The 3500/3600 Class were built for QR's coal networks. The 3500 series locomotives were "control" units, whilst those numbered in the 3600 series were "slave" units.
A number of 3900 Class locomotives were absorbed into the class from 2003, numbered from 3551 to 3573. After this upgrade, the remainder of the 3500/3600 Class locomotives were similarily updated, resulting in the class being known as the "3551 Class", despite the lower numbered locomotives originally built. Eventually the slave units were converted to control units, and given the appropriate number in the 3500 series. All are included here for completeness.
