I am not certain, but I’m pretty sure that these ridgie, corrugated stainless steel cars are from the 60’s. I recall them from when I was quite young. Then again, I also have memories of cars in the 70’s that seemed to have been relics of the 30’s and 40’s – white enamel hand loops, small ceiling and wall fans, and wicker seats. Was this just a byproduct of too many hallucinogens? A trans-dimensional shift? An over-active imagination?
I don’t think so.
Either way, these cars have to be some of the oldest ones on the line at the moment, but I think they are holding up well from an aesthetic standpoint.
