[edit] Overview
The class was originally numbered 687–716 but the year after delivery numbers 702–716 were given new numbers vacated by engines that had previously been withdrawn. They gained the nick name 'Black Motor' early in there career, the locomotives were well designed and had little major modifications during the existence of the fleet, the exception being fitted with superheating from 1919 to 1929, which required the fitting of an extended smokebox. They shared many standard parts with Mr Drummond's other designs including boilers with the M7 class.
