the piston diameter was marginally decreased from to . The class received bogie tenders from Robert Urie's S15 class and Southern-type smoke deflectors on either side of the smokebox. 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. Naming the locomotives Two of the locomotives retained their original names: number 2333 Remembrance and 2329 Stephenson, whilst the other members of the L class, were newly new named after famous railway engineers. The new locomotive names were suggested by Maunsell's assistant, Harry Holcroft, and were distributed as thus: 2327 Trevithick, 2328 Hackworth, 2329 Stephenson, 2330 Cudworth, 2331 Beattie, 2332 Stroudley, 2333 Remembrance 2333 Remembrance retained its name as it had been the LBSCR's designated memorial to employees lost in the First World War. However the original LBSCR nameplates were straight for water tank mounting, necessitating new rounded plates to fit over the central wheel splashers (see colour plate in infobox above). Operational details 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 of the N15 "King Arthur" class. Once this misconception was overcome, the class came into their own on the Basingstoke services, where their ability to accelerate well was put to good use. However, the rebuilds gained a reputation for rough riding and relatively poor efficiency when compared to the N15s, and were dissimilar in performance to the original L class locomotives, making them unpopular with crews. Because of this, the class was used on secondary duties, cross-country and inter-regional trains around Basingstoke rather than the heavy London to Exeter expresses for which they were intended. Several of the class were loaned to the Great Western Railway between 1942 and 1944 to assist in bolstering freight power, of which there was an acute shortage on that railway during the Second World War. The class saw use after nationalisation in 1948, but with increasing numbers of Bulleid Pacifics able to take over their duties the Remembrance class began to be withdrawn from service during the mid-1950s.
