Interlocking, английский
- A general term applied to equipment that controls setting and releasing signals and points to prevent an unsafe condition of the signalling system arising during the passage of a train.
- Блокировка; блокирование; запирание
- Being joined or connected so that neither part can be operated
- In signalling, a system to prevent the setting up of conflicting routes. at first they were mechanical, then electro-mechanical. now they are largely computerised using a two in three voting system or similar protocol. also note the term ssi (solid state interlocking). in the us, the term interlocking refers to an area where junctions and signals are under the control of a signal cabin or "tower".
- Interlocking of points and signals, through the locking frame in the signal box, prevents the accidental setting up of conflicting routes.
