The MGR system utilised specific hopper wagons that could be automatically loaded and unloaded. A locomotive fitted with slow speed control could deliver a number of wagons on a continuous loop from colliery to power station delivering coal, hence the adoption of the term MGR to describe this 'merry-go-round' process. The reduction in time and manpower made for a very efficient system with obvious cost savings. It has been estimated that under the MGR system, each hopper could deliver up to 14 times as much coal as a wagon operated under the previous manual system.
