I’m thinking of making a small layout in G scale with a engine stall as focus. Because i live in Belgium i have no idea what the messurments are for the building and for the sectional door. Can sumbody help me here, please if possible in metric system.
For one on a branchline, this one would be the type most likely used, unless there was an older structure available in that locale, capable of accommodating the locomotive which you have in mind.
According to Walthers, the structure is 30 X 60 N scale feet (9.144 X 18.288 meter). Since there are so many different ratios involved with whatever G scale is, you’ll have to figure out the conversion yourself.
What year do you plan to model? And what type of engine do you plan on putting in it?
If you’re doing anything near current, the engine house is going to have to be larger than 60 ft. Even an old GP38-2 that’s been relegated to switching duties is 59.5 ft.
Based on the pictures you posted, the doors are 20-25 feet tall and maybe 15 feet wide. That would clear a modern large diesel, definitely clear a GP38-2. You can estimate the rest of the structure dimensions based on that. And then convert to your scale to get the actual size you need to build. Check it out with a mockup (cut the door opening in a piece of cardboard, for example) to make sure it really does clear the actual model. A single stall on some shortline somewhere will be a very simple steel structure if built new, or it could be a repurposed older structure with different construction and perhaps the original end replaced with the large door if it didn’t already have one.
The Union Pacific U25B’s were built in 1961 and 1962. They were retired in 1972. During most of that time, they were likely in mainline service. So seeing just one at a small enginehouse would be very unusual.
BUT.
Some of them ended up on the OC&E, a small railroad that went east out of Klamath Falls, Oregon. Roughly, in 1976. And they, again roughly, lasted until 1991. IF you wanted to repaint and reletter yours, they were done in this attractive color:
Should you NOT wish to do a repaint, you could argue that they just arrived and have to be put to work right away.
Anyway, here’s a picture of an OC&E enginehouse:
Note the main doors, and above, the auxiliary doors for the craneway. You can see the building has some length.
Being black and white, this building might have been gone by the time the U25B’s arrived. Or might not. But you can see a typical enginehouse on a railroad where “your” U25B ended up. As OC&E 7605. For awhile.
You can learn more about the OC&E from the book by Jeff Moore: “Eastern Oregon Shortline Railroads”.
Weyerhauser (a big lumber company) also got some, and they were also painted nicely. There’s a lot of material a
A 1/29 U25B is a bit over 25" long. I wouldn’t be surprised if what Marc is after is the smallest engine house that works and doesn’t look stupid.
So, going back to full size dimensions, the overall length of a U25B is 60’-8" (over couplers). The major door size I would keep. If one adds 4’ all around, then the minimum interior dimension is 14’ x 68’-8". If one then adds a foot for wall thickness, then the minimum exterior dimension is 16’ x 70’-8". I think an enginehouse without a shop is just plain weird. So I would add an arbitrary 14’ to the width for the shop, office, etc. Thus 30’ x 70’-8". Which is 12.5" x 29.25". Or .3m x .75m. I’d also skip the craneway and go with a flat roof. Which would give an external height of 26’–10.75"–.27m.
Which is suspiciously similar looking to that Pikestuff building–same width, 11’ longer.
That said, I’d call this a minimal building, and try to add “something”. First would be another major door out the back. A bigger (wider) shop would be nice, too.
