Baldwin built fifty 3400 class Pacific type (4-6-2) locomotives for the AT&SF between 1919 and 1924 (#3400-#3449).
Designed by John Purcell, who became the AT&SF's head of motive power in 1912, they were the last Pacifics bought by the Santa Fe. Purcell brought an end to a period of experimentation by the AT&SF during the early years of the 20th century, which included balanced compounds, "Vauclain accordion flexible smoke box" 2-6-6-2s with hinged boilers, articulated 4-4-6-2s and even ten 2-10-10-2s.
Under Purcell, the Santa Fe started buying large groups of simple, two cylinder locomotives, such as the 4-6-2, 2-8-2 and 2-10-2. They operated on slightly lower than normal boiler pressure and lacked most modern appliances. Purcell believed the added efficiencies offered by such appliances were just not worth the extra maintenance costs.
#3424 was one of a batch of ten 3400s built in 1921 at a cost of $61,927.08 each. For many years, it hauled passenger trains on the Illinois Terminal, Illinois and Missouri Divisions of the Eastern Lines.
