Switches and sidings allow other trains to
pass. Trains can be reconfigured on one of the two sidings or wait for another train to go
by. This section encourages cooperative play with other engineers at the table.This
module could be made flat, but adding a half-ramp up and/or down for the sidings makes it
even more interesting. You may need to make a few trim cuts to avoid gaps around the
double crossovers. Still an easy first effort.
