Thank you for your detailed comments and encourgement.I have done this based on the knowledge gained from your comments previously posted in the forum.But still i want to gain more technics from you.
1.If treadle operated condition is proved for call on move, then time delay(approach control) not required is't correct?
2.Is it necessary to provide LWR for all shunt movement eventhough not specified in route table.
3.The note "Permissive working permitted in platform lines" not given in the layout, So i have assumed that "No permissive move".
4.How to mention overrun protection for the route 161A(M)?
5.For the route 161A(M) comprehensive approach locking:
FC,FD,(FE,FG OR 244 R),(FH OR 244R)--------149 ARAFOAL.
6.How to find the time dealy for junction signal having MAR, ROL less than 55m-from the notes of yours re time values for IRSE exam purposes.
7.Explain the principle behind indirect opposing locking and how to find?
[124B(M)-135B(s) is indirectly opposing route]
