Following the success of the Ready to Run, Ixion produced
Hudswell Clarke a few years ago, Chris Klein of Ixion has
cooperated with Chris Basten of Dragon Models to produce a
model of the Peckett E Class 0-4-0ST under the Minerva
brand. Peckett & Sons, (from 1914 Peckett & Sons Ltd, the
builders plates changed) built about fifty between 1903 and
1940. The main customer seems to have been Ebbw Vale,
presumably the steel works, though the most well known
would be Swansea Harbour Trust. The SHT locos were
eventually taken over by the GWR and lasted into early BR
days. Even this history is more complicated as some E class
used on Swansea Docks were owned by Powlesland and
Mason who seem to have been some sort of contractor.
Models are only supplied directly from Minerva (standard
DC) or from EDM Models who are supplying with added DCC
or DCC and sound. I pre-ordered a standard plain black version
from Minerva. There is a choice of the black, a dark Brunswick
Green (GWR) and a light green lined in black and white, similar
to one of the options for the Hudswell Clarke. What you
actually get in a very substantial double box is, I think, one of
the late surviving GWR examples in whatever colour, with a
choice of three dome/safety valves and a comprehensive set
of brass etched GWR plates for the early numbering, later
renumbering and BR days plus smoke box number plates. This
etch also contains two flat brass rectangles to make the cab
side sliding shutters and a full set of GWR style lamp irons
which you have to position and fit (and paint) yourself. These
irons are of course the GWR side fitting style, there are no
conventional irons for slot on the back lamps though as far as
I can see Peckett fitted one on the saddle tank front just below
the top and another above the waist band on the cab rear on
their industrial versions.
The choice of domes is a late type with pop safety valves, a
version with Salter safety valves, with which Peckett persisted
after most other makers had changed and a fancy dome used
on several of the small industrial locos that the GWR took
over.
There was an article and drawing by Ian Beattie published in
Railway Modeller for October 1989, which I suspect has more
than a little influence on this model. There is a photograph of
1143 taken in 1953 in this article and another of the same loco,
but the other side, at the same time in Russell’s GW Absorbed
Locomotives, now that must be a first. Note that at this date
1143 carried much bigger Swindon style injectors. Peckett &
Sons Ltd, An Album of Official Photographs compiled by
Andrew Smith and published by the Industrial Railway Society
also has pictures, but they are what the title says and are
almost all in photographic grey and not necessarily how the
loco reached its buyer. Note that the number which Peckett
painted on the tank for the works photograph might not
belong to that locomotive. A search on the internet will turn up
more pictures. Photographs of 1143 and Beattie’s drawing
show a plain topped dome still with Salter valves, many of the
works photos show a highly polished (brass?) dome with a lip,
rather like the top of a chimney. Now whether some poor
apprentice was sent off to polish a suitable one for the works
photo and the buyer got something else, who knows, but there
are several pictures on the internet of other Pecketts in
preservation with this lipped dome. Beattie's drawing shows
the chimney just taller than the plain dome, whereas from
photos, I think the chimney on the industrials looks to be a
fraction taller again.
Frank's modified and lined version
I bought a plain black version, although the buffer beam is
red, as are the injectors, associated piping and the sander
operating levers. I've noted that some preserved locos have
these in red, maybe it was Peckett practice but I thought
looked a touch 'Thomasesque'. I'd already decided that I
wanted mine in lined red. Another Peckett practice was to
polish the raised band half way up the cab back and under the
cab side cut outs. The strip is on the model but painted base
colour. You cannot tell from monochrome photos, but this
band looks like polished steel. Keeping it clean must have been
a footplate crew's nightmare and I suspect it didn't survive the
first repaint. This though posed an aesthetic problem. It just
wouldn't look right to have steel band round the cab and a
brass dome. The decision was to some extent made by
breaking one of the plastic knobs holding the curved handrail
on the tank front, I'd specify brass dome and hand rails in my
order to Peckett and have the steel band over-painted.
Minerva say they are testing every one, and mine ran almost
smoothly out of the box. I say almost, watching the loco move
even at very low speed the linear motion was fine, there just
looked to be a slight dither if you watched the wheels turning.
There are fairly basic instructions of how to get the bottom
plate off for lubrication and how to remove the body to add
DCC. Fortunately the body is held together with non stick glue.
I can best describe the adhesive used to fix cab floor inside the
cab shell, the cab front to tank and tank supports into the
footplate as having been of the impact variety, well past its
sell by date. With care I dismantled the body, but left the
injectors and piping on the tank and sander rodding on the
footplate. The same adhesive had been used to fix the brake
hangers which I eased out of the chassis. One side of the brake
rodding runs to the rear and connects to the cross shaft at the
rear. The cross shaft moulding can be pulled out of the chassis
casting. The brake rigging is most peculiar. On mine, the brake
rodding only ran to the cross shaft at the back on one side, on
the other it finishes at the rear brake hanger. I don't think it was
broken as there was no sign that there had ever been glue on
the left hand end of the cross shaft, which incidentally floats
unsupported. I've since seen another model which is identical,
but surely it couldn't have worked like this. Beattie shows the
rear section of rod in his side elevation, which is the right side
of the loco, but the photograph in Railway Modeller of the left
side doesn't have it. However neither does the right hand side
in Russell's book. My suspicions would fall on the GWR,
perhaps they changed the rigging to a centre pull with a yoke
to the rear; did it perhaps have a steam brake added?
The buffers are held with spring circlips, if you want them off,
keep a firm grip or the carpet monster will devour them. Under
the very shiny black paint the buffers are I think brass. I rubbed
down the faces to give a key and painted then Humbrol
gunmetal. If in use they wear through the centre of the paint to
black they'll look even better. The cab interior is black, so
whilst I had it apart I painted it a cream/buff shade. Since there
is interior detail, might as well be seen.
Once the brake rodding and hangers are removed the
wheels can come off. There are springs under the bearings on
the front set.
I removed the motor, unsoldered the pick-ups and speaker
wires and found the gears very loose on the shafts. There is a
lot of side drift and the gears are able to wobble slightly. The
idler gear wasn't fully meshing with the gear on the driven
axle. I wondered if this accounted for the apparent dither on
the wheels. I tapped out the shafts to both worm and idler
gears and put them back with washers either side to align the
worm gear dead centre under the worm and the idler so that it
meshed with the spur gear on the worm gear and with the
gear on the driven axle.
Note that you have to
gain access from the
bottom, and though not
obvious, the slot narrows
towards the top. Stick
the washers to the gears
with a minute spot of
superglue. All was then
dither free on
reassembly. Whilst I had
the gears out, I
remodelled the rear
sanding pipes. The bent
version provided is right
for the late GWR/BR era
on 1143, Pecketts more
often had a sweeping
curved pipe supported
off the chassis side. The support is a handrail knob, one of
those long ones of no set length. The pipe itself doesn't go into
the footplate any longer but is held by another knob right at
the top of the chassis where hopefully it won't be seen.
Also whilst I had just the chassis casting I removed what I
think it is a crude representation of the tank balance pipe
under the boiler. That was eventually replaced by copper wire,
probably 6 amp cable. It stands further out and passes
through the sanding levers. This has to be put in as two quarter
circles, one each side. I drilled holes for them in the underside
of the tank and fixed them with some very old Bostik, as they'll
have to pull out to remove the body.
As far as I can tell, having fought off the kids at Middleton
Railway's Santa Special to look at the Peckett in the museum,
the sanders are operated by pushing a lever in the cab on the
right hand side which moves forward, presumably to operate
the front sanders and back to operate the rear ones. Motion is
transferred from the right hand side to the left by a cross bar
operated by the upright piece under the tank. As supplied
there isn't a rod going back to the cab, Beattie missed it and it
is difficult to see behind the injector piping on photographs. I
added that, it goes inside the tank support bracket at the rear.
I haven't yet found a photograph of an E class taken from
slightly above, but Peckett's normal practice seems to have
been for the sander operating rods to terminate in a crank on
top of the sand box, not one that disappears down the back. I
haven't done anything about that until I find out for sure. Note
that the operating lever for the Peckett injectors goes outside
the rear tank support bracket. On the GWR version with the
bigger GWR injectors it is inside the bracket. I've repainted the
pipework brass and copper but left the sander operating rods
red.
What Beattie missed in his drawing, and the model hasn't
got them either, are the springs. The tops of the springs should
show clearly above the footplate. A bit of bodging with
Evergreen strip and tubing for the hanger tops made
something presentable. Having gone to the trouble of making
them I painted them gunmetal so they can be seen.
The wheels aren't black but a shiny plastic dark grey. I
painted them black and lined them. I should have protected
the gear and axles and grit blasted them as a key. Time will tell
if the paint holds. I've said that I think one of the brake pull rods
is too short for an industrial version, I remade both from brass
strip. Getting the original off the hangers broke the locating
pips so I drilled and fitted the new ones with cut down Peco
track pins superglued in place. I also mentioned that the brake
shaft 'floats' at the left hand side, it doesn't now, a long split
pin into a hole in the chassis casting cured that.
I don't like the springs which are on the rear of the coupling
hooks. They are so weak that the coupling pulls a long way out
even with a fairly light load. I've replaced them with
compression springs up
to the rear of the buffer
beams.
The cab floor and
firebox somehow don't
look quite right. There is
what I think is the sander
lever, but no reversing
lever though there's a
square hole in the floor
to take one. I've put one
in, probably totally
wrong, especially as it is
an American casting.
There are no sight
glasses, just some little
mouldings where the top
and bottom of the
glasses should be. I
removed them and added some sight glasses which are
probably ABS or Wrightlines. I've also added a bit of brass wire
coming up vertically from the fittings on the firebox top,
otherwise how would steam get to the whistle? Similarly I've
added a bit of copper wire coming down from the pressure
gauge.
Unfortunately I lost one of the little mouldings from the sight
glass positions. I hadn't thought of a use for them until I read
the list of sound effects that EDM's chip contains. Drain cocks,
interesting, as there aren't any on the model, these mouldings
might have done. I made some in brass.
As I reassembled the model I found a couple of tight spots.
The slide bars and crossheads are coated with some sort of
lacquer. It is worth filing up the lands on both bars and
crosshead and polishing with fine emery, a fine nail board is
ideal. The piston rod is a very tight fit in the cylinder and I
opened the hole out and polished the piston rod. Holding the
cylinders slidebars up, the crosshead drops in under gravity, it
didn't before. That possibly solved another potential problem.
Paul Martin at EDM says some locos have a 'tick' which he has
traced to the cutting off of the crosshead/piston rod casting
which, on some models, has left a burr on the piston rod end.
A conundrum. The buffers are brass, as is the top of the
chimney and I think the tank filler, all painted black. The dome
could/should be brass but it is black plastic. I've picked the
Salter valve version and added the lip from Evergreen tubing.
I'd looked for what military modellers use for brass, they
usually are better painters than railway modellers. Most that
looked remotely presentable are multilayer systems so I was
amazed to see a can of Valspar Brilliant Metallic Brass in B&Q.
I speculated about £8, and tried it out on the fancy GWR dome,
thinking to keep the pop valve version as last resort. It doesn't
come up like the cap on the spray can but as tarnished/end of
shift I think it is acceptable. Since I sprayed it the dome has I
think tarnished to a slightly more coppery shade, I wonder now
how it would look over coated with gloss varnish. However by
then I'd already sprayed and fitted the Salter valve version and
added something inside to represent the business bits. Only
then did I find that EDM are having proper brass domes cast.
I've raised the chimney a fraction, added lamp irons front
and back and fitted a handrail across the cab back. Some
Pecketts certainly had it and without it I don't see how my
crew could balance on a buffer and hang the lamp without
infringing about a dozen Health and Safety Regulations. I've
put a straight hand rail over the smoke box, not all had curved
ones. One thing nearly all Pecketts seem to have is a Roscoe
lubricator on the rear of the chimney. Laurie Griffin 19-35 is
suitable, 19-34 is too tall.
If there is such a thing as a standard Peckett livery then the
main body colour is edged (banded) in a darker shade or
maybe black. It is lined between the two, in the early days with
incised corners. Rather like persisting with Salter valves
Peckett seem to have persisted with incised corners. On the
tank, cab side and cylinders there's a double line also with
incised corners. I've lined mine as if both body colour and
banding were black. It is done with Fox transfers, 0.35 mm red
for the edge lining. The panel lining is 1mm red lightly
varnished then with 0.35m black added down the centre later.
Brilliant it isn't but better than I can do with a ruling or lining
pen. I've spray varnished to finally seal the lining with
Railmatch satin but it has come out a bit matter than I
expected or wanted. If you buy a lined green version, edge the
panels with black and line between in white you will be quite
close to Peckett's style.
Add a crew and it only remains to pick a works plate. Those
supplied are beautifully etched with fully readable, raised
letters. Unfortunately, Peckett's plates were flat with the
lettering cut in, a totally different style.
Therefore, what you get, whatever the livery, is the GWR
version a` la Beattie, albeit with Peckett injectors, and that if
you want an industrial, and I suspect many will, to get it into
that condition will require a bit of effort. If my research, two
books, one RM article and the internet can pick up these
apparent anomalies, it seems to me that a little more care
might have been taken before committing to production. That
would have eliminated the questionable brake and sanding
rodding, and a careful look at almost any book on Pecketts or
even the internet should have caught the plate problem.
The loco runs just as smoothly as before but without that slight dither. What is noticeable is that it now starts on just one volt, not nearly two, and draws 60mA instead of just over 100. I suspect that easing the crosshead slide bars accounts for most of that. It may seem I've done a lot of work to 'improve' this loco, but mostly it has been a case of making it into what I wanted. Would I buy another? If someone can come up with a photo and livery details for Powlesland & Mason or Swansea Harbour Trust, yes, like a shot!
