Greetings all.
This is purely a selfish question for me (I model June 1991), but maybe you can pretend it is a fun contest. What is the latest date - that you have or that you know of - of a photograph of a non-fully enclosed autorack (such as CTTX or TTBX) in revenue service? I have September 1st 1990, Enola, p. 172 of Withers’ CR Motive Power Review 1986-1991. I’d like to get into summer 1991 if I could.
