59579Re: AZL latching couplers
- Jan 27, 2009I seem to recall that modern freight cars especially high capacity
cars now run on 36 inch wheel sets rather than the older 33 inch
ones. MTL's I think represent 33 inch size. Could it be that AZL is
representing 36 inch as used on modern cars with roller bearing
trucks. Having said that I think there are some enclosed auto racks
that run on 30 inch or 28 inch wheels. Be interesting to see what the
match is to prototype. There is more than one length for freight
trucks as I recall.
