I have seen both sets and never noticed interior occupants.
K line may have done limited numbers of seated passengers?
RSJB18, you could have a RARE set!
Or hmmm, there might be a possibility that someone altered and inserted seated figures?
Anyway, Let me know if you grow tired of them....lol.
Question: did you wire the MP 15 in series? have you weighted down the MP 15 and FA dummy?
They do look fantastic on the upper level of your layout!
Leroof.
