I rode them a couple of times in 1960 going to university in Minneapolis on the
Mountaineer. I was a beautiful coach with the etched glass divider to provide a
smoking area. Robert Sandusky has a nice picture of the much abbreviated
Mountaineer in May 1960. Alas the Mountaineer was gone by fall of '61.
BTW I have a Northwest resin kit for sale. Contact me off-line if interested.
I only wish I could have ridden them.
