    A right-hand railroad switch with point indicator pointing to right Animated diagram of a right-hand railroad switch. Rail track A divides into two: track B (the straight track) and track C (the diverging track); note that the green line represents direction of travel only, the black lines represent fixed portions of track, and the red lines depict the moving components.

  3. Electro-pneumatic brake system on British railway trains

    en.wikipedia.org/wiki/Electro-pneumatic_brake...

    The brake continuity wire (a.k.a. trainwire 13) is fed with a 120 V DC control voltage from the battery and runs in a loop round the train, passing through various governors (air pressure operated electrical switches) in each carriage, finally feeding the power and brake control handle(s) in the driver's desk.

  5. Double switching - Wikipedia

    en.wikipedia.org/wiki/Double_switching

    The signal relay in question was switched only on the hot side, while the return current came back on an unswitched wire. A loose wire bypassed the contacts by which the train detection relays switched the signal, allowing the signal to show green when in fact there was a stationary train ahead. 35 people were killed in the resultant collision.

    The control switch of a diesel–electric locomotive that opens or closes the circuit between the main generator and the traction motors. [95] Get a knuckle To break a train in two, usually by shearing the knuckle pin in a coupler, often caused by the application of excessive head end power at startup. [96] [97] GEVO

  7. Train automatic stopping controller - Wikipedia

    Train automatic stopping/stop-position controller (定位置停止装置, Teiichi Teishi Sōchi) (TASC) is the name of a train protection system/automated stopping aid currently used only in Japan. It allows trains equipped with TASC to stop automatically at stations without the need for the train operator to operate the brakes manually ...

  8. Digital model railway control systems - Wikipedia

    en.wikipedia.org/wiki/Digital_model_railway...

    Digital model railway control systems are an alternative to control a layout and simplify the wiring and add more flexibility in operations. A number of control systems are available to operate locomotives on model railways. Analog systems where the speed and the direction of a train is controlled by adjusting the voltage on the track are still ...

  9. Railway coupling - Wikipedia

    en.wikipedia.org/wiki/Railway_coupling

    A coupling or coupler is a mechanism, typically located at each end of a rail vehicle, that connects them together to form a train. The equipment that connects the couplers to the vehicles is the draft gear or draw gear, which must absorb the stresses of the coupling and the acceleration of the train.
