Hello Peter,
Thank you for your reply.
I must say you have not lost form - your response is as quick as ever!
With regards to my question on 4 aspect signalling, one reason I see the merits of 4 aspect signalling around Station D is that the shorter sections between signals will enable greater throughput and better capacity optimisation especially with trains of different speeds, stopping and not stopping given that there is a permanent speed restriction of 40 km/h around Station D.
Regards
Alex
