559:, and more particularly their small (8 in or 203 mm) piston valves in relation to their large (21 in or 533 mm) cylinders were a significant limitation, precluding their use on any other part of the Southern system. The limited coal and water capacity also limited their range, though adequate for the short runs on the Brighton line. The decision was taken to rebuild them into more conventional 4-6-0 tender locomotives.
580:. At the same time there was a revision of the locomotives' front end arrangement incorporating a "King Arthur" N15 type of blast pipe and chimney; boiler pressure was increased to 180 psi (1.24 MPa), whilst the piston diameter was marginally decreased from 22 in (559 mm) to 21 in (533 mm).

The rebuilding caused a certain amount of controversy among footplate crews, with some maintaining that one could not make so many changes and have a reliable locomotive at the end of the process. The class suffered on the South
Western section from the expectation that they were an improved version

In their new form the locomotives were similar in outline to the N15 class, though suffered from the expectation amongst crews that they were an improved version of this type. Despite this, their ability to accelerate well was put to good use on cross-country trains between main lines. The class saw

After nationalisation in 1948, the locomotives' initial livery was a slightly modified
Southern Malachite Green livery, where "British Railways" replaced "Southern" in "Sunshine Yellow" lettering on the tender sides. From 1949, the class was turned out in British Railways mixed-traffic black livery
754:
Under
Southern ownership, the "Remembrances" were originally painted in Maunsell's Olive Green livery as seen above, with "Southern" and the locomotive's number on the tender tank. Wartime service under the Southern saw the locomotives painted in black livery with "Sunshine Yellow" lettering.

In the early 1930s, with the impending electrification of the
Southern Railway's Central Section (the former LB&SCR lines), the question arose as to what to do with the relatively new and powerful LB&SCR designs. Maunsell looked at the possibility of converting the
595:. The result was classified N15X, the suffix corresponding to the old LBSCR designation for a rebuilt/modified locomotive. The conversion process created a locomotive that was similar in appearance to the N15 "King Arthur" class as modified by Maunsell in the 1920s.

Baltics had proved to be capable machines on the Brighton line, although their relatively low boiler pressure (170 psi or 1.17 MPa), the excessive difference between "first valve" and "second valve" on the
