Hughes, Geoffrey. Thompson's
1,000 engines. Steam Days, . (28) 18?-23.
Thompson's initial proposal to the Locomotive Committee was for "ten
engines of two-cylinder type, entirely composed of standard parts
which will be roughly equivalent to the 'K3' engines". The bold type has
been added to the "standard parts" to show that Gresley's LNER was at least
as standardized as Swindon and that the B1 could be produced from existing
parts designed for other classes. The B1 class was far "more standard" than
the LMS class 5, many of which members did not share common parts. Hughes
also deals with designs which were not built, or were constructed in lesser
numbers due to the purchase of the Austerity 2-8-0 and 0-6-0ST designs, and
how the K1 design (attributed to Thompson, rather than Peppercorn) displaced
the upgraded J11 class.
01: 1944: Thompson
Thompson appears to have had a great admiration for GCR locomotives
and in 1944 he commenced to rebuild some of the Robinson 04 class with B1
boilers and cylinders.

4-6-2
A2: 1943- Thompson/Peppercorn :
The A2 class was in reality a number of small classes sharing one
common feature, namely 6 ft 2 in diameter drivin wheels. They were
mixed traffic locomotives.
A2/2:1943 Thompson:
This class was the product of rebuilding the
Gresley P2 2-8-2s as Pacifics. This conversion
was necessitated by heating trouble in the coupled axle boxes on the P2 mikados
(see N. McKillop in the relevant section).
The rebuilt locomotives incorporated three sets of Walschaerts valve gear
in place of the former 2:1 arrangement and the outside cylinders were positioned
behind the leading bogie.

The last four of an order for V2 class

boilers and cylinders (which were similar to those fitted to the 2-6-2 type)
these engines resembled the A2/2 class.

A2 :1947 : Peppercorn :
Peppercorn modified the A2/3 design by moving the outside cylinders
forward to a position in line with the centre of the bogie. At first, most
locomotives were fitted with single chimneys, which anticipated British Railways
policy. Later, some A2 Pacifics were modified with double chimneys for use
on long distance, high speed services.

The riding of the [Peppercorn] A1 and A2 locomotives did not strike
me as in anyway dangerous, but I cannot say the same for those Thompson
monstrosities, the A2/1, A2/2 and A2/3. These engines, with their longer
wheelbase, developed quite an alarming "yawing" motion which at times could
be quite disconcerting..

The yawing maotion was due to the flexing of the frames ahead of the
outside cylinders and he also criticised the use of the B1 bogie which was
inadequate for the much larger Pacifics. He compared this to Ford cars fitted
with transverse front suspension.

"the whole locomotive as rebuilt looked a thorough misfit. Everything
about it looked wrong particularly the inordinate length between the bogie
and the leading pair of coupled wheels. He called the P2 reconstruction as
mutilation. On page 114 he stated that the A2/1 slipped at the slightest
provocation and "On arrival at Aberdeen we found that some of the bolts securing
the pipe to the main frame had worked loose, and the nuts were
missing".

Al/1 :1945 Thompson
The first Gresley Pacific ("Great Northern") was rebuilt to act as
the prototype for a proposed new passenger class. The design features
incorporated may be regarded as an extension of the policy first promulgated
in the A2/2 class. Cylinder layout and boiler pattern were similar in both
designs. New features, incorporated to facilitate maintenance, included a
hopper ashpan and rocking grate.

With the exception of the newly designed bogie and cylinder arrangement,
this mixed-traffic design was based on standard parts. The boiler was a slightly
modified version of that fitted to the Gresley B17 class and the cylinders
came from the K2 class. The bogie came from the B17 class and the drivinng
wheels from the V2. When tested it proved to be as efficient and as powerful
as the LMS class 5.

Whilst a fireman at Doncaster in the Banbury link, which worked freight
onto the Great Central to Leicester he was asked to travel up to King's Cross
on the cushions with Driver Harry Jesson to fire a return working from King's
Cross to Mexborough. He had expected a typical ECML "big engine", but it
was B1 No. 61166. He was warned not to let the locomotive produce dark smoke
or blow off in the terminus, but he had an excellent fire ready to tackle
the climb out of London. The locomotive was fitted with a speedometer and
beyond Biggleswade they were doing 90 mile/h and the vibration was great.
He had no difficulty in picking up water in spite of not knowing the route.
They arrived back at Doncaster somewhat early.

Most of the B12 class were rebuilt with larger boilers by Gresley (see B12/3),
but a number of the original locomotives were retained for work on the Scottish
G.N.o.S. Section, due to their limited axle-loading. When new boilers were
required, Thompson introduced the No. 25A round-top type (see also J20 below)
to replace the worn-out Belpaire boilers.

B16/3: 1944: Thompson:
In 1937 Gresley replaced the three sets of Stephenson with his derived
motion on some locomotives of the Raven B16/1 (S3) class. 1944 Thompson rebuilt
some of the original type with three sets of Walschaerts gear. Some references
to this latter rebuilding infer that Thompson altered the
Gresley modified engines: this is incorrect
(see RCTS which makes it clear that
the further modification had been planned but was not
implemented).

Similar to the NER X class (LNER T1) 4-8-0T, both in overall design,
and in operation. From 1943 an improved boiler was fitted and this sub-class
was known as A7/1. This work continued after the formation of British Railways.
One locomotive spent some time at Northwich prior to WW2. Latterly many of
the class worked from Hull Springhead mpd. \ther author workerd with the
class which tended to have leaking tanks which caused slipping which aggravated
the problem...

Claimed (p. 139) that L1s steamed better than LMS 2-6-4Ts (at Neasden),
but that did not ride as well, partly due to the lack of axlebox wedges which
had been eliminated by Thompson as they savoured of Gresley
practice..
