what is it?

The LSWR/SR H15 class was a class of 2-cylinder 4-6-0 steam locomotives designed by Robert Urie for mixed-traffic duties on the LSWR. Further batches were constructed by Richard Maunsell for the Southern Railway after 1923. They were given the nickname of "Junior King Arthur" due to the size of their driving wheels, with those on the S15 and their N15 counterparts being 5 ft 7 in (1.70 m) and 6 ft 7 in (2.01 m) diameters respectively.
