That is a problem, as I noted above in regard to O27 switches. Not sure why they were designed with that pilot truck in front because the original 520 operated with that wheelset as a trailing truck so it actually guides the trailing cars. Hopefully, RMT will correct that if/when they make the things again.
Might be easy enough to correct, as I recall, if the cab figures are simply installed in the opposite end cab. I'm not certain about that though because it has been a while since I fussed with the boxcabs I have.
