OO, conventional 12V sectional control. The layout has no return loops. Is there any good reason why I shouldn't wire the entire thing up with one common continuous rail and all the rail breaks/sectional switches being on the "other" side?
R.
I suggest that you not rely on rail joiners to link the common path, rather put a heavy gauge copper wire return under the board and frequent droppers from the rail to the return.
You might want to consider future expansion, when a more sophisticated circuit (both rail and electrical ) might be more appropriate.

No reason whatsoever. This is the normal basis for most cab control systems. In its simplest form, you would just replace the on-off switches with
2/multi way switches connected to 2/several controllers. The only restriction is that each controller must have a separate a/c supply.
With the possible exception of passing loops using turnouts with electrically switched rails, there should be no problems with your scheme - I use it.
