Hello Peter,
Appended please find my answer to the 2005 Part A Q1. Would appreciate it if you can go through it and let me have your comments.
I have two questions which I hope you can provide answers to:
1 What is current Network Rail practice with respect to overlaps for shunt routes. Previous postings on this website suggest Yes to overlaps for shunt routes as well. For Shunt routes do they have full and restricted overlaps?
2 In this paper, the notes on the layout states that "Calling On signals on 131, 144, 145 and 146 are running round only." Could you illustrate these movements on the schematic please? I have some problem visualising these moves.
Look forward to your reply.
Thank you & Regards
