It was renumbered 1735 in 1907, and renumbered again in 1912 as 4335. Like most of the Milwaukee Road's Vaulclain compounds, it was rebuilt as a two-cylinder simple locomotive; for 4335 this happened in February 1920 when it was reclassified as class G8 and renumbered 2604. In the Milwaukee Road's 1938 renumbering, it received its last number — 1004. It was finally retired in April 1957.[1]
The locomotive was mostly a freight locomotive while working on the Milwaukee Road; A Railroad article from around 1957 believed that Milwaukee Road 1004 was the last steam locomotive to retire and leave the system.
Today the 1004 is preserved non-operational at the Fairgrounds, in Austin, Minnesota. It is also the only surviving member of its class, and it is one of only six surviving Milwaukee Road steam locomotives.[2][3]
