Rio Grande's (and later SP and UP's) Burnham shops were located quite close to Denver. UP closed the shop on February 14, 2016. Rumor has it that in 1996, UP made a deal with then Colorado governor Roy Romer, agreeing to keep the shop open for 20 years in exchange for Colorado not objecting to UP mothballing Tennessee Pass the following year in 1997.
The shops had a turntable that was still in use right up until the shops closed. The shops predate the 8th Avenue viaduct which, when built, had to be built around the south end of the main shops.
