Since it was built in 1914 would it have been a Harriman Standard locomotive?  It looks very simular to SP switchers (other than it being a coal burner).

Yes, it's a Common Standard CS-109 Class, UP Sub Class S-4 4400-4420. It was the last of five in that Sub Class Built by Lima in August 1914.

UP had a total of 303 0-6-0 Switch locomotives.

UP's 303 0-6-0 S-Class switchers were built between 1890 and 1921, in the following series:

• (21) LA&SL 4226-4246 (21)
• (187) UP 4300-4307 (8), 4310-4347 (38), 4350-4480 (131), 4600-4609 (10 USRA)
• (61) OSL 4700-4544 (45), 4748-4752 (5), 4758-4763 (6), 4753-4757 (5 USRA)
• (34) OWRR&N 4900-4933 (34)

The S-51, S-55 and S-56 classes (62 total) were built before the Harriman Common Standard era, built in 1887-1902.The S-1 to S-6 classes (226 total) were the Harriman Common Standard designs, built in 1904-1920.The Special classes (15 total) were USRA design, built in 1918-1919.Retirements for the pre-Harriman era locomotives started as early as 1913. The Harriman era locomotives, built beginning in 1901, were retired starting in 1925 and continued through to 4466's retirement in 1962.

A summary list of all of UP's 0-6-0s is on this web page.
