More wiring completed today. Actually most of the wiring was already in place and I was just awaiting the arrival of some more Lenz block-detection modules to fit in place and connect up. These boards provide track-circuiting for the new northern approach to the station and the first part of the hidden mainline climbing to the middle level.
Unfortunately what I thought would be a quick job took substantially longer than expected as I'd got some of the wiring wrong. That'll teach me not to try and be clever...
