Q: What is HOn3 scale? If it uses HO scale track (1:87 gauge), it seems the rolling stock must be scaled wider and taller. Conversely, if I modify an HO scale/gauge locomotive for narrow gauge, I’ll need to build new, narrower track. Help me understand this. – Mark Dice A: Hi, Mark. Your second guess is the […]
Q: I’m planning on making steel slab, H-column, and I-beam loads for my run through freight trains. What is the width, length, thickness and height of the load for these structural steel loads? – James Shepard A: Hi, James. You asked a similar question not long ago, which I answered in my January 2023 “Ask […]
What tools does a model railroader need? Q: What are the tools needed to take an empty room to a full working model railroad? My focus is to build a layout with the best scenery, from streets to tall mountains and everything in between. – Carroll Shirkey, Seattle, Wash. A: Many beginners are left wondering […]
Q: I am in the initial phases of planning an N scale model of the Duluth & Northeastern Railroad in Cloquet, Minn., circa 1998. I have information on their locomotive roster, which consisted of three EMD SW1s and an EMD SW1000. However, I’m not having much luck locating information on the Duluth & Northeastern freight […]
Q: I am researching and modeling Jefferson, Ohio. There are a number of buildings that are constructed from glazed block, as in this photo. I’ve seen the hobby manufacturers make all kinds of brick, stone and block sheet material, but I have not found material that looks like this. Do you have any ideas on […]
Q What is the meaning of tank car color schemes? Is there a color code? Some tank cars have a contrasting horizontal stripe on the middle section of the tank, while other tank cars are painted a solid color. Since some tank cars carry hazardous or toxic chemicals while others carry edible materials, are the […]
Q: I’ve read the articles on how to patch out locomotives and rolling stock, but how often are these techniques used by cash-strapped short lines? It seems a lot easier (and cheaper) to slap a patch on a new locomotive and get to work than repaint a used locomotive. – Michael Schlobohm A: Prototype railroads, […]
Q: Way, way back in the 20th century, I think in the 1980s (though I’m probably wrong), Model Railroader ran an article about making your own coupler height gauges in the various scales, including TT scale. Can you advise which issue that was? None are available in TT today, and I could use a couple on […]
Q: I was given an older model of a reefer car that has hatches across the whole roof instead of on each end (see photo above). Is this a special type of reefer for handling a specific cargo? – Wes Barteck A: Though that kind of refrigerated car is more common north of the border […]
Q: Reading Jerry Dziedzic’s essay on “Turning waybills into dollar bills” (August 2023) made me realize that I don’t know anything about how prototype railroads handle the inspection and shopping of freight cars. Are cars sent in for inspection, paint, and maintenance at fixed times, or after a certain number of miles, or only when a […]
Q: I’m planning a small layout based on The Bay Line (BAYL), a north Florida short line, focusing on the Cottondale diamond crossing and CSX interchange. I found a fascinating picture of the diamond near the interchange in 1989, which shows a grade crossing-type gate across the railroad track just before the diamond. What would the […]
Q: I’ve been given several HO scale locomotives that unfortunately came without boxes or information about whether they were DCC equipped or not. Most are very nice, higher end models, not entry-level. Is there any way to safely find out if each locomotive is DC or DCC without taking off the shells? Even if I do remove […]
