The AeroLiner3000 is a project for the introduction of a double-decker train in Great Britain that can run on a large part of the existing British routes with the tight PG1 clearance gauge. The train was developed by Andreas Vogler Studio together with the German Aerospace Center DLR. A 9 m long 1: 1 demonstrator was presented at the InnoTrans 2016 in Berlin .
Starting position
In 2014, the innovation program of the British RSSB announced a competition under the motto "Tomorrow's Train Design Today", the goals of which include the creation of a rail vehicle concept to increase route capacity, reduce CO 2 emissions and increase passenger comfort as well as are cost-effective innovative ideas for passenger transport. Andreas Vogler Studio has teamed up with the German Aerospace Center (DLR) in order to combine his design skills with the findings from the “ Next Generation Train ” (NGT) research project . Andreas Vogler Studio is one of the three main prize winners of the innovation competition, all of whom have worked on different projects.
concept
Over the past two decades, double-deck vehicles have made a major contribution to increasing transport capacities, especially for European rail operators, but also worldwide. However, due to its narrow clearance profile, Great Britain was severely restricted in its implementation, which is why double-decker trains were not considered. Nonetheless, Great Britain had the “Bulleid Double Decker” SR Class 4DD in operation for over 20 years, from 1949 to 1971. The compartments were arranged alternately high and low to ensure that the overall height was within the clearance heights of tunnels and bridges. It was therefore more a question of coaches with staggered levels than true double-deck coaches with two levels one above the other.
The presented version of the AeroLiner3000 is a double-decker, high-speed railcar passenger train that is compatible with the HS2 Classic Compatible Train Specifications 2012.
The multiple unit is 201 m long with 21 m long end cars and 17 m long intermediate cars, each with four individually driven and controlled wheels at the ends of the car, which form an innovative virtual Jakobs bogie. The axle loads are 17 t. Each car has two toilets and six disabled spaces on the lower level. Depending on the allocation of space, a half-train can accommodate a minimum of 627 and a maximum of 700 seats. In comparison, a TGV Duplex has 510 seats.
A half train of the double-decker AeroLiner3000 electric multiple unit consists of two end cars and nine intermediate cars. The carriages have single wheel drives that allow passage between the wheels. The middle middle car is a multifunctional car in which a restaurant can be accommodated. The 374-ton train can reach 400 km / h on high-speed lines in regular operation. Since it fits into the British PG1 clearance profile, it can also drive on many other routes with a correspondingly small clearance profile. The AeroLiner3000 will not have any negative effects on the existing infrastructure.
Drive system
The drive system has 12 MW of drive power to achieve maximum speed. The power is evenly distributed over the 44 motors with 270 kW power each suspended in the car body by the chassis. Pantographs for the 50 Hz-25 kV overhead line network are installed on both end cars. Usually only one of these is lifted so as not to further stimulate vibrations in the contact line. In normal operation, the train brakes by coasting. The regenerative motor brakes can be activated for greater deceleration. In an emergency, the train also activates eddy current brakes at speeds above 250 km / h in order to meet the TSI high-speed standard. A friction brake is only used as a parking brake. The intermediate cars are permanently connected to one another by a central buffer coupling. Half trains are virtually coupled with one another in order to increase operational flexibility within the scope of ETCS Level 3 train protection. A 405 m long train with 1400 seats consists of two virtually coupled half trains.
aerodynamics
The design takes aerodynamics into account mainly through the super- elliptical shell surface between the nose and the roof of the end car, the completely clad wheel sets and car transitions and the smooth underbody. The nose of the end car has been designed with a medium degree of slenderness, as it is assumed that future tunnel portals on high-speed lines will be built in such a way that they reduce the head pressure wave of a train. The crosswind stability of this lightweight train is currently being investigated in the wind tunnel.
Lightweight construction techniques
Consistent consideration of lightweight construction techniques and optimized aerodynamics are intended to reduce operating and maintenance costs as well as CO 2 and noise emissions. The car body structure consists of continuously bent steel tubes with a constant diameter, which are joined together with laser welding. The total weight is around 20% lighter than that of conventional car bodies. Furthermore, the weight savings enable a slim structure of the car body, which makes the double-decker car compatible with the TSI-PRM standards and offers better seating comfort than many British trains currently in operation. The load-bearing structure of the car body is adapted to the normative requirements and loads to ensure stability. This means that the interior design can be optimized with regard to the intermediate floor, for example, which enables a double-decker concept with high flexibility.
Passenger comfort
Passenger comfort is to be improved by a seat pitch of 830 mm, low noise level, pressure fluctuations and vibrations as well as improved air conditioning and interactive, smartphone-based passenger information. The AeroLiner3000 design aims for a five-minute stay in train stations. For this purpose, the luggage is loaded by a robotic luggage conveyor system. The passengers check in their luggage in the middle of the platform.
lighting
The lighting concept makes use of organic LEDs (OLED), which emit glare-free and dimmable light. OLEDs are suitable for this application because they can be installed in the ceiling with a height of less than 3 mm. The lighting system works together with electronically darkening windows and proactively takes tunnel journeys into account.
implementation
A fully developed 9 m long mock-up was created for ergonomic studies and as a demonstration of the feasibility and plausibility of the concept . This was presented as a world premiere at InnoTrans 2016 in Berlin . The next step is to build a test car and let it run on the UK network.
