Abstract
A railway vehicle for urban use has at least one motorized truck and at least one non-motorized supporting truck. The supporting truck is provided with wheels of smaller diameter than the wheels of the motorized truck which enables a lowering of all of the floor area of the vehicle except the portion which lies above the motorized truck. This lowering of the floor permits the use of a single intermediate step to be utilized by passengers and expedites their entry into and exit from the vehicle.
