 After the C-class locomotives came the famous K-class 4-8-4s, of which class leader K 900 became rather well known for its most public departure from the workshops in November 1932.The last steam locomotives to be produced at Hutt were Ka class locomotives 958 and 959 in 1950, though maintenance work on them continued into the mid-1960s.From the 1930s until the 1980s Hutt Workshops had responsibility for assembling then maintaining Wellington's fleet of electric locomotives.
