Getting a bit plastered!

Having done some more testing on the track, I was happy to start the plaster work over the aluminium flywire to form the hills and landscape. The basic system used here starts with strips of Balsawood (12mm square section cut from sheets) glued just under the edge of the profiled fascia boards. Flywire is then stapled to the Balsawood and the baseboards along the track edges.  Scrunched up newspaper then supports the flywire and also keeps drips of plaster from landing on any hidden track. Plastering is done using Cornice Cement, a much better product than any other plasters due to it having greater adhesive quality and is much harder than the average plaster. Due to its hardness, there is only one layer needed over the flywire instead of two, saving time! When all is dry, the newspaper is removed from underneath.

The profile boards then get their first coat of acrylic paint which will be the final colour for presentation of the layout. The paint is brought up over the edge where it meets the plaster. This does two things; it helps harden the edges further, reducing the chance of chipping and if in future any grass scatter gets accidentally rubbed off the edge, it won’t be obvious.

The back board behind the viaduct has been applied with a photographic backscene of” Llanberis”, a welsh mountain scene printed on a premium paper which has a waterproof plastic backing. Applied using spray contact adhesive, it went on beautifully and am pleased with the result. The plaster work will then meet the bottom edge of the photograph.

"Commercial Street" - 1960s South Australian Railways

Here is a unique hinged baseboard idea that many English modellers had developed many decades ago of modelling a fold up railway known as the Minories. This idea consisted of a terminus station at one end and a specially set out track design at the other end. At the Terminus Station, which usually had high surrounding walls each side of the whole station, a road bridge straddled the station platforms concealing a pair of hinges. This allowed the two baseboards to be folded over on each other for transport or storage. To make the terminus operable, a fiddle yard would then be attached at the station throat concealed under another road bridge leading into a hidden fiddle yard, which would be bolted on to the Minories. I proposed the idea that if the fiddle yard could be permanently attached to the station throat via another set of hinges, the whole layout would fold up on itself without having separate baseboards, extra sets of legs and no track alignment worries. Having tried the idea, and making use of a large warehouse building as a means of hiding the fiddle yard, and using block sections at the end of each siding, a successful scheme would allow the operator to run trains from the terminus to the fiddle yard and back without touching/handling any engines or rolling stock. Under-track magnets would be located at appropriate positions around the layout to allow hands free shunting using Kadee couplers.


An industrial theme would be appropriate for there were dozens of sidings in and around Port Adelaide and the Port Line in South Australia. Small industrial sidings were everywhere, built in and around roadways, sometimes in the roadways. Roads that ran over the railway with girder bridges or embankments with simple concrete bridges such as those at Mile End or Port Adelaide look visually interesting, and in this case used to hide the hinges on the baseboard. Small passenger stations such as Grange or Semaphore were built immediately next to a roadway and have simpleness to them. Of my own design, “Commercial Street” allows one to run Goods and Passenger trains and have the illusion that the trains have come from and go to a main destination hidden by the warehouse (the fiddle yard). Due to the shortness of the sidings and the use of small radius points, an impressive number of wagons and engines can be accommodated on the layout without being overcrowded.

Even on a small layout like this there is comfortable room for five locomotives, twenty wagons (mostly 4 wheelers), two brake vans and two passenger cars or a pair of railcars.
The layout stands at 1 metre high so when sitting on a standard chair the scene before you is just under eye height. This gives the operator a sense of being in the scene.

The warehouse was made from two Metcalfe Warehouse card kits, kit-bashed to obtain a very close match to the old Woodsons building in Port Adelaide.

Progress with Porthminster

During the course of winter I had to take a break from Porthminster to build a small fold-up South Australian Railways layout for a presentation I had to give at a Convention in September. (See left hand photo at top of this page - a post on that layout will be forthcoming). Once that was out the way, I constructed the platforms at Porthminster and Penwith stations. Construction was somewhat challenging with curved platform faces and very few straight edges.
All track ware then wired to four operating panels, one at Porthminster, the branch terminus, one at the hidden sidings, one at Penwith Junction right behind the Bay roads of the branch, and one at the main goods yard at Penwith Station. The plan is to have three operators (or four if needed) to operate the layout at exhibitions. Some tricky wiring with assisting relays aided the switching of the diamond crossing and single slip at Penwith Junction, and the scissors crossing. I also installed a four speaker digital sound system to pipe steam train sounds around the layout.
Once thoroughly tested, the layout was pulled down and the modules were taken outside the house so the track could be painted. A light rust colour for the rails was first applied (at 45 degrees to the track to cover the sides of the rails) then Rail Sleeper Brown was sprayed over the top (at 90 degrees) to cover the sleepers which were over-sprayed with the Rust.
the track having been spray painted was ready for ballasting. The masking
tape around the platform faces to protect them was removed just prior to ballasting.
Some thoughts into where the point rodding would go were needed. Positioning between tracks needed to be sorted out so rows of foundations could be glued in before ballasting.
Point rodding supports glued in and painted before ballasting.
Ballasting then commenced with the layout set up again. I installed separators (20thou plasticard) between the modules to prevent them sticking together when the ballast glue was applied. The standard mix of PVA glue and water was used after applying a spray of water and detergent.
The plastic separators needed to stop the modules from being stuck together.
With all the ballasting done, the rails were cleaned up and more testing was needed to clear any faults with point motor operations or bits of ballast in frogs and checkrails. A few showed up where the blades had stuck, but were easily remedied with the application of water and some cleaning up.

In October I attended a national convention of the British Railway Modellers Association during which there was a modelling completion. I entered the two station buildings I had scratchbuilt for Penwith Station for the Lineside Structures Trophy. Winning the trophy was a bonus and was the icing on the cake for a good weekend away! The prototype I chose was Radley Station, which fit nicely into the platform arrangement I designed for Penwith. Radley Station also had a nice covered footbridge linking the two platforms and there will be one made to fit the same arrangement in Penwith.

Porthminster Modules & Track

Construction of the modules proved to be more difficult than first thought due to the shapes needed to produce each module. There are so few straight lines in the plan that each module is different from the next physically in shape and depth.  There seemed like mountains of scrap timber left over due to the immense number of jigsaw cuts needed to produce the curved track beds and profile boards.  The first module constructed was the end module with the tin mine.  The two bridge modules were made up without the semi-hidden main line storage loops. Then the two Penwith Station modules were constructed keeping in mind that there was no room for slip ups in their dimensions so that when the last module was constructed that they all meet up without alignment issues.
The layout viewed from the branch junction end. All track work complete.
Operators will be in the central isle while public viewing around the outside.
Once the modules were set up and all clamped together, all the joins were drilled for two alignment dowels and two (3/8”W X 2 ½”) bolts with wing nuts. Each module has its own fold down legs with gas struts attached. These will hold the legs in place during assembly/disassembly allowing a speedy set up and pull down time. The main timber frame of each module comprises mainly Pine of 63 X 19mm cross section. All the baseboard tops and track beds are 6mm MDF. All the profile boards are 3mm MDF. The last part of the plan was to arrange and construct the semi-hidden storage loop timberwork behind the view block of the bridge modules. Some very tricky woodwork was needed here.
Looking along the backdrop with the viaduct to the left
(front of the layout) and the semi-hidden passing
loops for the two main lines.
The reason this layout is being built is due to the acquisition of that beautiful Brunel Viaduct. So it was carefully removed from the cut out layout pieces in which it was built on and arranged on the new modules. On the original layout the last owner had built the viaduct as one piece, but was thankfully only resting, not glued to the piers. The viaduct was trimmed to 3m from the original 4.5m. Some juggling of the deck was needed to allow future cuts to be made at the joins of the modules so that none of the fans would be in the way.   Each pier was trimmed to length so the timber fans and deck would be level. The deck was then aligned to the track plan and clamped. All the piers (cast from plaster with a timber core) were then glued and screwed from underneath to ensure a solid foundation to finally glue the deck to. Once all the glue had dried, cuts were gingerly made at the joins of the modules – a tedious task keeping in mind I didn't want to destroy any of the timber guard railings along the deck. Though the viaduct was laid with code 100 track, ballasted and glued in the 1960s, it was in remarkably good condition so I consciously decided to leave it unmolested and marry it to my code 70 Peco track at either end.

Always seeking a challenge, the tracklaying was begun with difficult areas tackled first. The scissors situated in the middle of Penwith Station yard was made up using four Peco medium radius points and the short crossing. Careful trimming allowed for all the components to be superglued together producing a very unique piece pleasing to the eye.

As I was nearing completion of the track work for the branchline junction in Penwith I had no choice but to hand make the double curve crossing. To get a smooth transition of curves and to get the curved points to fit, the crossing needed the curve of the branchline to start on the diamond rather than after it. I was quite happy with the result and running different types of vehicles through the crossing showed up a few adjustments needed for smooth running.

Tunnel portals for Penwith Station

Tunnel portals for either end of Penwith Station were originally intended to be like the famous Box Tunnel but would have been too large for scenic space I have on the end modules. So a couple of the smaller types were picked from the Great Western stable of portals built for the old Broad Gauge lines. Both slightly different for variety, but very distinctive. They are large and have that low embankment angle on each side of the cutting so typical of Brunel when he sculptured the land for his railways.

Those distinctive curved  walls that flank  an otherwise  typical double track entrance.
The black lines marked in on either side show where the cutting  land profile will be.

I used 6mm MDF as the base to add Slater's plastic stone walling. The capping and upper ridge course are Balsawood, the grey areas are Tamiya filler to join all the corners, angles and edges of the stonework. There are three rows of bricks inside the inner entrance edge, edged with a piece of 1.5mm copper wire to represent the round edge brick that ran the whole way around. Once these are painted and weathered, they will look the part.

This portal measures 450mm across and 135mm high! The other portal has the same height
but is slightly narrower.
 

GWR Diag. C23 Third Class coach

Using the two Compartment sections of the Triang Brake Third coaches can result in a very convincing 10 compartment Diagram C23 coach.
The body was first sprayed with Humbrol 103 Cream, then masked and GWR Chocolate  from an old
 jar of Floquil. Roof grey is Floquil Grimy Black. The clerestory windows were backed with styrene
to fill them as many of the prototype had this treatment. Because the Bachmann wheels are the larger
correct size, a small amount was trimmed from the brake blocks that are cast into bogie. 

 After completing the V5 PBV, the C23 was tackled and basically the following points cover the work.
  • Roof gas piping added to lamp housings along the roof.
  • Upper roof Handrail and end panel steps added
  • Lamp holder brackets at each corner.
  • Bogies trimmed and fitted with Kadees, Bachmann coach wheels replace the plastic Hornby axles.
  • Under floor details fabricated, including Gas reservoirs  queen posts and tension rods, brake cylinder, brake hangers and weight. New bogie bolster centres established for the Hornby 10 foot bogies to correspond to the original drawings.
A three quarter view, ends painted black with other details evident including
those imposingly large lamp brackets. Decals added and the door handles and
waist line in gold using a bow pen. Also the 60 window frames were lined and
painted in using a bow pen. I used the Triang buffers but I may replace those later.
  • 1928 to 1934 Period livery with the gold and black waist lines.
  • Glazing.
  • Interior partitions and seating with sitting passengers added.

GWR Diag. V5 Passenger Brake Van

Not one to pass up a challenge, I saw the potential in making up two different types of passenger stock from a pair of old Triang Clerestory Brake Thirds. Studying the drawings and photos in well known Great Western coaching stock publications revealed the two compartment sections joined together would produce Diagram C23 10 compartment coach. Then trimming one ducket section off the remaining two brake end sections and joining them together would produce a diagram V5 Passenger Brake Van. Upon making the cuts in the right places and joining them together, both vehicles were accurate for length and looked very much like the prototype photos.
The two vehicles cut and joined together V5 front and C23 to the rear,
undercoated. Internal partition roof supports were added to help hold and
secure the new roof to made. 

The V5 PBV roof line was ever so slightly lower than what it should be but I would be happy with that as it's not obvious. The chassis gear would need the four white metal axlebox/springs, two brass etched W iron sets and two Maunsel style axles to ride on. The long tank, vacuum cylinder, brake shoes , hangers, rodding, and side boards were scratch-built from styrene and spring steel wire. The side boards were secured using staple gun staples which are quite effective given they have a rectangle cross section. Kadee couplers were secured in place with screws and some weight added under the floor.
V5 PBV with cream air brushed on ready for masking for the chocolate brown.
 The vehicle would have the 1928 to 1934 livery so masking for the chocolate had to be carefully done to be faithful to the scheme. Once the brown was dry it was masked up for grimy black to the side sills and chassis including the buffers and beams. 
Roof supports added. roof made up, transfers added, windows
picked out in "Mahogany"

A roof was made from 30thou styrene, bent and formed in the right places. I glued in a couple of lengths of code 100 rail upside down along the curve line inside the roof. This would aid in holding the roof to shape and not warp over time. The roof was glued on and painted, along with the last single gold line separating the cream from the chocolate. This was done with a bow pen.

Roof added with rain strips, lamp housings, end handrails and some weathering to finish.
The final result is convincing and I look forward to towing the V5 behind the 517 class sometime soon.

GWR 14XX to 517 Class conversion


I am trying to keep reasonably authentic motive power and rolling stock around the St. Ives, St. Erth, Truro to Penzance area in the late 1920s and early 1930s. Upon researching this era, I discovered there were two 517 class engines brought in as temporary replacements for the 44XX and 45XX engines when they were recalled for overhaul in this time period. That was all I needed for an excuse to have one of these interesting little engines. A Chinese made Hornby 14XX was acquired and the following is a summary of the changes I needed to accomplish a close enough model that would look right at home on the branch and catch the eye of a Great Western enthusiast.

The 14XX out of the box.
The 14XX as it was out of the box was a reasonable runner but it had that annoying limp that so many modellers complain about. Something was going to have to be done about that later! After removing the body the cab roof was able to be prised off as it was a separate piece and the smokebox/boiler assembly could also be detached. On examining the drawings for both 14XX and the two versions of 517class, the easiest option was to convert to the Swindon rebuilt engines which keep the trailing wheel with the outside axle boxes, and most of which had the large style bunker. Also I found that a number of the 517 class had numbers in the low 1400s in my era, and as it happens 1427, which is the number of this particular Hornby model, was a Swindon shed engine. It may have well been one that was temporarily sent to Cornwall!

Using drawings and photos from an article and some internet research, a list of initial expected modifications was made.
  • ·         Remove the sandboxes over the front driving axle
  • ·         Cut off the cab level with tops of the side tanks
  • ·         Cut out 4mm of tank length (see photo, if you cut front of the number plate you can preserve it)
  • ·         Cut out 1.5mm of smokebox length in front of the funnel (the funnel should be in the centre of the smokebox after re-joining but the handrail disguises this somewhat)
  • ·         Cut out about 2mm of footplate in front of the smokebox, there is a join in the plate so cut forward of that so you can use that as a legitimate joint in the plate work
  • ·         Remove the funnel and whistles and keep
  • ·         Remove the top feed cover behind the funnel and its associated piping
Smokebox front and door cut off, top feed removed and piping.
To preserve the number plate the tanks were sliced right on the
row of rivets next to the number plate, then 4mm taken out .
At this stage the body parts were then superglued together and the following parts made up.
  • ·         Extend footplate thickness by 1mm using 40thou square strip
  • ·         Make a new cab using 20thou plasticard, trim the original roof and install the handrails along either side of the top of the roof, and install the whistles as per your photos, some were in front and others on top, also I drilled out the sliding hatch and glued on a sliding plate
  • ·         Make up 4 steps and a pair of boxes on the side tanks
  • ·         Add sanding boxes on the front and also a curved cover plate over the front cylinders under the smokebox. I used some 5thou brass shim, and glue the funnel in its socket
  • ·         Face the front splashers with 10thou plasticard and detail with ribbing as per photos
  • ·         Add all lamp irons and 3 fire iron hooks (not 4 like many of the larger tank engines) on the bunker
  • ·         Cut in a concave radius to the front of the bunker at the top, add coping trim to match the existing trim on the side tanks and the bunker
  • ·         Reinstall the handrails around the boiler and slice off all the moulded handrails everywhere else and replace with 15thou spring steel wire or stanchions where appropriate
  • ·         Cut off the original washout/inspection plugs (2 off) either side of the safety valve jacket and put in 4 new ones of the exposed type
  • ·         Add vacuum pipes front to back along the sides of the footplate – note the left side was smaller diameter than the right side in most cases of the prototype
  • ·         There is a pipe that is seen between the rear driver and the trailing wheel on each side of the firebox
The body glued back together, smokebox front re-attached and
cab construction.
I think that covers most of the changes. Obviously the front of the bunker needs be built up suitably incorporating the back cab plate. Also I built a small backhead to the boiler in the cab that reaches down to the top of the motor. On this I added some valves, a sight glass, a couple of pipes and a regulator. I even put two pressure gauges on the front cab plate but these can’t be seen very well once you put in your engine crew, so it’s not really necessary. The smokebox door has the latch handles moulded straight back to the face of the door which looks ugly. So some careful carving with a sharp pointed knife cut away the web behind the handle that is on an angle vastly  improving the appearance. The study of photos for the finer points of detail will show there were quite a few minor differences among the class. So if you pick a particular style, either the Wolverhampton or Swindon rebuilds or if you go back to an earlier era, be aware of the differences.
All the changes and modifications done to the
body, chassis shortened and couplers trial fitted.

PAINTING THE BODY

The buffers and beam faces were masked off, as was the safety valve cover and the two number plates on the side tanks. A grey primer was applied over all, but a little extra was applied to the re-joined areas to ensure they are not seen through the following green coat. It was let dry for a day then the green was sprayed to the required areas. Removal of the masking tape left only areas of black left to pick out with a brush.

The undercoat.
The green added and chassis before re-wheeling.
Required areas picked out in black and the chassis with
new drivers and machined flanges.
Some HMRS transfers for the GREAT WESTERN were applied to the tanks (no need to bother with the buffer beam numbers as they were untouched) and the whole body given a coat of clear to seal up.
It was time to dress up this little tank;

  • ·         Real coal glued over the fake coal in the bunker
  • ·         Springside lamps attached – in this case one in the upper centre position for branch passenger working and a spare lamp attached on the left side footplate
  • ·         Engine driver and fireman
  • ·         Firing irons and a fire bucket hung on the hooks at the rear of the bunker
  • ·         Vacuum pipes fixed to the buffer beams


IMPROVING THE CHASSIS
The chassis was always going to be cause for concern. I was looking at keeping the chassis as it was but many attempts at fixing that limp ended in defeat. So the Hornby driving wheels were removed (one wheel was out of round and another had the wobbles) and replaced with some Romford wheels that I had lying in a project box from the 1980s.  I machine the flanges down to a RP25 profile (as they had the older flange size) and installed using the Hornby connecting rods and crank pins. The limp was still there so I then had to open out of the journals slightly and pack them with a thin sleeve of brass to remove the axle slop. That did the trick; it then ran quite smoothly which left only the trailing wheel to deal with. The large looking flanges stuck out like a sore thumb, so I machined the flanges down to match the drivers. There is a riveted balance weight on the rear driving wheel, so I used some 3Thou styrene with the rivets produced by poking a sharp compass point through from the other side.
Shortening the body meant also shortening the chassis to fit, so each end had some cut off so the chassis sat neatly inside the buffer beams each end.

At the rear end showing the parts cut off the die-cast,  the motor
plate and the plastic rigging leaving the guard irons.
The Hornby chassis has a plastic keeper assembly which incorporates the pick-ups, but these were not affected.  A consequence of trimming off the chassis meant there was a gap created between the die-cast chassis and the plastic keeper.  This gap just so happens to be the right amount for the NEM Kadee shank to be slotted in, and a small screw threaded in place to hold them. I use Kadees for all my models. The body only appears to need the funnel fixing screw to hold the body to the chassis firmly. All the wheels, chassis ends and copper wire down the side of the firebox were brush painted black. There was a little overspray at the base of the safety valve cover so that was cleaned off and some copper paint was applied to the lower half of the funnel coppertop.

The rear showing firing irons on the hooks and a fire bucket for something
different I noticed on one photo of the prototype
 All that was left now was weathering and glazing the spectacle plates.


This little model took more time to modify than I thought but I think it was worth it, bless its little soul!
