Hello PJW,
Thanks for your comments and further clarification.
Hello greensky52,
I will be the first to admit that my layout was not completed under exam conditions so please do not be discouraged. I may be in the same boat or worse in a slower, perhaps sinking boat compared to you. So at best may be a fellow traveller.
On a more serious note, I have come to the conclusion that it is quite hard to complete the layout to the level of detail that I may have posted. But I think for preparation for the exams I did it more to ensure I understood the Study Pack and this forum has been excellent in giving me that opportunity to test my understanding.
And to PJW, Peter Martell who manages this forum and all who have contributed, thank you very much!
If I may share my strategy for the exams, it will be to demonstrate that I can work out the:
1. non-stopping headway
2. Stopping headway
3. Signal the busy station/junction (there is always one) and complete signal route boxes that show Main, Warners, Call-Ons and Shunts, show junction signalling and possibly transition form 3 aspect to 4 aspect signals and vice versa.
4. Show how freight standage and especially the turning of engines can be done.
5. Single line signalling (always)
6. Level crossing if there is one. Incidentally level crossing has not be examined for some years now and not forgetting
7. Trapping
8. Track circuit boundaries
So rather than put in all the signals and track circuits I will have to be selective in view of time constraints to demonstrate that I desreve the marks.
Best wishes to all for the exams!
Alex
