The B class are a class of diesel locomotives built by Clyde Engineering, Granville for the Victorian Railways in 1952–1953. Ordered and operated by the Victorian Railways, they initiated the dieselisation of the system and saw use on both passenger and freight services, with many remaining in service today, both in preserved and revenue service. Some were rebuilt as the V/Line A class, while others have been scrapped.
