Let’s Build A G Scale Engine House & Carbarn

July 18, 2009

Scratchbuilt G scale F scale Engine house

This remarkably beautiful structure could be your next G scale structure. A building like this could easily be a car barn or engine house depending on the type of details you’d want to add to the basic structure.

This particular engine house is built to last, utilizing high quality lumber and plenty of titebond, screws and nails to keep it together for years to come. It also has recieved two layers of primer and 3 layers of state-of-the art housepaint. (We’ll discuss paint later).

Our building here is sparsely detailed to allow the future owner to detail it to fit his needs. With the addition of normal sized doors and windows along the side it could look even more impressive. Spend some time adding some board-and-batten woodwork, and some victorian architectural detail and you could really make it stand out. Add some G scale smoke jacks and rigging wire and you’d have a top-notch engine house.

Based off of plans found at a train show, I modified the drawings to fit the space I had, which was roughly 2X4 feet. The building itself is 19 5/8ths inches wide and 44″ long, with an inch roof overhang all around the structure for drainage and improved looks.

So Follow along in the next couple of posts as we build this fantastic engine house!

G scale engine house front walls

First we cut the front & rear walls out of 1/2″ plywood with a Jigsaw. The 2″ round hole in the front was cut with a drillbit hole attachment.

Next we cut the walls from more 1/2″ plywood and NOTCHED the top of the board to match the slope of the roof, which is crucial.


Make sure to cut the holes for the building out carefully, as you’ll need to use them for snug-fitting doors for all three stalls. We cut the 1/2″ thick pieces in half and filled and sanded them smooth.

Next we cut the roof framing from recycled 1/2″ lumber and notched the roof peaks in a special fashion, as seen below, for extra strength.

Follow the arrow to the roof brace mounted about an inch below the roof line, so the roof frame, when lowered into place, will sit flush against the beveled side walls for a seamless fit.

IF you want one just like this, we have decided to offer it to “Interacting with Miniature Railroading” readers for just $450 plus shipping.

Stay Tuned For Part Two!
