Point locks
| Глоссарий в железнодорожной технике |
Mechanical devices attached to points to ensure that they remain fixed for the passage of a train through them. in many countries, they are a legal requirement where passenger trains are operated. points are also electrically locked by their control system and by track circuits occupied by a train passing through them (detection).

Track circuits, английский
Means by which the passage of trains is detected and the information used to control signals provided for train safety and control. the simple track circuit consists of a relay energised by a low voltage circuit fed through the running rails of a section of track. each section is electrically isolated from others. the energised relay detects no train present and can be used to switch power to a green signal light. if a train enters the section, its wheelsets will short out the circuit, causing the relay to de-energise and switch off the green signal. the relay will now switch on the red signal light. the light remains red until the last wheelset of the train clears the section, allowing the track circuit to be restored and the signal to return to green.
