Thanks for posting the photos Jeff and Jerry. I have had the pleasure of riding the 0402 up at Knotts but it was before you put in the cupola cushions. Those boards were hard!
I also had the pleasure of riding the 0500 on the Cascade Canyon train a few years back when I was the only rider - had it all to myself behind my favorite K28, 476, on a full moonlit night. Awesome! This car also has the footwells. I think they were late additions to these cars, modified for crew comfort.
I rode the 0579 on the 315 trains last year. I'm really glad to see these shorties restored.
