After the comparative trials, the 3-cylinder compound  was
chosen as the standard heavy goods engine and 110 were built between
1894 and 1900. Steam was used first in the two 15in diameter
outside cylinders, attractively flaired-in by an extended smokebox
wrapper plate , then used again in a single 30in diameter low
pressure cylinder before exhausting to atmosphere up the chimney.
From the front the smokebox profile was reminiscent of a bell shape.
The long boiler enclosed a front tube plate
recessed into the boiler as a combustion chamber .
Sandboxes were provided both at the front of the engine, on the
first splasher , and on the tender front. Sand for the tender could
assist braking or when running in reverse, such as moving off a main
line to allow a passenger train to pass. The third pair of driving
wheels had no flanges , to assist the long rigid wheelbase get round
sharp curves. All were later rebuilt, mostly ending up as
‘G1’ class .
