When one sees a reference to a 40' boxcar, or 50' boxcar, or 54' covered hopper, is that the INTERIOR length, or the EXTERIOR length. Obviously there could be a big difference, esp. in the case of some covered hoppers.

The reason I started wondering is that I've ended up compiling some stats for some of my railroads, and was curious whether, when a boxcar (etc.) of a specific length is indicated, whether I should be looking at the inside/outside length to compare to, say, Walthers Catalogue.
