Hello all,

I think that maybe 4 years ago there was a request for design suggestions on a
wheel rim inspection system for rail car wheels in the USA. I believe the
specification required that the system be capable of performing the inspection
on a slow "roll by" of the rail car (2-3 miles per hour). I don't remember if
this was in Mat'l Eval or in an NTIAC newsletter.

Casually, at the time, I assumed that an electromagnetic test would be the
likely method for this application. Apparently UT is more common, at least in
Germany. Does anyone remeber the request for quotation that was published a
few years ago? If so, do they know who secured the contract and what method
they utilized for the inspection? I have no vested interest in this, I am
merely curious.

Tom
