Product description

PTB - data communication backbone based on reliable, real-time power line communication enabling transmission of critical data over the freight train bus bar; thereby saving costs compared to a solution with separate data lines in wagons and couplers.

PTB is based on plc-tec AG’s own power line communication technology PLUS (Power Line data BUS). PLUS was originally developed for mission- and time-critical applications in avionics, ensuring the fulfilment of real-time and reliability requirements. Such design goals are similar to the ones for PTB. With PTB an important step towards an integral communication solution for the intelligent freight train is made, enabling the following innovations:
  • Cost-efficient automatic coupling
    PTB provides a cost-efficient coupling solution which does not require expensive data bus coupling methods. The communication link is automatically established via PLC as soon as the electrical connection is made. No separate coupling of data lines is required.
  • Automation of train operations
    The electrification and the introduction of data communications in freight trains enables automation systems such as automatic brake testing, train integrity checks, automatic coupling, etc.
