ZTC (in that order?) However, purely out of interest, I wonder if anyone
might know what the equivalent- sellers in the US are?
I assume that Lenz and Digitrax have a presence (but probably not ZTC)- any
others? Which is the most widely- used system? Also, if there is a system
out there that I have not mentioned, is it available here in the UK?
Purely out of interest and comparison's sake, that's all.
