    In half-duplex, communication transmission takes place from both sides, but only one direction at a time. Likewise, a railway track can operate from one direction either a train can enter or leave a railway track.

    Currently, now it is moving to full duplex. One for up and second for down

    As we all know that in a railway track, only one train can travel on each track. just like half duplex which we can do operations bidirectionally but only one process at a time.

    how ?? i didn't get it....I thought it should be full duplex, because 2 lines can transmit data on one & receive on other simultaneously, after all that is what Full Duplex means....isn't it ??
