driven independently, there is no need for an axle within every wheelset. In a similar fashion to NGT HST, this allows stairless corridors on both levels over the entire length of the train, making NGT LINK a full double-decker. Additionally, driving each wheel enables regenerative braking at each wheel, resulting in large energy savings for a train with frequent stops.


The NGT LINK concept shows how trains of the future can be designed in order to offer a competitive, economical, and ecological transportation solution.
