They were constructed in a careful fashion taking the platforms, tunnel clearances and bridges into consideration. The levels were tight, badly ventilated and unpopular with many commuters.
The upper windows could not be opened as not to cause injury to the passenger on the clearances of outside objects. The time it took a train to empty or exchange commuters was vastly longer due to the internal format of the carriages thus they decided to lengthen the train sets from eight cars to ten.
The inventor of such a train lay to a New Zealander chap named Oliver Bulleid, a British Railway mechanical engineer recognised for earlier developing many well known locomotives for GNR, LNER, SR and Irelands National Railways.
The 4DD however was at a disadvantage as only 2 sets were built giving a capacity of 552 seats each and not suitable for expansion across the network.
The idea of a double decker train rolls back to the very early days of carriage building. In France around 1870 many carriages has an open awning style seating area accessed by an external stair case similar to the old style trams across the cities in the UK.
It was always recognised that nearly doubling the capacity held by one carriage was far more efficient, reducing the length of a train set for smaller platforms and greatly attractive to the profit margins.
Being so popular with rail operators many countries run a Bilevel or double decker service, but not the UK. With such designs not only is the platform height an important design issue, but the both level heights and the height of the carriage under current structures including powered over head line equipment.
It is not without any state of ignorance that many industry companies have been tempted to put his issue of Bilevel rail travel in the UK to bed by bringing our infrastructure into a European standard thus attracting the change to rail operators to convert.
Developed by Andreas Vogler Studio and the German Aerospace Center DRL, the AreoLiner 3000 identifies the need for such travel on much of the the UK rail system with this tighter working or loading gauge taken into consideration.
It was all initiated off the back of the Rail Safety and Standards Board asking rolling stock designers to come up with ideas and future prospects for the future of trains. Titles ‘Tomorrow’s Train Design Today’ it was a competition to produce a train that would not interfere with the current basic infrastructure.
This EMU train could carry up to 1400 passengers built of two end cars and nine carriages, running of over-head power lines. Both end cars would have pantographs for the AC 50Hz 25K overhead electric power system here in the UK.
An aerodynamic design would reduce ’drag’ and noise. Lightweight built with low maintaince costs and reduced CO2 emissions. Overall this train looks very modern, bringing a new concept and healthier format to the railways in the country that desperately needs modernising.
Everything has been covered from passenger comfort, organic lighting built into the structure of the train carriages, sleek, clean and very attractive.
So what’s next for this new concept. It’s definitely not a pipe dream, this train will certainly set a standard for taking on our Victorian railway. If this train is able to solve and be feasible in the UK then it’s a great platform to introduce this set across the rest of the world.
The AreoLiner 3000 won several international design awards in 2018. The 9m long demonstration in Berlin in 2016 certainly gathered interest, so much to the degree they plan to build a 17m test car and drive it on our railway network.
With this excitement, it’s not if we see Bilevel sets on our tracks but more like when.
'A train, which looks as if the future has already begun: With aerodynamics, elegance and efficiency the AeroLiner3000 will delight passengers in the UK in a few years. Established know-how and design from Munich play a decisive role in the development: The architectural and design practice Andreas Vogler Studio designed the double-deck high-speed train in cooperation with the German Aerospace Center e.V. (DLR). Pioneering design, innovative lightweight construction, interactive control systems and revolutionary engineering make a unique combination for the AeroLiner3000. As a world premiere a 9m long full-scale mock-up of the train is presented at InnoTrans 2016 in Berlin taking place 20.-23. September. www.andreasvogler.com/portfolio/aeroliner3000'
