Building an HO scale Locomotive from Wood

Building an HO scale Locomotive from Wood and Card
(Model Railroader, May 1972)


Back in the days before CAD/CAM and cheap injection molding, model locomotives of specific prototypes were rare. The makers in Japan and Korea supplied limited numbers made with brass. The first examples in the late 1940s and early 1950s were cheap, but by 1972 quality had improved and prices had risen to two to four weeks average pay. Most modellers made do with repainted cheaper mass-market models that were “close enough”. These cost a couple of days pay. Adding details representing a particular railway’s house style helped the illusion. But if you wanted something as close as possible to your favourite road’s engines, you had to scratchbuild.

Culling masses of obsolete paper recently, I came across an article by A. E. Sima Jr (aka Bud Sima). He described how his poor soldering skills prompted him to try his hand using wood and card for building a locomotive. He wanted a model of the Maryland & Pennsylvania’s heavy Consolidation (2-8-0) steam engine. He bought a Varney 2-8-0 to adapt, but when he took it apart in preparation for repainting, the boiler casting encountered the basement floor at a high speed and broke. Bud was left with a mechanism. He decided to make a locomotive body to fit.

The article describes how he did it. He drilled out a suitable piece of wood dowel (to make space for the weight), and cut out a space at one end so it would fit over the motor. He cut cab sides from sheetwood, but did use sheet brass for the cab roof. He made some details with wood, card, wire, and sheet brass, and bought others. In those days, several manufacturers offered dozens of details such as bells, smokestacks, feedwater heaters, steps, brake cylinders, and so on. The tender body was cut from a block of wood and wrapped in card. A dress snap made the electrical connection between tender and locomotive. So “for a surprisingly small outlay of cash”, Bud got what he wanted. I’m sure he inspired others to try their hand at scratchbuilding too. Model Railroader helpfully reprinted its plans and photos of the Ma & Pa locomotive.

Bud writes in a friendly conversational style. The photos and diagrams are adequate for the purpose. Nowadays, we would see a bulleted step by step description, with more photos. Anyone who’s put together a handful of kits would have little trouble emulating Bud’s project. The modern builder would use plastic tube and sheet material instead of wood. There are far fewer details parts available, so fabricating them might be a major challenge. Even so, Bud’s article could be just the inspiration needed. It’s available online for any subscriber to Model Railroader’s online services.

I enjoyed re-reading Bud’s story. ***
