what is it?

The Great Central Railway Class 11B was a class of 40 4-4-0 express passenger locomotives, designed John G. Robinson. Built from 1901 to 1903, in later rebuilt form as 11D, some 11Bs would last in service until 1950. Railwaymen continued to refer to the class as "11B", even after all were rebuilt to 11D. Being contemporary with and to some extent the 4-4-0 version of Robinson's much more numerous 0-6-0 goods class 9J, which were known as "Pom-Poms", the 11Bs acquired the nickname "Pom-Pom Bogies".
