Actually I am familiar more with mass transit system. I was a tester in mainline project in SRT(State Railway of Thailand). However, I think it would be better to refer UK mainline practice because there are plenty of sources and information to learn and study.
#2a Breaking distance is only 1.33x400 = 532m and the next signal is 5Km then we need to have a red/green 2 aspect signal. Am I right? otherwise the driver will delay applying the brakes. Then the signal 31 should have been R/G signal.
#2b This is unclear to me. Please help explain that.
Consider breaking distance 1000m from mainline and 1.33x1000 = 1330m then
for example the distance from SI11 to SI13 is only 1100 which is not enough and unable to apply the brakes with sufficient distance.
#3 Yes I have missed the routes going to the siding. Then I'll update my aspect sequence.
#4 I saw ROL and I realise that probably there is a need for a shunt route to display in the aspect sequence.
Thanks
