The GWR Manor was a versatile 4-6-0 configured locomotive designed with a lighter axle loading than the existing and popular Grange class 
which enabled the Manor to operate in regions of the GWR where this was not possible with a locomotive of comparable power. In all, 30 
Manor class locomotives were manufactured at Swindon in two batches: 20 between 1938 and 1939 and then a further 10 post nationalisation 
in 1950 which were designated 5MT. Although initially the performance of the locomotive was deemed at best mediocre, subtle internal 
refinements made towards the mid 1950s resulted in a successful and popular locomotive. In all nine examples of the Manor survived into 
preservation.
