 Maunsell ’ ' s successor, Oliver Bulleid, oversaw the building of twenty members of the class at Eastleigh railway works between January 1938 and September 1939. Bulleid is reported to have found the Q Class uninspiring, having been manufactured to traditional Victorian principles of locomotive design, and is said to have stated that the order for the Q Class would have been cancelled if he had been appointed CME earlier. However, Bulleid had ample opportunity either to cancel the order or to build and test a single prototype, without incurring the expense of building twenty members of the class, if this was the case.
