John, the NMRA recently finally approved and aopted the NASG S-3 and S-4 Standards, but these only affect wheel and track standards. I don't think S-7 was in contention. As far as I know, all agree that H, the rail to top is 22' or 4 1/8". I had an old clearance gauge that had a width of 15' but in 1998 I made up a new one with a width of 16'. I can't remember what source I used for those width dimensions but I seem to remember it was for modern cars. In any case the 22' was used in both gauges. I haven't seen any updates although my guess is the prototype double stacks need more than 22' clearance. Unless you are modelling modern stuff I think 22' is safe but hopefully one of the technical guys can be more positive on this. Wally Collins
