In 1901/2 Dugald Drummond introduced the K10 class (or
"Small Hoppers"), a class of 40 4-4-0s which shared the same
cylinders, boiler and firebox as his first 4-4-0 for the LSWR, the C8
class of 1897, although with 40 2¾ inch water tubes the K10's
heating surface was greater. The frame length and wheelbase were identical, but
with smaller wheels as they were intended for mixed traffic duties, though they
shared the same problem as the C8s, an inability to sustain their power, which
led to them having only occasional main line use. This defect did not, however,
prevent them having an exemplary career on secondary routes as the LSWR had few
heavy goods services that would have taxed them to the limit. N°137,
built in September 1902, was the 650th engine to be built at Nine Elms. The
class was never superheated, which might have improved their steaming.
The water tubes in the firebox did not last long as Urie began removing them quite early in his career. Normally coupled to a standard Drummond 14 foot tender, seven were allocated his 4,000 gallon bogie tenders which, rather than remain with the same locomotive, tended to be switched around within the class, though 135, 144, 380, 382, 386, 391 and 392 seem to have been the main users. After the grouping of 1923 the Southern Railway sent ten of the class to work on the former SECR lines where they were fitted with Urie stovepipe chimneys. They later returned to ex-LWSR lines though some of these ten locos were occasionally sent to Ashford for repairs. One, N°140, had its Drummond chimney restored. Wartime service saw a few of the locos on foreign metals. In 1941 one loco was lent to the War Department, returning in 1942, whilst five others were lent to the LMSR for working their section of the Somerset & Dorset line then in August 1942 two of these five were at Gloucester and one at Bristol. They then moved to Nottingham until December 1944 whilst the remaining two of the original five spent the latter part of the war at Bristol, returning to the Southern in March 1945. Withdrawals started in january 1947 and although the majority of the class saw service with British Railways, it was not for long with the last one withdrawn by July 1951. |

The L&SWR was better than the other Southern Companies in keeping locomotive classes more or less in consecutive numbers, though not perfect! The following table is set out in order of build: | |||||

# | Between 1923 and 1928 SR numbers were the L&SWR numbers with the added prefix 'E', although the prefix may not have been removed until some time later! | ||||
* | It is highly unlikely that the locos withdrawn in the very early days of British Railways carried a smokebox number. | ||||
Ø | Sent to the ex-SECR section and fitted with Urie stovepipe chimneys after the grouping, but all returned before nationalisation. 140 had Drummond chimney restored in Jan 1946. | ||||
§ | Lent to LMSR in 1941. 135 at Bristol and 137 & 138 at Gloucester in Aug 1942. All three later at Nottingham until they returned to the SR in Dec 1944. | ||||
¶ | Lent to LMSR in 1941. Both later at Bristol until they returned to the SR in Mar 1945. | ||||
µ | Lent to the War Department in 1941. Returned to the SR in 1942. |
