Ah OK. I thought Lenz too had it's own protocol. Thanks for clearing that
up.

True... wouldn't even degrade normal operations. While at it, the way the
spring is held in place could be improved too, as well as the spring power
(I've had a few points go bad and always due to spring issues)

Problem is that a train motor can use up to 750 mA and a scenario with say 4
train motors is quite normal (Michael Schian's big trains alone use 3 or
4), I usually have 2 in one engine and I'd certainly like to be able to use
3-4 engines at once (so around 10 motors should be possible) That would
mean around 3 of those units...
Multi "TCX" units sounds nice, but very expensive. One of those should be
enough to handle the logical side... perhaps simple boosters?
As for shorting it : the RCX has some protection, the train controllers are
well protected. So I think something similair could easily be used in a
"TCX"
