适用范围

Multitraction is used whenever – the tractive effort of the traction vehicle is not sufficient for the particular operational application, – different independent trains are linked together to form a longer train consist. In a train consist with more than one traction vehicle, one of the traction vehicles is always the Leading Traction Vehicle (LTV). The other traction vehicles contained in the overall train consist are controlled and monitored by the LTV. This arrangement means that communication between the different traction vehicles is necessary. Communication can be achieved by means of a cable link or a radio link. A radio link is for example necessary whenever there are wagons between the traction vehicles and whenever these wagons do not have any communication cables with appropriate infrastructure. Commands are generally sent by the operating personnel only to the LTV. If there are wagons between the traction vehicles, the effect of longitudinal dynamic effort and braking behaviour must be taken into consideration during risk analysis. This is applicable particularly when the overall train consist or individual train segments are very long and/or heavy. It should be possible for every traction vehicle to be used as a LTV or as a Guided Traction Vehicle (GTV) in the train consist. In all circumstances the operator should have a clear view of the track in the direction of travel. With a radio link, particular attention should as a minimum be given to the following points: • Allocation of traction vehicles in the train consist - location and address of the GTV and LTV in the train consist; - definition of direction of travel for each traction vehicle; - it should be impossible for any LTV to control any GTV from another train consist at any time. • Consideration of special aspects of a radio link - maximum number of all traction vehicles in a radio system: - unique address for each traction vehicle, - address stock, - number of traction vehicles or trains that can be simultaneously operated in the area of coverage, - response time; - radio response times; - radio interference/radio interruption: - local infrastructure (e.g. stationary repeaters), - train consist equipment (e.g. multiple receivers and repeaters on the train), - radio transmission system (see 9.2.4 of EN 50239): - EN 50159-1 closed transmission system, or - EN 50159-2 open transmission system; - area of application; - consideration given to regulations in the country of use; - availability of the radio channel: - exclusive or non-exclusive frequencies in the area of application, - guaranteed time for connection establishment or command transmission depending on the assigned frequency channel. • Response after radio interruption (by the operator and/or automatically by the train consist) - depending on the train length and weight involved; - depending on whether the Brake Pipe (BP) is segmented or unsegmented; - depending on the train speed; - depending on the duration of radio interruption; - depending on the local topography (e.g. tunnels).
