Abstract

A rail vehicle system includes a set of cars for transporting passengers. The set has two end cars, at least one driveless central car and at least one central car constructed as a traction car having at least one drive unit. In order to achieve greater flexibility in assembling a rail vehicle system, in particular with regard to improved scalability of traction power, the traction car includes a power supply unit for the drive unit and has at least one voltage transformation unit and a power converter unit.
