1. A trainline network access point connected to an intra-consist electrical cable of a consist, the trainline network access point comprising:

  • a network data signal path;

    a first communication module;

    a second communication module; and

    a network switch connected to the first communication module and the second communication module and configured to selectively add at least one of the first communication module and the second communication module to a ready queue upon receiving a signal from a respective one of the first communication module and the second communication module indicating that the respective one of the first communication module or the second communication module is ready to receive the network data and to selectively connect the network data signal path to one of the first communication module and the second communication module based on the ready queue;

    wherein the first communication module comprises a first processor, the first processor configured to;

    receive first network data via the network data signal path,modulate the first network data for transmission over the intra-consist electrical cable, andtransmit the first modulated network data over the intra-consist electrical cable,wherein the second communication module comprises a second processor, the second processor configured to;

    receive second network data via the network data signal path,modulate the second network data for transmission over the intra-consist electrical cable, andtransmit the second modulated network data over the intra-consist electrical cable.
