The RCX is often used as a very expensive and overengineered way to solve
simple problems. Sure... I *could* try that approach. But I'd rather do it
mechanically. And $200 (or thereabouts) for a relay would cut very deeply
into my Lego budget.

That would be cool, though too complex for a mechanical solution (at least
for me at this time). And I misspoke when I said "point". I really did
mean the reverser track. I'll probably start with a design much like my
Duplo relay and go from there. I'm thinking of having one train stop at the
station while the other goes around the track. As it approaches the
station, the first train takes off.
Motorized switches come next- Will Chapman showed my his design a while back
that he claims is quite reliable, though it might not work for my purposes.
If only Lego would sell the polarity switches again- that would make this
job *far* easier. I have to find really wacky solutions to work around this.
