I stumbled across a photo of a Western Maryland 40' boxcar from 1973 that appeared to still have a pair of Andrews trucks under it. http://www.rr-fallenflags.org/wm/wm28773akg.jpg Can anybody confirm this, photo somewhat dark, but I made a brightness adjustment on Photoshop and it appears to have Andrews trucks on it. Pretty rare on interchange equipment in '73 isn't it?
