Wow! Didn't realize I'd touched a piece of history. As a good railroad union brother and Woodie Guthrie fan, I've long had an interest in the Ludlow Massacre. As an adolescent in the late-'50s, I used to sneak rides aboard C&S 646 in the yard at Greeley, courtesy of the crew from Fort Collins. Their befriendment of this lonely kid will be long remembered. The 646, by then an oilborner, had been refitted with a sweeter-sounding whistle off a D&SL loco. Last I saw of her, only the boiler remained next to the roundhouse at Cheyenne, which was then part of a junkyard. That was about 1962.
