NLR Class 75
 The North London Railway Class 75 is a class of 0-6-0T steam locomotive.Thirty were built to a design by J.C. Park from 1879 to 1905. They were designed for shunting the NLR's docks and were very compact but powerful engines. This made them suitable later for transfer onto the Cromford and High Peak Railway in Derbyshire and some were sent north. They worked there until they were displaced by J94 Austerity 0-6-0STs.
