DEPOTS AND FREIGHT YARDS

Rolling-stock maintenance depots and freight marshalling yards can employ signalling in a number of different ways. The most common is that the vast majority of moves taking place within a yard are not controlled by the main-line signaller. This is to reduce the workload of the signaller by not bothering them with regular shunting moves, something touched on in Chapter 5. The only signalling in depots/yards tends to be an exit signal and perhaps signalling in and out of a headshunt (depending upon its location relative to the arrival/departure lines). In this case, you may have ‘opposing locking omitted’ to enable both signals to be pulled off at the same time.
