The 65 class H1a to H1e locomotives were built for use with express and freight trains. Starting with the H1c, they received partial streamlined fairing. After King George VI's train was hauled by an H1d on his visit to Canada in 1939, all streamlined Hudsons officially earned themselves the name “Royal Hudson”. The five H1e built in 1940 finally had oil firing. They were replaced by diesel locomotives by 1960 and some continued to run excursion trips for a longer period of time.
