here is a quick diagram of the room:
the dresser can be moved and the entrance is in the area that I marked off as unusable.
and when I was talking about putting the staging cassettes on the bottom I meant the lower level going off to the left and right but now i see that if i did that the layout would be too wide.
I am thinking of train lengths of 1 engine, 6 50' cars and caboose. that would mean that my cassettes would have to be about 34" long.
That is true, about the yard location. Considering each of the two designs above (yard on "north" side and yard on "south" side) where would you want to put the staging if you were going to be the one operating it?
I'm not an MRR subscriber so I don't know what the plan looks like. Would you either post a picture/trackplan or explain it to me?
