On these two units I have, there is only the LD LMT, no LT WT. That is why I asked. IN teh prototype ones I looked at as well, it was all Load Limit.
RexHea, I use a prototype switch list that I got off a shortline in Oregon, the Central Oregon & Pacific (CORP). It lists the total length and weight, loaded or unloaded, at a stop. I'll have to post it up here after I refind it.
