Model Railroad Hobbyist is a monthly online-only magazine about, as the title suggests, model railroading. The quality of the content is very high–I’ll argue the writing, editing and photography give Model Railroader and/or Railroad Model Craftsman a run for the money. I really think which is best in any given month has more to do with the reader’s interests than anything else.

If you’re interested in model railroading or any other hobby that involves trains, dioramas, or both, it’s worth bookmarking and visiting every month. Perhaps more frequently, as you peruse back issues for gems you missed in the past.

## The Observation Car

I’ll argue that model railroads and toy trains are separate but related hobbies. That said, I still enjoy good model railroading material. I can still steal ideas from them and adapt their techniques.

Late last year, noted model railroaders Dave Frary, Doug Foscale, and Jimmy Deignan started a podcast called The Observation Car. If listening to three veteran modelers sit around and talk shop once a month for a little over an hour sounds interesting or useful, it’s worth bookmarking. They haven’t done their February podcast yet, but I’ll be watching for it. In the meantime, they have three podcasts up to listen to.

## A model railroad scale conversion chart

Plans in model railroad books and magazines are often in a different scale from your favorite. Having a model railroad scale conversion chart helps.

I’m into O scale and the rest of the world, it usually seems, is not. Dimensions for published plans are almost always sized to HO scale, or even S scale of all things. Of course, after A. C. Gilbert imploded in 1967 and took American Flyer with it, it seemed like the “S” is S scale stood for “scratchbuild,” because building it yourself was the only way you were going to get anything, so I guess that’s fair.

Here’s a cheatsheet you can use to convert measurements from one scale to another.

Assumptions: O scale is 1:48, G scale is 1:22.5. If you use a different measurement for either scale, I’m sorry. This won’t be much use to you.

 G Scale O Scale S Scale OO Scale HO Scale TT Scale N Scale Z Scale G Scale 213% 284% 339% 386% 533% 711% 977% O Scale 47% 133% 158% 181% 250% 333% 458% S Scale 35% 75% 119% 136% 188% 211% 289% OO Scale 30% 63% 84% 115% 158% 211% 289% HO Scale 26% 55% 73% 87% 138% 184% 253% TT Scale 19% 40% 53% 63% 73% 133% 183% N Scale 14% 30% 40% 48% 54% 75% 138% Z Scale 10% 22% 29% 35% 40% 55% 73%

Find your scale in the table along the top. Then scroll down to the desired scale and find out the factor you need to enlarge or reduce. So, if, say, I have HO scale plans I want to enlarge to O scale, I run across the top to HO, then down to O scale, and see that I need to enlarge the plans to 181%. If I have O scale plans I want to reduce to S scale, I run across the top to O and down to S, and see I need to reduce the plans to 75%.

You can also do this if a building you want exists in kit form for a different scale. Measure it. Then do the math based on the chart to figure out what size to build everything for your scale of choice.
