The Midland Railway 115 Class is a class of 4-2-2 steam locomotive, nicknamed “Spinners”. They were designed by Samuel W. Johnson and a total of 15 of the class were built between 1896 and 1899. It was quite common for this class of engine to pull a typical Midland express weighing between 200 and 250 long tons which suited the Class 115 perfectly. Given a dry rail they could maintain a tight schedule with 350 long tons. Speeds up to 90 mph were not uncommon and the sight of their whirring huge driving wheels earned them the nickname “Spinners”. Thanks to the Midland’s practice of building low powered locomotives and relying on double-heading to cope with heavier trains many enjoyed working lives of up to 30 years. They made ideal pilot engines for the later Johnson/Deeley 4-4-0 classes. Sadly this engine, which had been gathering dust in the old round house at Derby Works when it was drawn in 1950’s is no more, but a sister (No. 673) also built in 1897 can be seen at the National Railway Museum (Station Hall) at York, England.
