An electric multisystem on board a rail vehicle comprises a first connector means (22, 23) configured to connect either a first connection point (a) of the electric system to an AC-contact line or a second connection point (b) of the electric system to a DC-contact line. A transformer (3) has a primary winding (4) to which the first connection point (a) is connected. A line converter (13, 7) is connected to the secondary winding of the transformer and has the output connected to a DC-intermediate link (14, 18). The secondary winding of the transformer is divided into two halves (51, 52) connected in series and a second connector means (70, 71) connects the second connection point (b) to the secondary winding of the transformer by connecting the DC voltage to a midpoint (55) between the two halves (51, 52). A control unit (19) controls the line converter (13, 7) to together with the inductor of each half of the secondary winding used as a step-up chopper inductor acts as a DC to DC-chopper for adjusting the level of the DC voltage delivered to the DC intermediate link (14, 18).
