FAG Wheelset Bearings in the Fully Automated Nuremberg Subway
As of 2006, a new fully automated generation of vehicles without drivers, developed and built by SIEMENS AG in Germany, will be put into operation on the newly-built U3 subway line in Nuremberg. Unlike its predecessor, the new DT3 vehicle type has a panoramic section instead of the driver’s cabin and a passageway between both halves of the double car.
The higher investment costs for automated operation are offset by lower energy consumption, greater safety thanks to numerous safety measures, as well as more flexible and needs-based use of the fleet.
Whilst conventional vehicles travel in intervals of a maximum of 200 seconds, fully automated operation allows for intervals of 100 seconds and means that vehicles can be made available within minutes during peak times. Continuous data exchange between the route and the vehicle ensures safe operation. Video surveillance in the passenger compartment and in subway stations enable the control center to react quickly.
The transitional period until 2007, during which conventional and automated trains will share a stretch of track, will be a first.
FAG supplies the wheelset bearings (rolling bearings and housing) for the DT3’s chassis.
