Inspiro Metro Trains, Metro Warszawskie, Warsaw, Poland
Inspiro is an environmentally friendly and cost-efficient metro train model which is currently under construction. A total of 35 Inspiro trains will be delivered to Warsaw's metro operator, Metro Warszawskie, from the end of 2012 to 2013.
The train is being developed by Siemens in collaboration with Newag of Poland. It was designed by DesignWorksUSA, a subsidiary of BMW group.
Metro Warszawskie ordered the trains at a cost of €272m in February 2011. The European Investment Bank (EIB) issued a loan worth €139m ($184m) in late 2012 to fund the acquisition of the new rolling stock. The European Bank for Reconstruction and Development (EBRD) had previously provided a €80.6m ($106.6m) loan in September 2011 for the purchase of new trains for the Warsaw metro line.
The new rolling stock will alleviate road traffic congestion in Warsaw by providing a better alternative and meeting needs of the metro's growing passenger traffic. The new eco-friendly train will also help in reducing carbon dioxide emissions.
Inspiro train design and passenger capacity
The Inspiro trains will feature a driver's cab on both ends, enabling them to run in both directions. They will also feature Automatic Train Control (ATC) system.
The train will be 117.8m long and 1,435mm wide. It will comprise of six cars. The body of the cars will be built of aluminium. The front end of the car will weigh 500kg, which is less than that of any other normal train. The overall weight of the train will be six tons less than normal trains. The cars will have a width of 2.63m to 3m and a length of 17.9m to 20m.
The train will have a capacity of accommodating 1,450 passengers, including 256 seats and room to carry 1,194 people standing. Each car will have eight large doors and lighted information graphics, enabling easy entry and exit.
Lightweight techniques are being used for the construction of the train. The expected lifespan of the train is 40 years.
Propulsion and performance of Inspiro metro train
The train will run at a maximum speed of 90km/h with the traction system comprising four asynchronous motors per car. It will further be fed by a force-ventilated SIBAC series IGBT compact inverter.
Part of the axles of the trains will be powered by electricity through the 750V DC line using current collectors from the third rail.
Environmental friendly features of the Inspiro
Inspiro is being constructed using recyclable materials which will have a 95% recycling rate at the end of useful life of the train. The trains will be built conforming to the European fire protection and crash requirements.
The interiors of the train will feature no electronics or mechanics lockers in order to provide ample space for passengers. The materials used for the interiors of the train will consist of cork and wood.
The handholds in the train are specially designed and shaped like tree branches to be in line with the environmental intent and also provide enough support for the majority of passengers, who will travel standing. Sliding steps will be provided at one end of each car for passengers with restricted mobility.
The trains will have the added advantage of operating on an optional driver assistance system, as well as driverless operation and conventional operation systems.
The power consumption will be minimised by using LED carriage lighting and demand-controlled air-conditioning.
Germany is a leader in tram train operations, whereby infrastructure and rolling stock allow for through running between heavy rail and urban light rail systems.
Noise generated by the train will be reduced by implementing an electrodynamic braking system. The floors will be built using recyclable materials such as light textiles and cork-aluminium in order to absorb the sound.
Inspiro rolling stock for the Warsaw Metro
The new Inspiro trains will run on the Warsaw Metro system which comprises two lines. Up to 15 trains are expected to run on Line 1 of the metro, while the rest of the trains will run on Line 2.
Two Inspiro trains are expected to be delivered for testing by the end of 2012. One of these two trains was unveiled at InnoTrans in Berlin in September 2012.
