Comments please.... HO scale shelf layout, 40 foot cars and 2 axle diesels, min radius 20 inches, Code 83 Atlas track I need a yard to make a 90 degree curve to get the necessary length. Curved turn-outs would be great, but I am considering using #4 turnouts, all left handers to get the arrangement shown in the drawing. I have layed this out on the shelves to see if it is a go... it works fine, except there is a bit of "snakie-ness" as the cars go through the turn-outs, straight-curve-straight-curve-straight-curve. On the drawing, trains will enter the yard on the "mainline" track #1, the engine will escape by coming back over the crossover to track#2, then pull the cars out of track #1 and push them into track #3, #4, or #5. I would rather have the "mainline" and "escape" track on the front side of the shelf, but then this puts the entering train going through all the turn-outs, around the sharpest curve, and on the shortest yard track. Anyone see any problems here? Or a better solution?
