2002 Mainline Layout answer

[adikarina]

Peter,
Thanks for the attached examples and comments. Found them useful to read and understand. I was wondering if you have something similar for the Rapid Transit Layout. I am sure it would be useful for all LU candidates. I have been searching high and low for such an exapmle.
Thanks
Regards
Aditi

As a late addition to the Study Pack (will be included for the 2009 edition) I have produced a suggest answer for 2002 together with a commentary explaining the rationale for some of the decisions and sometimes higjhlighting areas of improvement that have become apparent in retrospect.

This was primarily undertaken in connection with the London Study Group but is placed here so that others are able to share the information. Note that it is not complete in that no route boxes have been provided and although the key track circuit divisions have been shown this is not necessarily the totality and therefore the sections have not yet been individually identified. The primary purpose of the exercise was to concentrate on the provision of signals to meet the specified requirements.

Separate attachments are provided for the text and the various portions of the layout; I hope I have made a reasonable compromise re resolution and file size. (Note despite the nomenclature there are corectly only 4 portions of layout).
