Cecil Paget, the superintendent of the Midland Railway, had a steam motor locomotive built to his own design in 1908. It had eight uniflow cylinders located between the axles and controlled by a rotating shaft. They drove jackshafts, which in turn acted on three axles. The boiler was also special, having a large diameter and a firebox similar to the Wootten fireboxes used in the United States.

The financing of the locomotive was supposed to come entirely from Paget's private funds, but when these were not sufficient the Midland Railway had to intervene. Although the locomotive was tested on public lines, its existence was kept secret from the public. This was probably also due to the fact that Richard Deeley, locomotive superintendent at the time, did not believe in the success of the locomotive.

During testing, problems arose regularly, which mainly affected the valve gear. The locomotive was stored since 1912 and was no longer tested. It was apparently scrapped in 1918 in Paget's absence when he was in charge of the Railway Operating Division in France. The only known photograph appeared only after the 1923 grouping.
