2008 mainline layout attempt

[MarkN]

For 10 and 12 signals, you have given them SIs rather than PLJIs. Although these are MAR for the turnout route, I would normally expect them to be PLJIs for such a signal. Conversely, 7 and 157 have PLJI for all routes. This is a problem for the route into the bay as this is not allowed.

Could you give a reference for the use of PLJI into a bay? I have looked through the group standards GK/RT 0031 and 0032 and cant find one. I would normally place an SI here as custom and practice but did not know that the use of PLJI into a bay was outlawed.
Thanks
