Somehow (probably because of the USRA pics of switchers), I’ve been caught up with pics of yard switchers – steam era.
This is the Milwaukee Railroad yard:
If you like UP steam, this is a great site: https://donstrack.smugmug.com/UtahRails/Union-Pacific/UP-Steam-Locomotives/ . I found this UP switcher along with a few others:
Same website – this is likely a USRA 0-6-0 (the “US” on the tender):
A PRR 0-8-0 pulling yard duty:
PRR (B8 class) 0-6-0 switcher steam engine #1109 and slopeback tender was built 1910-1911 at the Altoona PA shops. Photo was taken in the Long Island City yard in 1946.
This is an SP switcher at the Bayshore engine house in San Francisco. Apparently, SP (along with several other RRs) had a few of these that they used in engine facilities. (Maybe we need one at the Van Wert roundhouse!)
This one is lettered for “Taylor Round House” – couldn’t find anything on it. (Shrouding/streamlining on a shop switcher(??))
New Haven switcher at Cedar Hill yard, New Haven, CT, 1946:
Maryland & Pennsylvania 0-6-0 switcher, built in 1903, at the Baltimore Roundhouse. (An Armstrong turntable!)
The Davenport 0-4-0 yard switcher was fireless – built in 1953. I finally have some additional info, ”Rather than burning coal or wood to produce steam, the locomotive’s distinctive wide steam chamber was ‘recharged’ with steam from the power plant’s boilers. The process could last up to an hour and, when complete, brought the pressure in the steam chamber up to as much as 625 psi. Each “recharge” lasted roughly 4 hours. Because of the shape of its steam chamber, this 60-ton locomotive was nicknamed the ‘thermos’.”
I’m not very wordy today (Dan appreciates that!). Part is due to the topic – the pic captions, if there is one, are small with very little info. I guess yard switchers don’t attract the same level of attention as large or streamlined steam. The other part is – it’s cold on April 1st!
