Hello,
I would like to post my attempt on the 2000 mainline layout.
Some points I would like to highlight are:
1. While the calculations suggest 3 aspect signalling can meet the headway requirements, the requisite movements specified for the layout, the junctions on the layout made 4 aspect the choice.
2. For adequate trapping protection for the up and down mainline, I made some changes to incorporate points at the end of the Bay and Siding. I am not sure if this is acceptable?
3. Single line working using One Train Working No Staff
4. Although not indicated in the plan, bi-directional running at Station D and at Junction C was necessary in order for trains especially Freight engines to turn around after coming from the Down Frieght Branch to get to B.
I have have included: 1) my workings on the signalling aspects required for the non-stopping and stopping headway and 2) the notes relevant to signalling the layout.
I would appreciate comments on attempt please.
Cheers
