Hello PJW,
Thank you once again for all your comments. I have gone through your comments and would like to clarify the following:
MAY-FA. The standard NR/SP/SIG/19609 Colourlight Junction Signalling suggests that MAY-FA is possible for a road with divergent speed of up to 40 km/h when the straight road is between 64 km/h to 120 km/h. I am aware that in Appendix S of the study pack that MAR is applicable when the speed of the divergence from the straight is above 16 km/h. So which to follow for the exams? I have extracted the relevant parts in this posting.
Hand written annotated comments. Yes those are mine as clearly it would appear that there was a typo of sorts under the operating requirements. Effectively that was how I assumed the movements to take place for passenger trains between H and C and trains from A joining and uncoupling at Station F.
Description of runaround movements. Some clarification is in order please. Standing of freight trains is required
