What is HO scale? Read on.

Let’s play Jeopardy. Answer: Measuring at a 1:87 scale ratio relative to the real thing, this is the most common and popular scale of model railroad in the world outside of the United Kingdom. The question, of course, is, what is HO scale. It’s not a reference to Christmas or anything like that. HO is an acronym for “Half O,” a reference to its approximate size relative to the train scale it overtook in popularity around 60 years ago.

HO scale trains, scaled at 1:87 scale, are the most popular size and scale of model railroad in most of the world since the 1950s. It uses realistic 2-rail track and DC power.

Is oil conductive? Sometimes, actually

Is oil conductive? It’s a frequent point of debate among model railroaders. But generally speaking, oil isn’t a very good conductor. That said, oil can be a good conductivity enhancer, even though it’s not a very good conductor on its own.

Here’s how to use oil to improve conductivity in electrical applications. This can work whether you’re talking household current, or low-voltage applications like you find in model railroading.

Hi rail in model railroading

Hi rail in model railroading

Hi rail in model railroading refers to the use of traditional Lionel or American Flyer trains in a scale-like setting with realistic scenery. Hi-rail is a railroading term, but in real railroading it refers to a vehicle that can operate either on tracks or a regular road.

Sometimes hi rail is spelled high rail, with or without a dash, and sometimes combined into a single word, highrail or, more frequently, hirail.

Sizes of model trains or model train scales

Sizes of model trains or model train scales

Model trains come in a variety of sizes to fit the space you have available. Or, to cram more stuff into the space you have available. Here are the common sizes of model trains, or, if you prefer, model train scales.

Sizes of model trains, or any other model, are measured in scale. Scale is a ratio of the model’s size relative to the real thing. Sometimes people will refer to gauge as well, which relates to the track, rather than the train.
