Hello Peter,

Sorry for not making the deadline of 26th March 2010.

Appended please find my workings.

I have some questions please:

1 While the calculations show that 3 aspect signalling can support the headway requirements, the model answer has 4 aspect signalling in the vicinity of Station D. How was this conclusion arrived at? I mean the calculations do not show 4 aspect is needed.

2 Single Line on the Branch - I do not see the need for stopping headway calculations on the Branch. Three aspect signalling can support the speed of 120 km/h.

Look forward to your reply

Thank you & Regards
