Global InformationBR Caprotti Black Fives information
British Railways built twenty locomotives of the LMS Stanier Black Five type, fitted with Caprotti valve gear, in 1948; the BR Caprotti Black Fives. These were numbered 44738-57, 44686 and 44687. The Black Fives had been fitted with Walschaerts valve gear as standard. In 1947, as part of an experimental programme by George Ivatt to try to improve the already good design, (4)4767 was built with Stephenson link motion.[1] The Caprotti-fitted Black Fives were part of the same programme.
