Looks like a great project to sink your teeth into until the shed is sorted. Nice track plan too. I'm interested in the points because I hate the idea of controlling points by typing silly numbers into a key pad, but love the idea of also having analog lever switches to control the points even if DCC is the means of transmitting the change of states. Lever switches offer the playability and tactile feel of a signal box, and most importantly visual feedback as to how how roads, points and signals are set. Having a few clusters of point lever switches like a mini signal box also has the advantage that they can be sited near the yards they will control. I see you have a turn table, is that for steam ops, or for turning future 121s? If the former, could I suggest considering direct access to the TT without having to enter the shed, or route via an ash pit (e.g. end of day steam loco shunted to ash pit for cool down and servicing, before recoaling, rewatering and returning to shed ready for next days service). Anyway looking forward to seeing it develop. Like the spur for modular hookup.
