An onboard control system for controlling operation of a drive system of a rail vehicle or a train of coupled rail vehicles is provided. The drive system has extraction equipment to extract electrical power from an external electrical power line for onward supply to one or more traction motors of the drive system. The drive system further has an onboard energy storage system for supply of electrical power to the traction motors. The onboard energy storage system is rechargeable by receiving electrical power from the external electrical power line via the extraction equipment. The train has plural operational states which are at least partly defined by command signals from an operator of the train specifying respective amounts of torque demanded of the traction motors. The onboard control system has a database which relates the operational states to respective current limit values. The onboard control system is configured to: receive the command signals and on the basis thereof determine the present operational state of the train, and control the drive system such that electrical current passing through the extraction equipment does not exceed the current limit value from the database corresponding to the present operational state.
