Model Engine Works: 009 Fowler Style Tram engine

This is a “what might have been” Fowler style steam tram engine, based on a Fowler traction engine’s boiler and funnel, the cab of a steam wagon, assembled on a footplate to go on rails. The result is a reverse running engine cab first with a large forward facing lamp, but it looks equally well as a small engine with a high mounted boiler and oval cab windows running forward. It would probably be used in various industrial settings or on small roadside tramways around the latter part of the 1800s.

I had a sample printed by Shapeways in Fine Detailed Plastic. When this arrived, I soaked it in Petroleum organic solvent – paint thinners (“White Sprits” in the UK) in order to remove the wax support residue left from printing, then I washed it in warm soapy water this should be left to fully dried before painting. I then used a grey spray primer to prep the model for finishing. In some areas, it may be necessary with some models to remove print lines from the surface, and this can be done with a burnishing tool - I use a hardwood stick with a rounded point to get in the tight spaces. Do these processes before separating the print into its component parts so you will be less likely to lose any of the small pieces.

Wirework and details

The next job was to add the handrails to the side of the cab. I obtained the wire for these from a supplier on eBay. I formed the cab side handrails as small staples bent with pliers to the right size and fitted into the pilot holes supplied on the model. The handrails were then glued in place with Cyanoacrylate (super) glue.

The smokebox on the model is a simple top-hinged affair so no dart will be needed.

The new Kato 11-110 chassis are a welcome improvement on the later version of the 11-104 which they replace, having more weight, different gearing, a brass flywheel and much smoother electric motor. They fit within a similar opening as the original. They do not need as much ballast to run well, but adding some is a good idea for traction. I used small strips of lead fitted along the inside of the skirts, also on the sides of the water tanks keeping this as low as possible to keep the engine's centre of balance as low as possible.

The couplings I used on this model were from RT Models ref 4NLP005 white metal Penryhn Locomotive couplings. Others could be fitted such as Greenwich or NEM couplings. The aperture in the buffer beams will take the Peco 103 NEM pockets and couplings.

Painting and finishing

Once all the additional bits and details were added I gave the model a final coat of grey spray primer and made sure all was ready of the final paint finish. For this model I was trying some Tamiya acrylic paints, I had decided this was going to be an industrial-looking model and finished in black, so I used the XF-85 Rubber Black on everything except the front buffer beam, which I used XF-7 Flat Red. Using these I noticed that each colour has a different consistency, the XF-7 being thin and needing several coats were as the XF-85 was smoother, creamer, and needed fewer coats. I picked out some details like the window frames in a brass enamel paint and the cab handrails I left in the brass wire to match. The cylinders, couplings, lamp, and smokebox door were painted in a gunmetal metallic enamel paint.

I wanted to add numbers transfers to the model so I applied a coat of clear gloss enamel varnish to the areas these were to be placed. This is a better surface to apply the transfers to and allows you to adjust and position them much easier. I used “Fox” 2mm waterslide transfers in gold for the cab sides and rear only. Once this was completed, I applied a coat of matt enamel varnish to the whole surface of the model, this also seals the transfers in place.

The final additions to the model were to add some real crushed coal to the two bunkers at the rear of the water tank next to the cab, by adding PVA glue to the bunker area and then tipping a small amount of the coal over this using a tube as a micro shovel to place it correctly.

In the past I have made some working lamps from white Plasticard and rhinestones of clear and red plastic and I used one of these for the rear running lamp for this engine and a larger rhinestone for the large lamp on the cab.
