Soon after the grouping the need arose for an express passenger locomotive capable of working a 500-ton train on the Southern Railway at an average speed of 55 mph. It was not until 1926, however, that Maunsell was able to produce an engine that answered these requirements. When it did appear it was in the form of a 4-cylinder 4-6-0, No. 850 ‘Lord Nelson’. It was thoroughly tried out before any more were put in hand, but eventually fifteen more came out in 1928-9, No. 851-65, all named after famous sea lords. They worked mainly on the Continental expresses between Victoria and Dover and were very capable machines.
A peculiarity lay in the setting of the angles of the cranks by which the engine gave eight exhausts per revolution of the driving wheels instead of four, resulting in a very soft blast and even torque. The arrangement had already been tried out experimentally on one of Drummond’s early 4-6-0s. and was anticipated in the first place in Hookham’s 0-6-0T for the North Stafford Railway. One or two of the engines varied slightly, No. 859 had 4” smaller driving wheels, No. 960 a longer boiler barrel, and No. 857 carried for a time an experimental boiler with a combustion chamber, while No. 865 had the conventional 4-beat crank setting. They were handsome engines as built, but were later fitted with an ugly wide design of chimney to accommodate a double blast pipe, which completely ruined their appearance. All were still in service in 1959 as Nos. 30850-65.

2113 - B14No. 2113 of the 6’ 8¼” class running in early days.  Both classes were very little altered during their existence.

These engines were notable as being the first passenger engines of the 4-6-0 wheel arrangement in this country, a type which was to become almost universal in later years on most larger Companies for main line passenger service.  The first ten engines, Nos. 2001-10, turned out in 1899 and 1900, had coupled wheels of 6’ 1¼” diameter, and although considered on the small side in those days for express working, they showed themselves capable of a fair turn of speed.  Nevertheless five similar engines, but with 6’ 8¼” wheels came out in 1901, numbered 2111-15.  A further thirty of the 6’ 1¼” variety came out in 1906-9, all except one carrying numbers between 726 and 775, the odd one being No. 1077.  These later engines differed slightly from the earlier ones in having much thicker framing over the driving wheels, and smaller splashers.

Although designed as express passenger engines, the 6’ 1¼” class did not do a great deal of this class of work, and they very soon took second place to the R Class 4-4-0s and later the Atlantics.  Latterly they were used principally on express freight traffic.  They were taken out of service between 1928 and 1938, but No.761 was retained for use as a dummy counter-pressure engine in conducting tests at Darlington (and later at Rugby) works, and was not scrapped until 1951.  Since 1946 it had been No.1699.  The 6’ 8¼” engines disappeared between 1929 and 1931; they were extremely handsome machines, but for some reason never seemed to appear much in the limelight.
