700 and
C8 classes
Construction history
40 of the class were subsequently outshopped from the LSWR's Nine Elms locomotive works. They were generally paired with a 6-wheel tender because of their intended short journey lengths, which included local stopping trains and medium-level freight haulage, but as with the later
L11 class, some could occasionally be seen with a 4000 gallon "watercart" tender for longer trips.

Livery under the LSWR was Drummond's LSWR Passenger Sage Green, with purple-brown edging and black and white lining. Under
Southern Railway ownership from grouping in 1923, the locomotives were outshopped in
Richard Maunsell 's darker version of the LSWR Sage Green with yellow lettering on the...
