Introduced in 1863 by Mr. Ramsbottom, this small four-wheeled
saddle tank was used for shunting . They
were the first class to have
cast-iron H-section spoke driving wheels , later
fitted by Mr. Webb to most goods classes. The chimney had an ornamental
cap and there was no cab, simply a spectacle plate .
Both buffer beams and brake blocks
were of wood. Curiously the right-hand cab side sheet was continuous
and raised so coal could be stored at that side, there being no
bunker in this rudimentary design. Even stranger there was a step
and handrail at the side you could not enter, used by shunting staff
to ‘get a ride’ on the engine.
The Ramsbottom safety
valves had a long lever you could ‘knock off’ but no
cover around the spring to prevent tampering by the enginemen —
if they could increase the pressure power would be raised, but at
risk the boiler could explode catastrophically!
Ten more were built in 1892 (29 years later!), three being
finished as 0-4-2T crane tanks.
