There appears to be some sort of 'signal failure' on the outer rail in the Gloucester Road area, suspending the OR service and this has been the case for two or three days now. Travelling Eastbound last evening it appears this failure affects the EB/IR services at the junction - my train (at around 17.40) was delayed in EC station and then at the approach to the junction, for 1 minute and approx 5 mins respectively and there was considerable blocking back too. I don't know how trains are 'called by' failed 'signals' under the new signalling but that may or may not have been the reason for these delays since we were not 'tripped' if indeed this is still a procedure under the system.
Yesterday 254 points at Gloucester Road failed around 0525 and were secured in favour of westbound District trains for the remainder of the day.
If required to move through an area of failure, there aren’t any signals but “hold” boards of reflective material and all trains must be held while one train at a time makes the move in Restricted Manual (maximum 9mph). Trainstops are not used in CBTC areas. Tripcocks can still be activated though on other objects.
