Our little indoor layout (four 5’ X 2.5’ tables) looks like this:
We’ve done a couple of ops on this layout, as follows: 1) Rearrange cars from start positions to finish positions on various sidings. 2) Make up a train in a specific order. So far, the longest we’ve managed is eight cars, and that took some thinking through! We use a little USA 20-tonner, partly because the curves are tight, partly because our little LGB transformer/controller can handle it.
Start point is always the boom gates. Sometimes we put the prime mover across the tracks, to add a bit of spice to the exercise. If we forget to move it before the train pulls in . . . .
The train often runs close to the edge of the table. Bad place to derail, so we keep the speed down.
Occasionally we add in some ops with the battery-powered crane. Our grandsons love it!
There’s often very little clearance between the cars.
There’s a switch in the tunnel, which explains the oversize portal.
Finding the optimal sequence of steps to make up the train can be a very interesting challenge!
