That's my third variant above.
- you could simplify.

I'd be interested to hear more about that! I'm just working on something similar.
I'm going the other way by putting as much of the circuitry as possible into software for the PC. I went a similar to you in the past and cornered myself by making the electronics specific to the layout. It wasn't transferable to the next layout without a complete rebuild. :-(
My test version progressive block control design will consist of a number of circuit boards, one set of boards for each block. This will significantly cut down on layout hard wiring. The wiring between each block logic board is handled be up to four Cat 5 type cables, depending on the layout track plan. The system will be flexible and not layout specific, because it is based on one set of boards for each block. As my layout already has most signals operating the test version progressive block control system only includes the detection part of the signal logic.
For each block the following will be required on my system. The progressive block logic board will contain controller selection logic, track detection, automatic train slow down and acceleration control and the walk around socket. The track power board. The indicator panel board. The indicator is a led display which shows which hand controller is connected to the block. Cat 5 cables (with Rj45 plugs) between each logic board and indicator panel board. .
2 high current cables to the track of each block from the track power board. 2 high current and a common return to the to the power board. 2 supply wires and common to the logic boardPlus Suitable power transformers. Walk around hand controllers
If it works I then the design can be refined to combine the power board and block logic board, decreasing wiring again. 3 signal light logic could also be added without much additional wiring.
