The locals are divided into "branch" and "main". Both locals originate from and return to Dante Yard, represented by the staging tracks. The "main" local runs along a stretch of single track mainline, switching out empties for loads, and swapping out cars at the Norfolk & Western interchange at St. Paul. The "branch" local runs up a branchline, swapping out the appropriate cars, and shuffling around the piggyback cars.
Motive power for this operating scheme can be found
here.
An option for this operating scheme is to include through train(s) running down the mainline. They can be longer than the sidings and there could be as many as desired. Due to the fact that there are only two staging sidings which are only so long, these extra trains will not fit into the regular staging tracks. I could either build these trains by hand in the open layout (which isn't a problem), or I could use an interchange extension (see
Track Plan) on which to build the trains, or a staging extension (see
Track Plan) to properly stage them.
