AeroLiner3000

The AeroLiner3000 is a project for the introduction of a double-decker train in the UK, which can run on a large part of the existing British rail network with the tight loading gauge PG1.

The train was developed by Andreas Vogler Studio together with the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt - DLR).

Andreas Vogler Studio (AVS) teamed up with the German Aerospace Center (DLR) to propose a high-capacity double-decker high-speed train to run at up to 400 km/h (250 mph) on the new High Speed 2 (HS2) high-speed line from London to Birmingham and be able to continue on the existing lines as far as Edinburgh.

Over the past two decades, double-decker cars have greatly helped to increase capacity for train operators, especially in Europe, but also worldwide.

Originally started as an experiment, British Railways did have the 'Bulleid Double Decker' car SR Class 4DD in operation for more than 20 years from 1949 to 1971.

As the compartments were alternately high and low, to ensure that the overall height of the unit was within the clearances necessary to pass through tunnels and under bridges, the 'Bulleid Double Decker' was more a split-level than a true double-decker.

The 4DD was somewhat unsuccessful because the upper level compartments were cramped and poorly ventilated (the upper-level windows could not be opened due to tight clearance).

In an emergency, the train applies additional eddy-current brakes at speeds between 250 km/h and 50 km/h to comply with the TSI High-Speed.

The end car front is designed with medium fineness ratio because it is assumed that in the future tunnel portals on high-speed lines will be constructed to cope with the train pressure head wave.

Furthermore, the weight savings will enable a double-decker car for GB PG1 gauge to be in line with the TSI-PRM standards and offer better seating comfort than many UK trains currently in operation.

The AeroLiner3000's design is optimised to achieve five minute dwell times at stations despite seating about 30% more passengers than a TGV Duplex.
