Why? Don't you just need a way to stop the monorail under RCX control? That
requires a reliable motorized reverser/stop control track it seems to me...
(I have been tinkering but don't have a good design yet, the thing you pivot
is very stiff and I have sheared some axles trying to do it.
Or were you tinking that you'd send the faster monorail on a longer path if
sensors indicated it was catching up too much? That would be a VERY neat and
novel approach.
