2002 Mainline Layout answer

[PJW]

As a late addition to the Study Pack (will be included for the 2009 edition) I have produced a suggested 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).

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

I am afraid not; you and me both.
The Study Pack certainly needs much more Metro content but unfortunately it is not within my competence to add this myself. Peter Clifford did give me some stuff including the Appendix M Step-by-step generic guide that is included within the 2008 edition, but just did no have the time to be able to do for the Metro layouts the same sort of overall commentary that I did for the Mainline ones, let alone something as detailed as I have now done for 2000, 2002 and 2006.

Certainly we are looking for a volunteer from the Metro community who would be able to do this for the 2009 edition (and indeed could be distributed like this one if done prior) VOLUNTEERS PLEASE; Metro students try to twist a few arms of likely victims that might be press-ganged!
