Dan,
Perhaps you and others can offer some experience or suggestions, or even speculations, for my problem.
THE SETUP:
I have an above garage space that will be a few inches over 16' x 23' - but that's under a 45 degree roofline that intersects the long walls at 54" above floor level. With this in mind I've had to plan a layout height ranging from 40" to 48", with a staging return loop with three passing tracks dropping from the 40" level to 37" (most of that will be below an end wall and curve around under the 48" area along one long wall.
The basic concept is that of a mythical southern Indiana branch line, the Big Fork and Diehl RR (reporting mark BFD), that leases engine service and critical area trackage rights with some class 1 lines (Wabash, Nickel Plate and possibly even C&O - I'd like to see a 2-8-8-2 dragging in empties and schlepping away 20-car coal drags, in addition to NKP Berks towing reefers stopping for re-icing and a Wabash P-1 4-6-4 heading up a train of blue heavyweight cars with a Bluebird drumhead at the end of the observation car), and has it's own out and back run from the big yard up to the mines and branch terminal, shuffling hoppers, reefers full of Buxom Melons, and cars of cement and limestone slabe as well as miscellaneous freight and local passenger service.
Along the West long wall, 40" level, track enters from staging loop via tunnel near North short wall and enters the long double ended interchange yard, passenger station, engine service area, shops and MoW yard at Big Fork, returning via balloon loop in southwest corner; West side of balloon loop also goes:
1) along West wall headed North into tunnel and begins down grade to connect to staging loop2) between that track and the return side of the balloon loop begins 2% grade headed North, crossing North entrance from staging at 44", then East, doing a 35" radius climbing loop around the Piedmont peninsula (station, cement plant, limestone quarry, and a melon farm - the liftout access in the middle of it) crossing over itself at 48" and continuing East then South along East wall to a 33" baloon loop with a wye, small yard, engine terminal and station at Diehl at the south end; two coal mines are in the Northeast corner and along the outside (West) of the East side balloon. Various small industries such as stock watering, REA, coal and fuel dealers, brewery, produce distributor, steel fabricator, chicken packer, grain elevator, scrap yard, etc. are scattered around Big Fork, Piedmont and Diehl, offering lots of switching activity for BFnD way freights.
Stair access is in center of south short wall.
NOW - THE QUESTIONS: that East wall area at 48" height will have just
6" of vertical wall for backdrop before hitting the 45 degree slope of the ceiling (rises to 8 feet, then flat across the center)I'm concerned about how to handle the transition from vertrical to slant (small radius coved? - and don't even mention the corners!), and wondering about lighting. Track lights sound attractive - mounted behind a valence perhaps. I'm thinking the backdrop color should be a fairly pale blue to reflect more light, but am concerned about complex shadows and color cast.
