Attached is a rudimentary sketch to illustrate my staging yard. (remember, there are two such, very similar).
You can see, I hope , how it makes sense to me to simply reverse the entire B/C loop section, and thereby avoid other complications.? I looked at using an AR for each approach, e.g. L to N, or even just M to N, and similarly Q or R to S; in each case, there are use cases where the reversing block thus created could have a train entering and leaving.? Only the crossover bottleneck presents a single, unambiguous reverse vs don't-reverse use case.
I think, on the whole, reversing the booster would be best, if only the booster fed only sections B and C.? However, given that I still have hopes of initially running both staging areas from one booster, as shown, that option is off the table, leaving me with only one - reverse using a DPDT relay dedicated to each staging yard, as shown.? I don't want to use an AR here, as an AR will be used for track section D, and it will be connected to B, forming the dreaded "adjacent AR" conundrum.
