Hi Peter,
My calculations on the layout worked out to be 4 aspect on the mainline with nominal average spacing of 1000 m.
Taking account of the derivations for Safety 0.5s<=D4<=0.75s and
Service based on D4<=(DGR/3).
I am a little confused on the branch line. Given statements points that the branch line require isolated 3 aspect signalling, but cant find the stop-stop distance. Please help me.
Thanks & Regards,
Arpan Singhania
