I would assume due to the lack of a JI at EF205 there is no natural route from EF205 to EF427 so trains would have to be authourised to pass EF205 at danger- (D notice or handsignaller)- with 805 and 812 collared reverse on the panel and stopped at EF427?
I assume due to the POS 4 feather on EF101 a route is not available to EF427 to again degraded working and authorising of passing a signal at danger.
I would assume the SI on EF719 giving a 2 would be for the down slow and down fast and a natural route does not exist between EF719 and EF427 so again if a service is required of the branch it would be degraded working- ( D noticed or handsignallers)
I find EF427 confusing- a lack of a JI would suggest the lack of a route to the down fast, its a 3 aspect signal so I assume it leads to a bi-directional signal on the up slow?? Therefore trains brought into Platform 1 under degraded working would have to be authorised past a signal at danger under degraded working.
Can someone look at this for me, I did it under exam conditions probably round 32 mins, loads more I could add but you only have so much time, all i'm looking is a pass :-)
