I am getting ready to install a crossing at grade with another railroad and will have an interlocking tower. Plans are to detail the with non-working rodding to signals and one switch and lock. I am familiar with prototype systems but haven't had much luck finding US-style detail parts in HO. I have found a few suppliers in the UK but they use square piping and the pipe and bellcrank stands are not US design. I could possibly use the bellcranks from UK but would have to scratch the other fittings. I would rather not have to mess with ordering from overseas. 

I'm sure some have used them or else they wouldn't be offered.  Not talking about turnouts, nor the kits, but the strips themselves.  I recently bought a bunch for my expansion, and some rail, then the thought occurred to me today......er ah um, and just why exactly didn't you just use flex?

......well, in any event, I got a bunch of CVT tie strips coming and I know I'll use them.  Any left-overs can easily be used for an outdoor sunlit diorama for photos and stuff.
