I’ve rode behind Alcos on the A&M in AR and I now know why they are called the steam engine of diesels. It was part of a private charter by Southern Appalachia RR Museum and when the director called for more some on the photo runbys, he got it.
I have friends who do volunteer work with that RR and the Alcos just keep ticking along. And I’ve seen pictures that others have taken of Alcos at work all over the US and many times, they are really smoking.
Long live Alcos.
