 The NSR also used a small number of railmotors with three being purchased in 1905 from Beyer , Peacock and Company . They were used on routes such as the Stoke – Newcastle service but were not a success . The vehicles did survive until grouping but had been taken out of service for some time some years earlier . In addition to the NSR locomotives were the two engines of the Leek & Manifold and the three engines that worked the Caldon Low quarries . The former were purchased from Kitson and Company and the latter from Henry Hughes and W. G. Bagnall .
