Grand Trunk Western 5632 is a class K-4-b 4-6-2 "Pacific" type steam locomotive built by the Baldwin Locomotive Works in November 1929 for the Grand Trunk Western Railroad.

History

Construction and revenue service

No. 5632 was one of three K-4-b class 4-6-2's (Nos. 5632-5634) constructed by the Baldwin Locomotive Works of Eddystone, Pennsylvania in November 1929, and it was delivered to the Grand Trunk Western Railroad (GTW) in 1930. The K-4-b locomotives were copies of the United States Railroad Administration's (USRA) Light Pacific design, and they were follow-ups to the GTW's K-4-a class (Nos. 5627-5631).

The only difference from the USRA design is that the K-4-b class was equipped with an all-weather vestibule cab and an enclosed coffin feedwater heater. The GTW ordered the K-4-b's from Baldwin to use them for their sleeper trains—the Chicago Express and the Detroit Express—between Chicago, Illinois and Detroit, Michigan, in competition with the Michigan Central (MC), but both trains were quickly discontinued, due to challenges from the Great Depression.

No. 5632 was subsequently reassigned to pull regular passenger trains between Chicago, Detroit, and Port Huron alongside the K-4-a's. After the GTW received new U-3-b class 4-8-4 locomotives in 1942, No. 5632 was reassigned again to pull commuter trains between Detroit and Muskegon. The locomotive last operated for the GTW in June 1958 before it was put into storage.

Retirement

In August 1960, No. 5632 was donated to the city of Durand, Michigan, where it was placed on static display the following year. No. 5632 is the only surviving member of the K-4-b class, and it is the only surviving copy of the USRA Light Pacific locomotives after GTW K-4-a class No. 5629 was scrapped in July 1987.
