(4) SM of the block station working the IB Stop signal on becoming aware that such a signal is defective shall, before dispatching a train, treat the entire section up to the block station immediately ahead of the Intermediate Block Post as one block section and issue a written authority to the Loco Pilot to pass the defective Intermediate Block Stop signal at ‘on’, without stopping at the signal, in accordance with the procedure prescribed by Special Instructions. S.R.3.75.1. The Loco Pilot of a train shall not pass an Intermediate Block Stop signal that refers to him when it is at ‘on’ or defective unless :- (1) Authorised to do so by Combined Authority in form of PLCT (T/C 1425 or T/D 1425) by rear SM at the time of leaving that station, or (2) Authorised by rear SM on telephone provided on signal post with PN obtained for Line clear from station in advance.
