@BurkusCircus52 posted:I don't know how plausible this would be, but what if, to get some more over/under action, you extended the BNSF extension in front of the doorway (using a removable bridge), and then had it go down and reconnect just after the roundhouse turn? This would require going with the bathroom-less option and probably losing Deer Lodge and the On30. Basically, it's turning the BNSF Connection into the third main and making Three Forks the out-and-return switching short line. Just a suggestion. And please post any progress you've made over the quarantine!
Burkus, I guess I don't follow, sorry. But thanks for the suggestion, and please feel free to clarify!
I could see extending the elevated BNSF to Great Falls, across the doorway at the bottom, with a long lift-out, and have it swing in the lower-left corner at Silver Bow to connect to the trackage now the UP junction, and so back to the outside mainline. This would not be a completely independent loop, there would be shared trackage between the turnouts on the left (the one in the clear space between tunnels (with a stream), and the upper left turnout that starts the BNSF elevated line. That could be worthwhile: redoing Silver Bow to make room for the new mainline to pass through. Usage would require that the door be locked, but that is OK; others do that sort of thing.
Deleting the bathroom option (no longer needed for me), would allow me more flexibility to retain Silver Bow in some form.
