Thank you so much for your insights gentlemen, I have some follow up questions!
------------------------
PJW:
# overlaps just measured to be 180m beyond signal and placed without thought within S&C.
I thought i did place them with thought, but you just can't avoid swinging overlaps sometimes, or are you thinking about something else? I'm thinking at Station E signal 10 or 12 overlaps.
----------------------------------
Peter Martell:
Yes you are very astute in your obvservations, especially in my lack of understanding for OTW! You mentioned that track circuit sequencing and Treadle is required, is this all I would need to draw on the plan, or do I need further explanatory notes/calcs (once i find out how to do it of course) - where can i find out about this?
Also I have used SI's instead of JI's at the end of a platford for example, where the train would start from stationary - have I wrongly assumed the use of SI's for this application? When do you use SI's and when do you use JI's?
Regarding my Trap points in the freight yard A, only my 202 are traps, as the rest of the points act as trap points anyway due to their normal position? the reason iwanted to make 202 traps is because it prevents a head on runaway train collision..
Regarding the runaround signalling at the down goods loop, the reason i ran around with the signals 603 and 605 is because of those arrows that suggest they only want trains to move off in that direction? my preset shunt and call on signal is a mistake.
All other notes that you both have commented are silly mistakes, which I will hopefully correct with practise (this is my 2nd attempt at the layout).
Thanks again,
Priyank
