Roundhouse Engineering Cilgwyn Quarry Railway 0-4-0ST LILLA
Another off my "I'd like to do one of those" list has recently been completed: A Roundhouse
Lilla in the condition that it ran when new at Cilgwyn Quarry in the Nantlle Valley here in
Photos of Lilla in its pre-Penrhyn Quarry days (i.e. before 1928) are hard to come by and I
only know of two: A Hunslet works photo of the loco brand-new, and a single image of the loco
at work at Cilgwyn. Interpretation of the photos is very subjective but until more photos
appear in the public domain nobody can be absolutely certain how the loco looked at that time.
However, the photos do show the hardware changes that have occurred during the loco's
existence, mainly after it moved to Penrhyn, and they are distinctive enough to reproduce in
The most noticeable difference concerns getting water from the saddle tank in to the boiler.
At this time Lilla only had one injector fitted, which was on the left side of the loco. A
water pump driven from the crosshead was provided on the right side. The pump has been
reproduced, together with the associated pipework. On the full-size loco the holes in the cab
front and footplating were re-used when the pump was removed and a second injector fitted,
hence why the two sides do not match.
Other changes included:
- Sheathed wood dumb buffers.
- Lamp support arm on front and rear lamp brackets.
- Whistle on the cab roof instead of on the cab front.
- Additional handrail knob on chimney front.
- Sandboxes alongside the smokebox and associated operating linkage.
The full-size loco retains the stub of the saddle tank support for the sanders reach rod to
The brand-new model also received the following modifications:
- Removal of preservation-era tool box and vacuum brake piping.
- Fitting of left-hand injector water valve handle.
- Fitting of additional blower and lubrication pipework.
- Removal of derailment bars and mountings.
- Fitting of reverser and drain cocks reach rods.
Finally, it was painted and lined in the known Cilgwyn colour scheme.
Argyle Locomotive Works Bantam 0-4-0ST
If there is a word that can be used to describe an Argyle Loco Works "Bantam" it might well be
"cute". This one came here showing no signs of a lot of use, but definite signs of trauma.
The most noticeable fault was the bent frames. The loco's 0-4-0 wheelbase is only 55mm but it
has an overall length of 285mm, meaning that it has a huge amount of overhang especially at
the back end. Something had occurred that caused the rear of the frames to droop downwards so
the loco was completely dismantled and the frames were straightened.
Another issue was that the entire gas system was missing. A new tank. control valve, burner
jet and pipework were kindly supplied by Argyle.
Attention then turned to the paintwork. The original plan had been to retain the existing
paint but my usual plan of a run through the dishwasher led to most of it coming off! The
small remainder was stripped off and the loco was completely repainted. This included the
frames, the insides of which are clearly visible, and so while the outside received a coat
of black the inside received a coat of red.
Yellow lining with black edging was then applied, followed by reassembly and a steam test.
Archangel Darjeeling 'C' Class Pacific 4-6-2 No. 808
This model of a Darjeeling C-Class Pacific was built by Stewart Browne of Archangel fame.
The model came here with only the frames, wheels and a few other details painted. My task was
to apply suitable, and authentic, paintwork. Information kindly provided by David Charlesworth
of the Darjeeling Himalayan Railway Society (to whom I am very grateful) soon revealed that
our choices were: DHR green with red and black lining (carried from 1914 to 1948), Indian
Railways plain black (1948 to early 1970s), and black with blue cab and tender combined with
red and white details (early 1970s to withdrawal). It is dubious variations of this latter
livery that preserved
807 and 808 carry today. I'd never seen a black one in this scale so
I suggested it to the owner, and he agreed. Like other models of a similar size, they can gain
a real and purposeful workaday appearance in plain black with a few contrasting details.
There are very few pictures of these locos around, and my major source for detailing was,
again, the large-format book entitled The Darjeeling Himalayan Railway - A Photographic
Profile 1962-1998. It is referred to as "The Australian Book" and it includes a full-page
colour photo of 807 in black in 1962.
After dismantling, a good clean, bodywork preparation, and lots and lots of masking etch
primer and two coats of satin black were applied. It was then a case of reassembly and dealing
with a myriad of the smallest of details. Finally, with the paintwork finished, the final task
was to affix number and works plates from MDC to the cab, tender back and smokebox and NF
lettering to the tender sides.
Roundhouse Engineering Mr. Merlin's Pooter 0-4-0T PANGUR BÁN
PANGUR BÁN is another of those rarest of Roundhouse Engineering locos: a Mr Merlin’s Pooter.
The owner had managed to obtain a bare Pooter chassis, the vibrating levers and slide blocks
for the Hackworth valve gear and, most importantly, a brand-new body and cab roof from a Mr
Merlin’s Pooter or Roundhouse Erica (they are identical). With these few components to hand
the challenge then was to turn them in to a fully working loco and the hunt began for the parts
needed to do so…
A trawl through our respective Bits Boxes produced more useful parts: Safety valve, dome
(modified from a Roundhouse Tom Rolt), regulator, smokebox dart, meths tank (from a Lady Anne),
meths burner, dummy tank fillers, chimney cap and whistle from the owner's, and dome retaining
clip, boiler retaining band, chimney base, cylinder covers and a few other smaller components
from mine. Old-style rectangular valve chest cylinders were needed and so a pair of those were
removed from my own Lady Anne (and replaced with lovely new current-style ones!) and
Roundhouse provided a host of new parts, including wheels, axles, bearings, cranks, coupling
and connecting rods (same as Katie / Billy / George, etc.), centre-pivot reversing lever (from
an Alco), bottom-drain lubricator and superheater tee.
That left the difficult bits to find. I took on the task of supplying the missing valve gear
parts. I made the return cranks and valve rods, but making the slide balls was not
something I could do so my good friend Adrian was asked if he would do so, and he did! They
are a difficult thing to produce and wear on the slide balls is often the cause of Pooters
becoming unused Shelf Queens. Once the chassis was running we knew we could finish the loco.
The owner took on the task of finding a Pooter boiler, which took a while but eventually he
was successful. Once I had the boiler to hand, I made the inner firebox that supports it and
allows it to be fixed to the frames.
It was then a case of doing the plumbing, making a new chimney, fitting some of the decorative
body components and painting in bronze green with orange lining.
Could this be the last new Pooter…?
Roundhouse Engineering coal-fired Dylan 0-4-0STT ODIE
It was back in 1987 that I first encountered 16mm/foot live steam garden railways. This was
at the renowned Paddock Railway at Hampton Loade station on the Severn Valley Railway.
I was an SVR volunteer at Bridgnorth back then and it became a nice Sunday afternoon diversion
to travel down to Hampton Loade and run my O-Gauge stock after the 16millers had finished
their session. I'd not seen anything in this scale before, and I was hooked immediately. My
good friend Paul would let me run his meths-fired Roundhouse Dylan, called
ODIE and named
after the dog in the Garfield cartoon strip. The loco's nickname was Bill, for reasons I am
sure I do not need to explain.
Hankering after my own loco, my desire was sated when I purchased my own Dylan from good
All three of us drifted away from Hampton Loade over time, and my contact with ODIE ended.
Paul converted it from a pot boiler to internally-fired meths, and then rebuilt it with a
Shawe Steam Services coal-fired boiler and repainted it blue. Some years ago Paul drifted
away from 16mm and sold a lot of his rolling stock to Tim, including ODIE.
It was an absolute delight to be asked recently by still good friend Tim to repaint ODIE in
to his standard bronze green with orange lining livery. Tim stripped the blue paint so all I
had to do was apply the new colours. Opening the box was like meeting an old friend again
... after a 25 year gap I reckon.
The pictures show ODIE in its new paint, outside the loco shed at Hampton Loade in 1989 (in
green on the right, with my red Dylan on the left ... no shelter in those days, we just got
wet) and at the late Eric Skinner's line in Solihull with Paul's carriages around the same
Roundhouse Engineering 0-4-0 HARLECH CASTLE / CASTELL HARLECH
The owner of this Roundhouse Engineering Harlech Castle / Castell Harlech used to drive the
full-size loco at the Festiniog Railway so he knows it well. Following the recent visible
modifications (full-width bonnet and vacuum brakes) and repaint he asked me to make his model
look "like INA used to look". INA is the loco's nickname and is derived from the initials of
its originally intended owner, Mozambique's Instituto Nacional do Acucar (National Sugar
Institute), the initials of which were on the cab sides when it first arrived in Wales.
Work on the model included:
- Addition of fuel filler and exhaust strengthening strut/angle.
- Fabrication and fitting of cab door handles.
- Application of FR PW, NET (Nottingham Express Transit) and other transfers and
* Black : Rod ends, cab front/rear around bonnets, exhaust, wheels,
handrails, window rubbers,
couplings, radiator grille,
base of body.
* Yellow : Front and rear of footsteps, crank pins.
* Cream : Cab interior and desk.
* Grey : Air filter and horn.
- Black lining around panels gaps and lock holes, on fuel gauge and axle cranks.
- Application of all-over matt finish clear coat.
- Weathering of frames, body and cab roof.
ELR Engineering Quarry Hunslet 0-4-0ST HUGH NAPIER
Another ELR Engineering Quarry Hunslet has been on my bench for attention. Others that have
been here have run very well, despite their many shortcomings in other areas, but this one was
reported by the owner to be off-beat. After checking that the slip-eccentrics were not the
cause of the problem my diagnosis was that a valve head was in need of repositioning on its
spindle. Unfortunately with these particular models there is no easy way to achieve this
without completely dismantling the locomotive. Removing the bodywork, boiler and footplating
allowed access to the valve chests and after half a turn of one valve buckle perfect running
was restored. The time then came to reassemble it...
You can read in the Gallery section about the issues that I have found with other locos of the
same type, and this one exhibited much the same, along with a saddle tank which was coming
apart at the seams. With the owner's consent it then went through the normal programme of
bodywork modifications and adjustments followed by stripping of all paint, repainting and
lining in the earlier Penrhyn Quarries scheme.
ELR Engineering/Roundhouse Engineering Jack 0-4-0ST ST CHRISTOPHER
ELR Engineering converted this standard Roundhouse "Jack" 0-4-0ST to coal-firing. It came
here for a check-over, service and repaint. As is usual with these things, the job list grew
a little and ended up looking something like this:
- Restoration of axle water pump to working order.
- Modification of the saddle tank filler cap to give a positive fixing, rather
than depending on gravity.
- Fitting of Swift16 buffer beam overlays.
- Modification of the cab roof to prevent scratching of paint on cab front.
- Unblocking of boiler water gauge glass bottom pipe.
- Descale of the boiler.
- Recalibration of safety valve for 60psi operation.
- Various modifications to ease future disassembly and maintenance.
- Fixing of a water leak from the saddle tank.
- Stripping of paint from body, roof, smokebox, etc.
- Application of etch primer, satin black, Victorian Maroon and red/black lining.
All of this was followed by a thorough testing session to make sure all was well.
Cheddar Models Samson 0-4-0T No. 31 APHRODITE
This Cheddar Models Samson, like the same owner's Hercules, has been lowered by about 12mm
by reducing the height of the cab and chimney. The body, boiler and smokebox were repainted
Accucraft WD Hunslet 4-6-0T No. 33 ANDROMEDA
This loco was fitted with two-channel radio control and received blue and red lining along
with a significant reduction in the amount of bare metal usually exhibited by this model.
