4-6-0 Identification Guide
by John Lewis
The
GWR used the 4-6-0 wheel arrangement extensively from Churchward
onwards. Telling the different 4-6-0 loco classes apart is not always
easy in photographs, especially for newcomers to the GWR. Below,
John Lewis provides a quick guide to help such photo identification.
Note: This is meant as a quick guide only, for use with
photographs. It ignores driving wheel diameters as far as possible.
4 cylinder Castle Class No. 5063 "Earl Baldwin"
4-cylinder 4-6-0s
All have characteristic deep slide bars and
inside cylinder covers which protrude beyond the front of the smokebox.
The outside cylinders are placed by the rear bogie wheel. Steam
pipes (where visible) are elbowed.
Stars
Churchward cabs with no side windows. Early ones had angular footplates
and cab bottom at footplate level. Built without steam pipes being
visible. Note: Some rebuilt as Castles.
Castles
Collett cabs with side windows. Inside framed bogies. Elbow steam
pipes.
Kings
Collett cabs with side windows. Half outside framed bogies. Larger
boiler. Elbow steam pipes.
2 cylinder Saint Class, No. 2930 "St Vincent"
2-cylinder 4-6-0s
All the 2-cylinders have characteristic flat looking slide bars and
no inside cylinder covers. The outside cylinders are placed between
the bogie wheels and visible steam pipes are straight. Only inside
framed bogies were used.
Saints
Churchward cabs with no side windows. Early ones had angular footplates
and cab bottom at footplate level. Built without steam pipes being
visible.
Halls
Modernised version of Saints with Churchward cabs and smaller driving
wheels. The footplate over the cylinders was level.
Modified Halls
As earlier Halls, but with plate frames throughout. These show above
the footplate at the front, below the smokebox, but there are no
inside cylinder covers. The bogies on the modified Halls had plate
frames which protrude in front of the leading bogie wheels.
Granges
Effectively Halls with 5ft 8in driving wheels, instead of 6ft. Therefore
raised footplate above the cylinders. Collett type cab.
Manors
Lighter version of Granges with smaller boiler. Difficult to tell
apart from Granges in photos showing the fireman's (left hand) side
if numbers or names not evident. Granges, Halls and Counties had
4 cone injectors which show as a long cover on the boiler side below
the handrail. Manors do not have this feature, but it was
on the driver's (right-hand) side of the locomotive only.
Counties 10xx
Similar in appearance to Modified Halls, but had continuous splashers
over driving wheels, instead of individual ones. Some had double
chimneys. Collett type cab.
