The Grand Trunk Western received five U-1cs from Baldwin in 1925, which were similar to parent company Canadian National's U-1a and b. They were modern Mountain type locomotives that were suitable for passenger, express and freight trains. They had a feed water heater and a stoker and were the first GTW locomotives with a Vanderbilt tender. Beginning in 1929, the CLC delivered five U-1d and the Montreal Locomotive Works twelve U-1e. The sub-variants d and e are largely the same, but differ in the Walschaert and Baker type valve gear.
