Abstract: A system for managing the operation of trains on a railway network. The system comprises: a train, including a control system which is configured to operate the train in each of two power modes: a hybrid mode in which power is provided to the one or more traction motors from an on-board generator assisted by one or more on-board electrical storage system, and a battery-only mode where power is provided to the one or more traction motors just from the one or more on-board electrical storage systems; and a remote control centre configured to transmit, to the control system of the train, operating data defining one or more regions of the railway network in which the train should operate in a given power mode of the two power modes.

Abstract: A train for travelling on a railway network including routes with external power supply infrastructure and on routes without external power supply infrastructure. The train includes a control system configured to operate a drive system of the train in each of two power modes: a hybrid mode in which power is drawn from an on-board generator assisted by one or more on-board electrical storage systems, and a battery-only mode where power is drawn only from the one or more on-board electrical storage systems. The control system is configured to receive both: a driving setting selection, and an operator specified power mode selected from the two power modes, associated with a respective region of the railway network. Whilst the train is in the respective region the control system is configured: to modify one or more parameters associated with the operator specified power mode, or to change from or ignore the operator specified power mode, based on the driving setting selection.

Abstract: A train for travelling on a railway network including routes with external power supply infrastructure and on routes without external power supply infrastructure. The train includes a control system configured to operate a drive system of the train in a battery-only mode where power is drawn only from the one or more on-board electrical storage systems. The control system is configured to: monitor an actual state of charge of the one or more on-board electrical storage systems; calculate a predicted future state of charge of the one or more on-board electrical storage systems, at a time in the future, based on the actual state of charge of the one or more on-board electrical storage systems and a planned usage of the train; and modify one or more operating parameters of the train based on a difference between the predicted future state of charge at the time in the future and a target future state of charge.

Abstract: A railway vehicle includes an energy storage system comprising rechargeable batteries for providing electrical power to one or more traction motors of a train drive system, and at least one casing forming a chamber in which the batteries are sealingly housed. The railway vehicle further includes a passenger compartment. The railway vehicle further includes an exhaust system for collection and discharge of combustion fumes generated by accidental combustion of the rechargeable batteries. The exhaust system provides a collection duct which opens to the chamber for collection of combustion fumes. The exhaust system further provides a discharge duct which fluidly communicates with the collection duct to receive the combustion fumes therefrom. The discharge duct is configured to discharge the received combustion fumes to the outside of the vehicle at an outlet port which is located to direct the discharged combustion fumes away from the passenger compartment. The exhaust system is configured to provide: (i) a closed operational state which in normal usage maintains airtight sealing of the batteries in the chamber and (ii) an open operational state which in the event of combustion of the rechargeable batteries enables flow of combustion fumes from the chamber through the exhaust system to the outlet port.

Abstract: A drive system for a railway vehicle is provided. The drive system includes a first power supply sub-system for supplying power from an overhead line or live rail. The drive system further includes an inverter joined to the first power supply sub-system by a DC link, the inverter converting the DC power to three phase AC power. The drive system further includes an electric motor for providing traction torque to the vehicle and connected to the inverter by a three phase AC link such that the three phase AC power from the inverter drives the electric motor. The drive system further includes a rechargeable traction battery connected to the DC link for providing DC power to or removing DC power from the drive system at the DC link. The drive system further includes a second power supply sub-system for providing three phase AC power to the drive system at the three phase AC link, the second power supply sub-system including a contactor moveable between a deployed position at which the contactor can make an electrical connection to a power outlet of an external three phase AC power supply network, and a retracted position at which such an electrical connection is prevented. The drive system further includes a first switch on the three phase AC link, the first switch being configured such that a closed position of the first switch connects the electric motor to the three phase AC link to allow the three phase AC power from the inverter to drive the electric motor, and an open position of the first switch disconnects the electric motor from the three phase AC link to prevent the three phase AC power from the inverter and the three phase power from the second power supply sub-system from driving the electric motor. The drive system further includes a controller which controls operation of the drive system, the controller being configured to provide: (i) a first circuit configuration of the drive system in which the contactor is in its retracted position, the first switch is in its closed position, and the electric motor is driveable by power supplied by the first power supply sub-system and/or the traction battery, and (ii) a second circuit configuration of the drive system in which the contactor is in its deployed position for connection to the power outlet, the first switch is in its open position, and the traction battery is chargeable by three phase AC power supplied by the three phase AC power supply network and converted to DC power by the inverter.
