Additional Notes
LNER Numbering - there were huge variations in how LNER numbering was applied. Sizes varied, location carried, style varied,
sometimes just ‘NE’, sometimes still with the GCR cab side plate and the letter ‘c’ added to the LNER number, sometimes on the
tender but mainly on the cab once the LNER got themselves sorted out.
Photographs should be consulted when deciding what number to have. Of course in GCR days it was all rather simpler.
Locomotives could have a carriage heater connection at the front as they became used on passenger trips which would mean
that a heating pipe should also be added to the tender.
Smoke box handles - for this class the wheel arrangement was kept throughout their lifetime.
There are more versions of the chimneys and domes than catered for by the kit. The original chimney was of a much finer
appearance and rapidly failed in service.
Ramsbottom 2 column valves were originally fitted and a branching arrangement used for the traditional 4-column appearance.
These were originally uncased but casing was added later. Ross valves replaced the Ramsbottom valves during superheating.
Tail rods on the cylinders were removed before grouping but I have no dates for this, it seemed to happen over a longer period
than other GCR classes, but before grouping. On super-heating a
‘snifting’ valve was fitted behind the chimney. At the same
time the ash ejector was fitted on the right of the Smoke Box.
Centre steps were removed before the grouping, at speed they could ‘whip’ and potentially hit the connecting rod.
Livery was perplexing. Originally in full GCR green regalia, they soon reverted to lined black and then the LNER painted them
green again until WW 2, when they all became black again. Under LNER management, the beading was always unpainted and
usually unpolished.
Tenders when built for 192, 194 were the GCR 3,250 gallon version but these were soon replaced by the group standard with
plated sides.
As with all models from this era, the best thing a modeller can do is refer to published literature such as
Ÿ “Locomotives of the LNER Part 3A” from RCTS
Ÿ
“Locomotives of the Great Central Railway” by E. M. Johnson
Ÿ Photographs from various collections - usually available at shows such as Scaleforum and Scalefour North
Ÿ “Yeadon’s Register of LNER Locomotives - Part 13”
These locomotives, known as the “Jersey Lilies” ranged far and wide and could be seen as far away from GCR rails as Plymouth
and Weston-Super-Mare, even running a slip coach at one stage. They ended their days doing light duties on the BR Eastern
Region. Their visits to Plymouth are a good excuse to put a “Green, with rivets”, next to a GCR Class 8B, “Green, without rivets”
Important Note
This kit has been designed for P4 or EM standards. Alternative parts have been designed into the brass and nickel silver frets.
There are plenty of spare parts for the smaller items. Considerable additional work will be needed to build this kit to ‘00’
standards. Remember that ‘00’ and EM wheels will cut into the boiler space. For EM modellers care must be taken not to
increase the upward movement of the wheels if sprung or compensated by filing out the axle slots in the frames. If the kit, when
built, has a lot of side play then even the P4 version will find the wheels hitting the boiler. In all cases the boiler can be ground
out to clear this.
Notes on the kits and constituent parts
The etched parts in this kit have been designed using a CAD program (TurboCAD 18.2) to ensure accuracy when fitting the parts
together. Included in these notes are:-
Ÿ A list of etched and cast parts
Ÿ
A list of additional and optional parts
Ÿ Drawings of the etch fret
