General Notes:

a.	Research by locomotive historian Richard Prince suggests that UP 940 was built as Illinois Central number 3 in 1852 and sold to UP as UPRR 53 (2nd) in 1867; builder information shown above reflects that information.

Notes:

1.	UP 938 was purchased second hand by UPED in 1864, named "Delaware", numbered as UPED 2; to KP 2 in 1869; to UPRy 820 in 1885; rebuilt in April 1886; to UP 820 in 1898; to UP 938 in 1915; vacated in 1923 (previous ownership prior to UPED is unclear; previous research by others suggests that UPED 2 was built in 1855 as Lehigh Valley number 5 "Delaware")
2.	UP 939 was built as UPRR 70 in 1868; to UPRy 70 in 1880; to UPRy 339 in 1885; rebuilt to UPRy 824 in 1886; to UP 824 in 1898; to UP 939 in 1915; vacated in 1923
3.	UP 940 was purchased secondhand as UPRR 53 (2nd) in 1867 from contractor Casement, build date unknown; to UPRR 53 (2nd) in 1867, replacing wrecked UPRR 53 (1st); to UPRy 53 in 1880; to UPRy 302 in 1885; rebuilt to UPRy 826 in 1886; to UP 826 in 1898; to shop goat 03196; to UP 940 in 1915; vacated in 1933

General Notes:

UP 941 (as UPRy 827) was possibly rebuilt from a locomotive other than UPRy 402; research by George Pitchard shows that UPRy 402 became Idaho Central 1 in 1887, then OSL&UN 402 in 1889, then to OSL 100 in 1897, citing a U. P. Boston General Office general journal entry in August of 1887, which notes that U.P. engine No. 402 (and some other rolling stock) was sold in that month to the new Idaho Central Railway.

UP 944 and 945 were built in 1887 with Wooten firebox and camelback cab; rebuilt to standard firebox and cab in 1891-1892
