Playing Marylebone & have just set the route from JF3 to A786 at Northwood & surprisingly it cleared even though train C423 seems to be occupying the tracks Post has attachments. Log in to view them. Log in to reply |

Without looking at the scheme plans, there are many track circuits on the local lines that are grouped together (as per the box indications) rather than shown individually (as in the Interlocking Machine Rooms). We didn't pick up on any inherent errors with clearances on the local lines during testing.

It's true that DJ.DL.DP.DT track circuits are shown as one on Harrow-on-the-Hill's diagram, which includes the overlap of A786 signal, but further track circuits are not rolled into that indication, so JF3 signal wouldn't be off with the track circuits between JF3 and A786 showing occupied on the diagram.
