Boy o boy, so much has changed, i'm starting to feel old. Tower gone, intermodal yard moved, roundhouse gone. I got to see the wheel turning lathe & drop table during a tour of the roundhouse in summer of 1985. It was originally installed at the Nelson diesel shops and used on the F-M units.
I remember exploring all the old CNR trackage that went up to the former Dominion Bridge site between Blackfoot & 26th Ave. Their last contract before closing down the plant was fabricating the bridge sections for the John Fox viaduct for the Rogers Pass Project.
My Mom lived briefly near 18th Ave - 9th St SE about 30 yrs ago. Not sorry to see the Shamrock go, it was pretty seedy, and I've been in the Cecil a few times. heh I've been told the Shamrock was a popular place in the 60's for railroaders and stockmen to get drinks.
I was looking closer at your 1st pic, I've never seen a guard rail off to the outside of the rail like that before.
