The Grange class - the missing link

South Wales was blessed by the presence of Barry Scrapyard to
where hundreds of steam locomotives were sent for cutting up at the
end of steam in the 1960s. Fortunately, because the yard was
preoccupied with other matters, few were actually scrapped and
preservation groups started buying the rusting hulks for
preservation. Because the yard was in South Wales, a large
proportion of the stock was of Great Western or BR(W) origin so
today, the Great Western is very well represented by the number of
locomotives that survive.
Most GWR classes still working in the 1960s are represented by
those that survived but there were a very few notable omissions -
and among them are the Collett 6800 Grange class 4-6-0s, of which
80 were built, and the Hawksworth County class 4-6-0s.
The Granges are perhaps the most lamented of the 'missing'
classes. They were good looking locomotives, with a
distinctive raised section of the running plate over the
cylinders. They were powerful, free-steaming engines and were
popular amongst crews - they were often termed the 'engineman's
engine'.
Fortunately, the omission is being rectified - the 81st Grange
is being built at Llangollen, no. 6880 Betton Grange and you can
find out more of this project by visiting the Betton Grange
website. The locomotive incorporates parts common to
other locomotives which is entirely in keeping with the Great
Western Railway's standardisation policy. For example, the Swindon
No. 1 boiler have been donated by Modified Hall class 4-6-0 no.
7927 Willington Hall (the frames of that locomotive are,
incidentally, being incorporated into a new-build County 4-6-0 at
Didcot Railway Centre, plugging another Great Western gap).
The Betton Grange group regularly visit the Gloucestershire
Warwickshire Railway with their information and sales stand at the
annual Cotswold Festival of Steam. They have also promised
that when their locomotive is complete, it will visit Toddington
and can take on the identity of one of the last of the class to
survive, no. 6848 Toddington Grange - a magnificent picture of
which adorns the fireplace in the Flag & Whistle at Toddington
station.
History
The picture of no. 6823 Oakley Grange approaching Bishops Cleeve
in 1962, taken by the late Bill Potter and submitted to the website
by Bernie Holland, is a reminder of what we are missing. The
purposeful yet graceful appearance of these engines is difficult to
beat. So how did the class come about?
The 6800 class had driving wheels of 5ft 8in diameter - four
inches smaller than those of the Hall class. However, their
cylinders were of the same size and the two classes shared the
Swindon No. 1 boiler. They thus enjoyed a tractive effort
1,600lb greater than the Hall.
It's interesting to note that G J Chruchward had proposed a
4-6-0 of these proportions soon after he took office as CME of the
Great Western Railway. The intention was to replace the
ageing 4300 class 2-6-0s and indeed refurbished parts of this class
were incorporated into the Grange, in particular the wheelsets and
motion. However, it was not until 1936 that Collett built the
first of the class and 80 had been completed by the time the second
world war broke out. After hostilities ceased, the emphasis at
Swindon had changed and the work was never resumed. Apart
from the early members of the class, the locomotives were fitted
with a smaller-diameter copper -capped chimney which helped to
promote good draughting and free steaming.
The first to be withdrawn was in 1963 but the last four were:
6847 Tidmarsh Grange, 6848 Toddington Grange and 6849 Walton Grange
and 6872 Crawley Grange, in December 1965. 6847's last allocation
was Worcester; the others were withdrawn from Oxford.
It is worth noting that the Manor class was designed as a
lightweight version of the Grange - the most notable visual
similarity being the raised running plate over the cylinders.
Like the Grange, the Manors used reconditioned wheels and motion
from withdrawn 43xx 2-6-0s but the design incorporated cylinders
with a half-inch narrower bore, reducing the overall width of the
locomotive. A 'lightweight' boiler was also developed, designated
Swindon no. 14, which is smaller than the No. 1 boiler used on the
Grange and Hall classes. Overall this produced a weight
saving of about 5 tons and with the narrower overall width, gave
the glass a wider 'Blue' route availability yet retaining a power
classification of D (GWR) or 5MT (BR).
