As a newbie to both O Scale as well as this board it didn't take me long to discover SCARM, and I've quickly started to daydream about a possible permanent layout in the basement. I'm at least a year off from starting anything physical, as the available room needs to be cleaned out and completely re-done, but it never hurts to start planning early. The room itself is 12' x 24' with a 6' x 8' cutout under the laundry room. As a good portion of this room needs to be usable for other purposes (either a TV lounge and/or child's playroom), I will be pretty much limited to a 12' x 12' section, with the 6' x 8' cutout on one end (on the right side of the proposed layout as viewed in the 1st two images). The cutout and back wall are formed by the block wall of the basement, though the left side is a typical interior wall which I can (and intend to) tunnel through in the future (hence, the siding at the back left).
The setting for the layout is that of east central Ohio, i.e. Appalachian foothills. As I'm a Polar Express fan, it will be winter with snow covering the ground. I'm a fan of late steam & early diesel, so figure the time period as the 30's through 50's. I enjoy running both passenger & freight, as well as lager late steam, so I've set the main line at a minimum of O-72. I planned it using Atlas O track, as I'm somewhat familiar with their product from my childhood days w/HO scale as well as the available selection of curve radii. However, I'm not committed to that brand. Hopefully the supply issues I've read about will have been resolved by the time I'm ready to build.
I've put in a simple loop of double main line running around the longest part of the layout, minimum curve of O-72. I'd like to use the double-track Atlas O Pratt Truss Bridge for the crossover (does anyone know the spacing between the tracks of this piece? Or is it however you decide to lay them? Also, does anyone know how far below the bridge track level the bridge frame extends, so I can calculate the clearance below?). There's an alternate main line doubling as a yard lead running around the back of the layout behind the yard, also with O-72 curves. Access to the yard will be off of the alternate line, with yard curves being O-54 for space reasons. On the inside of the innermost yard track I'd like to put some sort of cargo loading facility for boxcars. I'm thinking of trying to put a small diesel service facility on a spur in the back right corner behind the yard, also. Further down the alternate line there will be access to the turntable (also accessible from the inner mainline loop) - both with minimum O-72. As I like late steam and want to keep my options open, I'm thinking about using Millhouse River Studio's 34" turntable. I have no idea what spacing I should have for the tracks off of the table, so I went middle of the road with 10 degrees. I hope to put a coaling tower, water, and sand structures for steam engine service on the track coming off the turntable that ends under the bridge.
A narrow radius return loop of O-54 will come off of the alternate mainline/yard lead, with access to a coal mine (I like the one discussed here https://ogrforum.com/topic/coal-mine-kit and here https://ogrforum.com/t...mine-and-power-plant). As I don't have room for a siding for the mine, I've decided to bury it in the mountain behind the facility. Perhaps not very prototypical, but space is a luxury I just don't have. I don't have much rolling stock at this time (working on that ), but most coal hoppers I've seen in the catalogs should handle O-36, IIRC. As it will be buried, how the cars look on track is not an issue.
I'm planning on putting access panels between the elevated mainline & the yard, inside of the mountain (for tunnel access), and perhaps within the reversing loop as well. I'm hoping I haven't had too many burgers & beers to get into the corners behind where the roundhouse will be, but I might have to eliminate some of the shorter tracks behind the turntable for the sake of access and create a panel w/in the loop.
That's about all for now. I'm sorry my SCARM skills aren't such to present things better, or place buildings, cutouts, etc. Guess you'll hafta use your imaginations for now. Would love to hear any feedback, suggestions, etc. that you guys have. Thanks.
