I feel a bit silly but I'm struggling with question 16. Can anyone point me in the right direction? Or perhaps a fresh look at it tomorrow will make it clear.

There was quite a lot of work involved in working through all of these questions so it will take me a bit longer to attempt activity G23 for the 2004. For anyone starting this module I would recommend these exercises as they force you to think and not just calculate!]]>

1 I have completed the G23 Activity Layout Calculation that is based on the 2004 layout. However my train separation for headway, Green to Red and N values are very different from those given in Appendix W, Activity 1B Headways and Braking Calculations. I would appreciate it if you can have a look at it.

2 For the same 2004 paper, I have computed the stopping requirement from C to Station D and from Junction B to Station D although for the latter I did it more out of practice and as an after thought after I did from C to Station D. I am glad to have done so as the Stopping requirement from the Junction B to Station D is the more onerous of the two. I have appended another file to show the graphs, the time taken and the distance covered.

3 Speeds for turnouts. So far in my computations for stopping requirements, I have used the same turnout speed for both normal and reverse movements. Or can I use the maximum permitted speed if the move through the point is facing, normal and trailing normal ie. Without any diverging movement.

Thank you for your comments and do look forward to your reply]]>
