Directors were still not convinced that the extra building costs associated with superheating was matched by lower running costs. Marsh therefore built four more superheated

February 1909 and March 1910. By mid 1910, there was sufficient operating data to convince the Directors and all after this date were superheated. Five more locomotives appeared in 1910.

The first ten were numbered 21-30 and the remainder 75-91. The
Southern Railway initially added a "B" prefix to these numbers and later renumbered them 2021-2030 and 2075-2091. BR added 30000 to the numbers.

Both varieties of the I3 class proved themselves to be excellent locomotives but the superheated versions were significantly cheaper to run on express trains, especially when compared with the
