So, before being put into service, an Alstom bogie equipped with all its components will have undergone at least 10 million fatigue test cycles which, in a period of just four to six months, will simulate nearly 30 years of service.
For example, Alstom has equipped the Ixege bogie for the Citadis tramways with more than 460 stress, temperature, torque measurement and displacement sensors.
With improvements expected to be made on the new bogie test bench, it will eventually be possible to simulate a route with even greater precision by incorporating possible track defects.
ALSTOM has opened a facility at its site in Neuhausen, Switzerland to test and validate the bogies for its trains.
In Venezuela, Bombardier Transportation, through its participation in the Frameca consortium, was awarded a $19-million Cdn order (12 million euros) for the manufacture or 56 motor bogies and 28 carrying bogies for the extension of the Caracas metro, which is one of the largest underground systems in the world.
This order, which also includes an option for an additional 96 bogies, brings the total number of this type of bogies ordered for the SNCF double-deck rolling stock to more than 3,200.
