Thank you for the reply.
Your explanation now makes it clearer. I will use it to test my understanding on other examples.
I must say that this is very different on how this is presented with the British Rail Control Tables notes (page 15) which you sent me. If I used BR practice for the same example of 114 then under Approached Locked When Signal Clear and Tracks OCC the entries will be:
BL, BM, BN
(BP w 205N)
(BR BS w 206N 122 USED)
(AN AP w 206R 116 USED)
Is this correct and can I use this? Really choosing what is easier to understand and apply.
For the matter on Overrun Protection, my Notes Applicable will say "UK Mainline practice (approx year 2000) adopted..." so presume will take care of that. But good to just think of it and include Points Normal or Reverse for flank protection.
Thank you & Regards
Indeed there are different presentations, sometimes dependent upon technology. If you find that one an easier one to use then follow it- the N in that situation would infer "points set and locked" not "set locked and detected" and that may be something to include in your General Notes.
This is why it is difficult for someone who doesn't really use any particular standard but tries to pick up information from various sources- I must admit that I was looking at your CTs on the basis of how I thought you'd have learnt at Signet.
Not convinced by what you wrote (I'll have a look later at the notes to see what they were actually saying) , but you could certainly write-
BL, BM, BN (AN w 205R)
section in rear 118: [BP, (BR w 206N)]
section in rear 116: [AP]
Yes if you declare c2000 then you need not put in the Overrun Protection explicitly (though I still recommend just thinking long enough about it to make sure that you haven't overlooked flank point calls).
Remember above all success in the exam is about speed and getting the basics for all the routes- do not worry too much about getting everything 100% right.
