English to Greek Tech/Engineering Transport / Transportation / Shipping Railway Signalling

"Stop/Non-Stop" controls are in place on the Down Line at Bottisham Road AHB (nothing special applies to Up trains). The crossing "strike-in" controls are south of Waterbeach and so, if a train stopped at the station with signal 235 off, it would take so long to reach the crossing that there would be a serious risk of road users thinking the crossing had failed. Therefore the signal only clears when the ****berth**** track circuit has been occupied for about 30 seconds or the non-stop button has been pressed. This must be done separately for each train.
