Hold Signal


A Hold Signal works like a normal Controlled Signal, except that it cannot clear until a linked Release feature has been triggered by the passage of a train. The most common use of this is to place the release a short distance before the signal it is linked to, to delay the clearing of the signal and hence ensure that the train has slowed to a safe speed for a junction or terminus (cf. Speed Proving). However, you can also use a release triggered by a train on a different line, or only by trains with specific routes.
