The first 4-8-4 was built by the American Lococmotive Company "Alco" in January,1927, for the Northern Pacific. this locomotive was basically the 4-8-2 modified to accommodate a larger grate area and very deep firebox which was required to burn the very low grade of bituminous coal that the Northern Pacific produced from its own mines. this new wheel arrangement was dubbed "Northern Pacific", which was quickly shortened to "Northern".

Some railroads, paricularly the southern ones, rejected the "Northern" name and used Names With regional connections. Like "Greenbriers", "Poconos", "Wyoming","Dixies", Niagras", "Golden State", "Potomacs", Confederations", Mexico called them Niagras", and some 4-8-4 named after southern generals,governors, and statesmen.

The Union Pacific bought all three orders of 4-8-4 from the American locomotive Company. UP No.833 was built in 1939 during the second order of 15 locomotives. No. 833 was designated as Cass FEF-2 and came with 80" drivers. The first order of locomotives came with 77" drivers.
