    Conductors: overhead line or; conductor rail, usually a third rail to one side of the running rails. Conductor rail can be: top contact: oldest, least safe, most affected by ice, snow, rain and leaves. Protection boards are installed on most top contact systems, which increases safety and reduces these affections.

    Operation of the overhead conductor rails at Shaw's Cove Railroad Bridge in Connecticut. In a movable bridge that uses a rigid overhead rail, there is a need to transition from the catenary wire system into an overhead conductor rail at the bridge portal (the last traction current pylon before the movable bridge).

    In Hungary a conductor may assist the train driver in testing the train's air brakes, and sometimes they have to lead the shunting, mostly when the trains are switching lines. Hungarian train conductors are responsible for the departure of the trains. In each station they give the permission to move on by giving a ready signal to the train driver.

  5. Third rail - Wikipedia

    en.wikipedia.org/wiki/Third_rail

    The first idea for feeding electricity to a train from an external source was by using both rails on which a train runs, whereby each rail is a conductor for each polarity, and is insulated by the sleepers. This method is used by most scale model trains; however, it does not work as well for large trains as the sleepers are not good insulators ...

    The train could then proceed, and a second train could follow. In the earliest days, the second train could proceed after a designated time interval, as on double lines at the time. However, after the Armagh rail disaster of 1889, block working became mandatory. Seeing the train staff provided assurance that there could be no head-on collision.

    Diagram of New Haven system forerunner of 2 x 25 kV system. [16] The 2 x 25 system traces its roots back in the upgrading of the electrification of the New York, New Haven and Hartford Railroad witch was electrified in 1907 and upgraded in 1914. The line was initially electrified with 11 kV 25 Hz system and then upgraded as "2 x 11 kV" system ...
