. 2 Withdrawal The reception given by footplate crews was such that more of the class were constructed for other parts of the network, although the electrification of the Southern's Eastern Section meant that they were dispersed from their original stamping grounds.  Withdrawal [ edit ]
2 Bibliography Livery and numbering [ edit ] Southern Railway [ edit ] The class performed well from the outset, but there were a number of minor modifications over the years. The first ten were built without smoke deflectors, but these were added from August 1931,  and the remaining thirty were fitted with them from new. Following the successful introduction of the Lemaître multiple jet blastpipes on to the Lord Nelson class, Maunsell's successor Oliver Bulleid began to fit them to the Schools class.
 However no discernible improvement to draughting was experienced, and only twenty examples were so modified, the most obvious change in their appearance being the large diameter chimney.   Operational use [ edit ] By 1928 the Southern Railway was well served by large 4-6-0 express passenger locomotives, but there was an urgent need for a class to fulfill intermediate roles throughout the system. Maunsell’s previous attempt at developing his predecessor’s L class for this task had proven a disappointment, and the Drummond D15 and L12 classes were approaching the end of their useful lives on these services.
 An entirely new secondary express passenger locomotive was required to operate over the main lines throughout the system including those that had relatively short turntables. Permission was granted for the first batch of fifteen locomotives in March 1928, but this was reduced to ten when it became apparent that they would not immediately be able to operate on the Hastings route. Production delays at Eastleigh railway works meant that they were not delivered until between March and July 1930.
 Once the original batch had proved their worth and had been well received by the crews a further twenty locomotives were ordered in March 1931 for delivery between December 1932 and March 1934. A third batch of twenty were ordered from Eastleigh in March 1932 for delivery after the completion of the previous order, but this was subsequently reduced to ten locomotives because of the continuing trade depression.  The final locomotive in the class was delivered in July 1935.

Lawrence was severely damaged at Cannon Street station, London in a Luftwaffe air raid. 
 Modifications [ edit ]
 The factor of adhesion, unusually, is below the usual design target of 4 although the smoother power delivery of the 3-cylinder layout compensates for this to some extent. Construction history [ edit ]
 Authorities disagree as to whether Maunsell had in mind the restricted loading gauge of the Tonbridge to Hastings line when he designed the class,  or whether this was an "unexpected bonus" when he was forced to substitute a "King Arthur" round-topped firebox to his planned Belpaire design to reduce the axle load on the driving wheels to acceptable limits.  In either event the class was undoubtedly Maunsell’s most immediately successful design, and the locomotives did some of their best work on the Hastings route.
Withdrawals began in January 1961 and the whole class had disappeared from service by December 1962. 2 Post-1948 (nationalisation)
1 Naming the locomotives The original ten locomotives were shared between Dover for use on the South Eastern Main Line and Eastbourne for London expresses. Several of the former later transferred to Ramsgate. By mid 1931 they began to be used on the Hastings services and as more locomotives became available later that year they also appeared on Portsmouth expresses.
After the electrification of the London to Eastbourne and the London to Portsmouth routes in the late 1930s the class also began to be used from Bournemouth.  Under British Railways they were also widely used on cross-country trains from Brighton to Cardiff and Exeter and on the Newhaven Boat Trains. Two locomotives (30902 and 30921) were briefly supplied with Lord Nelson tenders for use on the longer runs of the Western Section.
 Achievements [ edit ]
 To maintain the high power rating required for express passenger engines, Maunsell opted for a three-cylinder design.  In terms of tractive effort, the class was the most powerful 4-4-0 ever built in Britain, and were the only 4-4-0 type to be given the power classification of 5P by British Railways.
 They also had a higher tractive effort than the nominally more powerful King Arthur class 4-6-0s, but at the cost of high axle-loading: 21 long tons (21 t).  The permanent way on the Hastings line therefore had to be upgraded during 1929 and 1930 to accept the new locomotive.  Accidents and incidents [ edit ] The Southern Railway continued its 1923 naming policy for express passenger locomotives with this class.
 As several public schools were located on the Southern Railway network, the locomotives were named after them.  This was another marketing success for both railway and schools concerned, continuing in the tradition of the N15 King Arthur and Lord Nelson classes.
