chat railcar is equipped with a Hollywood Foundry driving mechanism and the Billard T 80 has a BachmannDavenport chassis with the driving rods retained. The precious load A sugar beet railway cannot operate without sugar beet ! No type of seed available from pet shops for feeding domestic rodents was suitable for imitating beetroots. What could be done ? Well, make them ! That’s what Peter did, using air-drying plasticine. Each beetroot was individually shaped, then rolled on a coarse sheet of sandpaper to give it that specific texture. A painstaking task that endedup giving Peter raw fingertips, but which was worthwhile ! n The layout at a glance [Box]• Scale : 0 (1/43.5)• Gauge : 16.5 mm narrow gauge• Supply : Roco digital• Inspiration : northern France in the 1950s–1960s• Dimensions : 190 x 45 cm A box made to measure [Box] The layout is housed in a bespoke presentation caisson. The backscene is an arc-shaped sheet of thin plywood. A ceiling and anupper pelmet conceal the three fluorescent tubes. This atmospheric lighting is completed by two spots located forward of the layout, which provide a slight impression of sunshine and generate a few shadows on the scene. Located in the legs, a small shelf carries the Roco digital unit. All the wiring is concealed in the structure of the layout and nothing is visible. The name of the layout is displayed in adhesive letters on the khaki-coloured wood pelmet. [Captions]• A delightful Billard T 80 D is heading a set of sugar beet wagons from various networks and a TPT closed van, rather out of place in northern France. But such is modellers’licence ! • At the opposite end of the layout, a 0-6-0 T locomotive is seen entering the station, with a train of open wagons. This engine is scratchbuilt on a Roco BR 80 chassis.• On the right hand side of the layout, the sugar beet is loaded with a conveyor.• The wagons are weighed before being dispatched to the sugar mill.• Two turnout levers are located opposite the station building. They are from Caboose Industries, and feature a small in-built polarization switch.• The turnouts are based on the Shinoara range, fitted with copper-clad epoxy sleepers.• Passenger service is provided by a Crochat petrol-electric railcar, also from the TPT system. The turntable is a PecoH0m unit, re-gauged from 12 to 16.5 mm. It is operated manually by a crank handle and Meccano bevel gears.• All the layout’s engines ! • A new open wagon is still missing its bogies.• Small cameos add interest to the layout. Page 18 : History Branch lines in the Beauce ! The Pithiviers-Toury tramway lived by and for sugar-beet for a full 73 years. This almost complete focus on a single type of agriculture led to the creation of a great many agricultural branches allalong the main route. Text : Éric Fresné Illustrations : John Cosford (unless otherwise mentionned) Despite there being so many of them, these branches were seldom photographed by enthusiasts. All the more reason to show you the pictures taken by John Cosford in October 1964. As soon as the construction of the railway was studied, in 1889, traffic forecasts for the TPT showed that sugar-beet would steal the show. The first years of operations confirmedthis : sugar-beet traffic grew swiftly and became largely dominant. After 1908, it grew larger stillas agricultural branches began to be built, multiplying until the 1930s. At the railway’s prime, the mileage of these branches was triple that of the main route, and almost all the sugar-beet grown between Toury and Pithiviers was shipped from these branches. This also explains why the railway had such a large roster of engines : close on 30 locomotives in the 1940s ! Branches galore This system of multiple inter-connected branches generated a multitude of owners. Each large farmhad its own line. The length ranged from a few meters to several hundred meters. The sugar mills also built branches at their own expense. The mills being better off than the farmers, these industrial branches could sometimes be several kilometers long. The remainder of the system belonged to the TPT, which was technically in charge of everything. This included track maintenance and the installation of watering points needed for supplying the engines, such as at Beaulay. A role for each actor Operation of these private branches, like their maintenance, was a matter for the TPT ; the Toury sugar mill was alone in having obtained permission to run its own trains hauled by its own engines. The TPT locomotives hauled both the company’s own wagons and those belonging to the Toury sugar mill. At Pithiviers, the trains were taken over by the factory diesel shunter, which was not allowed beyond the exchange sidings between the factory and the TPT tracks. Each rake followed it obediently through the maze of the factory sidings and re-emerged later, empty of its load. n Monsieur Lambert’s 0-6-0 Ts [Box] Arthur Lambert, the general manager of the Toury sugar mill, was planning in 1913 to install his own 60 cm gauge sidings, connected to the TPT. WWI and the commandeering of the stock earmarked for this job jeopardized the plan. But the importance of sugar-beet industrial produce for the war effort soon led Lambert to renew his request. And he was quickly successful. Extraordinarily for the period, he even managed to order two type 17 Decauville 0-6-0 T engines, « Simone » and « Suzanne », at a time when the Corbeil factory was working exclusively for the army. These two locomotives proved highly successful at Toury. After the war, more engines of this type joined them on the railway. [Box] Do not miss the book « 70 ans de chemin de fer betteraviers en France » (« 70 years of sugar beet railways in France ») available from the LR PRESSE shop, price 29.90 euros, code BETTERAV2 [Captions]• On a damp autumn Saturday, John Cosford set out to chase sugar beet trains through the countryside, north of the main TPT line. 17 October 1964.• The chase began at Beaulay. But the train had started its journey well before, on tracks belonging to the Pithiviers sugar mill. Industrial sidings separate from the factory, and simply connected to it by the TPT tracks. 17 October 1964.• The meaning of the word « ballast » had long been forgotten ; grass and mud played the part. 17 October 1964.• The Pershing open wagons belong to the Pithiviers sugar mill. This is obvious from their extended side panels, their numbering and their trapdoors. 17 October 1964.• The train finally stops at the junction for the branch. The crew awaits the order to proceed before moving onto the main line. Meanwhile, John has parked his Austin-Morris 1100 before resuming the chase. 17 October 1964.• Permission has been given at last… by phone to Bitry station nearby. The train departs for Pithiviers, its terminus. 17 October 1964.• At Pithiviers, John followed a second train, similar in appearance to the previous one. The engine is different. Here we have N°5-3, an Orenstein & Koppel 0-10-0 T with Luttermoler gearing. The train has passed the TPT station and moved into the TPT/sugar mill exchange sidings, across the SNCF goods yard. 17 October 1964.• Beyond these exchange sidings, this odd looking machine will be in charge. This is a Drewry-Baguley artillery tractor, built for the French army, and bought second-hand by the mill. 17 October 1964.• At the entrance to the factory, 60 cm and standard gauge are closely entwined : an opportunity to display the rolling stock loading gauge differences. 17 October 1964. Page 22 : Technique Coachwork for the Atlas Billard A 80D In the first part of this article, we dealt with motorizing the Atlas Billard A 80D. The time has come to move it into the coachwork shop and make it more realistic. Text & illustrations : François Fontana As we have seen, this model isn’t prototypical. Its width is that of the short units, and its length that of the narrow units ! I opted to retain these somewhat inaccurate dimensions. On the other hand, I will implement a few simple modifications that will turn it into « my very own » Billard. An eclectic list• The « snail horns » : amputation of these totally incongruous appendices. The holes will be filled and sanded.• Removal of the warning horns : filling and sanding of the holes.• Removal of improperly located headlights : the holes will be filled and sanded.• Removal of one of the fuel filler caps : filling and sanding.• Removal of the two handrails : fabrication of six new ones. Re-drill to the right dimensions and fit.• Sand the mould joints. Once the coachwork has been completed, it’s time to paint the model. Clean it carefully with soapy water. Apply a coat of primer and, without touching the body with bare fingers, mask the lower part and paint theupper part in cream. Once dry, do the opposite : mask the top and paint the bottom in railcar red, taking care to retain the fine printed markings. The frames of the small windows are then painted in aluminium colour. 4
From this long list of tasks, the most frequent job is clearly filling, sanding and masking. Sanding Coarse grain, medium grain, fine grain. Which to choose ? Coarse grain sandpapers (of 80, 120 type) remove more material, but often leave scratches and even deep furrows that must then be smoothed down. They must be used only for preliminary work, on a hard material such as brass. To be avoided altogether with plastics. Medium grain (from 200 to 400) can be used for preliminary work, prior to finishing. This is the type of abrasive found on cardboard nail files, for example. Providing you work gently, they can be used on plastic. Fine grain papers (600, 800) are perfect for finishing the work. Quality will be better still if they are used with water, meaning by steeping them regularly in a jar of water placed on the workbench. By doing so without pressing too hard and using circular movements ; a perfect finish will be ensured. Once the sanding is completed, the body is, of course, washed in clear water. Filling and applying primer Before any filling is performed, the surfaces must be clean, free of grease and dry. I use domestic alcohol and a soft cloth or paper tissue. Depending on the material, I use different types of filler. Two-part fillers of the Tamiya putty or Andrea Sculpt type are very well suited to supporting stress when there is a lot of work required. Resin and catalyst are thoroughly mixed in equal parts. The putty is applied with a spatula, spread like butter over the hole to be filled and smoothed as best possible. This type of product doesn’t shrink when setting, so there’s no need to apply too much of it. Once dry, the putty is sanded. One part fillers. They are drawn directly from the jar or the tube, and are well suited to small repairs, but they do shrink a little when setting, meaning that a bit more needs to be applied. Once dry, they must be sanded delicately, as they do not always hold as wellas two-part products. It’s often necessary to finish off the work by applying a surfacing primer (also known as « finishing primer ») with an airbrush (such products are also available in aerosol cans from the LR Modélisme range) to ensure a perfect finish prior to painting. Once dry, this primer is if necessary sanded to obtain a truly smooth surface. Masking Several materials can be used for masking : liquid gums (Humbrol Maskol for example) and adhesive tape (Tamiya makes a very good one). For this specific job, I willuse thin-film tape. Once in place, it sticks well to the surface, paint doesn’t run under the tape as is the case with thick-film tapes. The adhesive masking tape is placed on a perfectly clean surface, with a very slight tension. It must be stuck down carefully, but without excess, to avoid any risk of tearing off the undercoat on withdrawal. Once the paint has dried thoroughly, the tape is peeled off, in other words by pulling it along an axis that is parallel to the painted surface. This is the only way to ensure the paint itself isn’t peeled off ! n A drilling template [Box] I made new handrails out of brass wire : a length of 0.6 mm diameter wire is held at both ends in a loop of 0.3 mm wire held in place by a drop of solder. I used a small template to make these handrails and for drilling the body. In this way, I’m sure they are all identical and all properly located. The template is made out of thick card. The holes are drilled 2 mm from one edge. The top of the template is aligned along theupper body seam cover. Simply put it in place to ensure that all the holes will be drilled in the right place.• Template• Body seam cover• The template is used for drilling the holes on the body sides.• The same template is used for assembling the handrails. Assembling the driving chassis [Box] A reader asked me how I glued the plastic of the Tomitec driving chassis ? Whatever method is selected, de-greasing is essential. But I have already said this… So, after a light sanding with medium-grade paper, to make the surface of the plastic more catchy, I de-grease. Then I glue with a tiny drop of cyanoacrylate adhesive. I have not identified a plastic adhesive that attacks the material – probably a type of polyamide – used by Tomitec ! 1 mm thick plasticard shims are fitted between the sides cut off the Atlas model and the Tomitec bogies. The chassis is screwed into two 1 mm thick plasticard shims that are glued inside the body, 7 mm from the bottom.• Shims located 7 mm from the bottom of the body.• Partition• 1 mm thick shim• Original bogie frames• The bogie frames are glued onto the Tomitec bogies. The chassis is screwed into two shims glued inside the body. 5 [Captions]• Before starting work, the model is completely dismantled. The side glazing and the detailing parts are held in place with such tiny amounts of adhesive that they come off at the slightest pull. The end glazing is simply force-fitted.• First job : with a scalpel and a Swiss needle file, I remove the traces left by the mould joints.• A cardboard file is ideal for starting the work.• Finer sanding is done with fine-grade wet coackmaker’s paper ! • The putty is applied with a spatula.• Once sanded down, the hole has vanished.• A simple card support is slid into the body ; the masking tape is carefully applied along the body seam cover.•To remove the tape without damaging the paint, it must be peeled off over itself, applying slow and regular traction. Page 26 : Under the magnifying glass 0n18/09. Small diesel for small track The British artisan Backwoods Miniatures has released, in its resin kit range, a freestyle diesel tractor in 09, designed to fit onto an N scale Kato driving chassis. Text & illustrations : François Fontana A fine-looking box, fine-looking parts, a clear and accurate set of instructions in English, a straightforward assembly process and to sumup, a pleasing and reliable item of motive power, such are the qualities of productions by Backwoods Miniatures. n The model [Box]• Manufacturer : Backwoods Miniatures• Scale : 1/48 for 9 mm gauge track• Mechanism : Kato 11-103 driving chassis• Price : Kit 19 £, Kato chassis 35 euros [Captions]• As is customary with castings, the first job consists in cleaning them. I usually steep them for a few minutes in acetone. Then you must cut off the injection sprues with a sharp blade, and smooth down the areas with a fine file.• Some parts have a tendency to warp, but don’t panic : simply steep them for a few minutes in boiling water, then clamp them flat on a bed or straighten them between your fingers. Once they have cooled down, the parts will remain perfectly flat ! • Cyano adhesive is used to glue resin. The model fits onto an N scale Kato chassis, which ensures perfect running qualities. After having carefully cleaned the kit, it is given a coat of primer from a spray can, then a coat of acrylic paint. Page 27 : File 50 years Egger-Bahn Egger-Bahn turns 50 Fifty years ago, at the Nuremberg International Toy Fair, model railway professionals discovered a diminutive H0 diesel locomotive and two trucks, running on an oval of 9 mm gauge track. Egger-Bahn was born. The company’s growth would be stunning, and its fall equally swift. But the « sauce » had taken ; narrow gauge modelling for all was there to stay. The brand has since become an object of passion, sometimes beyond reason, and Theodor Egger’s tiny trains have bred many descendents. Page 28 : History Before Egger-Bahn, in France What was there on the modelling market before Egger-Bahn ? Denis Fournier Le Ray reviews a few models that are representative of productions ranging from high quality modelling to toys. Text : Denis Fournier Le Ray Illustrations : Denis Fournier Le Ray, François Fontana This may seem surprising, but the first French narrow gauge models actually appeared 85 years ago ! One can indeed consider that the first manufacturing took place in 1928, when the Edobaud company (contraction of Edouard Baud), located in Oyonnax in the Ain département, showed in its catalogue a work train in a scale close to 1/20, which could run on 32 or 45 mm gauge track by regauging the wheels on the axles. A full range was available : electric tractor (with three-rail, then two-rail supply from 1931), wagons, track and accessories. Construction was very sturdy : the 1928 catalogue specifies that the bonnet of the tractor was 2 mm thick sheetmetal ! This train enjoyed a very short life and vanished from the company’s catalogues in the mid-1930s. It has become a very rare collector’s item.
