John Nehrich asked:

I've just been studying the Red Caboose's web site for their PFE reefers.
Maybe I've missed something, but I don't see any explanation of the "TW"
designation. Is this something they made up for non-PFE cars?

John, you can look up the AAR type designations in the back of any ORER.
