 No part of the Leader design was perpetuated on the British Railways Standard class locomotives by Robert Riddles, nor did it find favour internationally, with the Garratt articulated locomotives providing a similar function for less maintenance.The whole concept was quietly dropped in 1951 after Bulleid left British Railways to become Chief Mechanical Engineer of Córas Iompair Éireann (where he produced CIÉ No.CC1, a peat-burning locomotive to a similar design) and all five were scrapped.
