4-2-2 Class 115 "Spinner" MR Profile and Models

The Midland Railway 115 Class was the third of four classes of 4-2-2 steam locomotive, nicknamed "Spinners", designed by Samuel Waite Johnson. A total of 15 of the class were built between 1896 and 1899. They were capable of reaching speeds of up to 90 miles per hour. Single-driver locomotives had been superseded in the late 19th century as loads increased, but were then reintroduced when steam sanding allowed better adhesion. It was quite common for this engines of this class to pull a typical Midland express weighing 200–250 long tons, which suited the Class 115 perfectly. Speeds up to 90 mph were not uncommon, and the sight of their large, spinning driving wheels with no visible connecting rods, like a spinning wheel, earned them the nickname "Spinners". No. 673 is the sole survivor of its class. It was steamed around 1976–1980 when it took part in the Rainhill Trials 150th cavalcade but is currently a static exhibit in the National Railway Museum in York.
