http://jon.beigetower.org/trains/ N scale C&O 1950s Freelanced shortline aquired by the C&O somewhere a little ways off the New River Gorge. C55 Atlas track Circuitron switch motors Walthers/Heljan turntable motor operating the Peco turntable The building shown there is a company that manufactures and/or services mining equipment. Appropriate industry for the middle of the coal fields, I thought. Trackwork is probably around the 50% point, in some pics you can see it's still blue desert too for most of the layout.
Interesting to read of your turntable mod. More pictures? As already noted, perhaps a track plan? Boxcab E50
http://jon.beigetower.org/trains/trackplan.jpg Gray box with yellow X is the depot. Red box at the back is a coal tipple. Green box will be some random little house or two. Brown box will be one or two businesses - perhaps a gas station and something else. Orange box is the building visible in the pics. The track on the near side of the main across the street from the depot is the house track. The stub on the right of the depot is the coal unloading trestle visible in the pics. The main exits the layout at left through a tunnel portal right at the edge of the layout. Everything else should be pretty self-explanitory in this image. Next time I have the turntable bridge out of its pit, I'll take pics of the modifications as well as motorization. I built it so it could be disassembled if need be, but it's got a few tiny screws that are hard to deal with, so that'll wait til there's a need to take it apart. The whole pit and all lifts out of the layout, leaving two electrical connectors being all that's holding it in. Once it's out, the motor can be separated from the bottom of the pit, then some tiny screws hold the bridge into the pit.
