double-main folded-dogbone in N-scale

    This sound feasible to you guys? the space I'm gonna be working with is probably gonna be 4x8, might be able to squeeze it to 5x8, depends how the furniture gets rearranged. I'm thinking maybe 1, maybe 2 crossover exchanges between the loops. the only siding I'd want on the outer loop is a spur, to eventually connect to an external staging yard, not a priority at this point. Probably a few sidings w/industries on the inner loop.

    I don't have a lot of rolling stock, so sidings aren't a priority...I mostly like to see 'em roll anyways.

    Finally getting to build a layout after years of nothing! anybody got any plans similar to this, so I can get a feel of how the spacing works out?

    Oh, I plan on a decent elevation change for the inner loop of the dogbone, so that it doesn't just sit next to the other 2 tracks.

    If you intend to run more than one train, a double main makes a lot of sense on a small layout. On a small layout, you don't have enough room for two passing sidings, without them being on top of each other anyway, so a double main is a better solution.

    Grindar, Mikes Small Trackplans website and Thor's Trains website have some trackplans you can look at.

    Yeah, this one kind of caught my eye

    but make it into a double main all the way around, instead of just over the bridges. My planned space is bigger than a door, so I should be able to add the second main without sacrificing turn radius on the inner loop? I'll probably nix the whole yard, but put a couple sidings in it's place, and move the spur to face down a narrow side for when I have money to build an add-on yard (all those switches (O.O). If I have time later, I'll start knocking something out in RTS.

    Any thoughts on this?

    That should be doable on a 5x8. I would draw it out first, like you plan. Good plan to start with. Industries, an area for a town and scenery. Good choice.

    Do you guys think 2" is enough clearance for the bridges? Also, anyone got any recommendations for the bridges? I was looking at some Kato double track easy is it to interface the unitrak with regular code 80 flex track?

    If I do them as single track bridges, what do you guys think about maybe doing one main as truss, one as plate girder to try and say "built at different times", maybe accentuate it a bit with weathering?

    5x8 is huge for N scale. You can have really broad curves so you can run auto racks and passenger cars and they'll look great. You can get a huge folded dogbone in that space, with lots of room for scenerey and trains to boot.

    Are you measuring that railhead-to-bottom-of-bridge or railhead-to-railhead?

    2" railhead to bottom-of-bridge...

    I don't plan on running any double-stacks, but some auto carriers would be nice. That should be the tallest thing I'll run.

    That's 26'8" in N scale. Real double-stacks ride 20'2" high with hi-cube containers, and even assuming that models may ride a little higher, that's more than enough for anything, including every high-and-wide load I've ever seen.
