Even though I do a\u00a0LOT of scratch building and brass bashing for my own railroad, in support of both my D&H and Erie fetishes (you gotta roll your own if your’re going to model steam\u00a0for either of those roads), I also regularly take on commissions for other clients from both the U.S. and overseas.<\/p>\n

This\u00a0past spring\u00a0(2010) I took on a box-stock US Hobbies PRR\u00a0I1s project. The client, a physician from New England, wanted this loco as\u00a0accurately detailed as was humanly possible. Using detailed images from the period for this loco, I\u00a0took this generic Penn I1s and totally reworked it into\u00a0ultra-detailed PRR I1sa #4390, as she appeared in 1953.<\/p>\n

Partial cab interior and boiler viewed from Fireman’s side (note the addition of the reach rods from the starter valve and the injector on both the steam supply and water dump sides of the valve). This is how the Fireman controlled these components without leaving the cab…<\/p>\n

Engineer’s side front end showing many additional details, including the Turbo-Generator exhaust steam pipe and standoff, that connects to the generator and exits along side the stack (an often overlooked detail)…<\/p>\n

\"\"<\/a><\/p>\n

Boiler is regularly test-fit to the chassis during the detailing process, ensuring that proper running clearances are maintained between the new boiler details and all moving parts, i.e. drivers, rods, valve gear, etc…<\/p>\n

Belpaire topside details showing the addition of the two reach-rods and rod-guides\u00a0that control component steam supply. The rods penetrate the front cab bulkhead, and end over the top of the crew’s head. Their red handles can be seen in the very first image in this section.<\/p>\n

The arching whistle chord\u00a0and guides from the whistle’s accuating lever and back to the\u00a0Engineer can\u00a0also be seen. This chord is made from 0.005 brass wire that has been anealed, formed and re-hardend, which allows it to take on\u00a0and maintain this shape.<\/p>\n

Here are all the components cooling, having come\u00a0fresh from the paint oven.\u00a0 All parts are baked at 175 degrees for three hours to cure and harden the paint. Paint for this model is ScaleCoat PRR Brunswick Green (DGLE). The paint is not applied directly to the primer coat, as it is too green from the bottle. Instead, after priming, the entire loco is\u00a0first painted semi-flat black, and that coat is then\u00a0baked. 48 hours later, the Brunswick green is applied. \u00a0Doing this dramatically darkens the green top coat to a near-black. Later, after lettering and clear, matte\u00a0top-coat, this near black color throws off green hues in both natural and artificial light, just as a fresh, PRR paint job would have done on the prototype.<\/p>\n
