Why do railroads use signals?

A common question newcomers to model railroading ask is “Why do railroads use signals?” The quick answer is to keep trains moving safely. But the topic of railroad signals deserves more of an explanation. The evolution of railroad signals When trains are running in the same direction on the same line, in opposite directions on […]

Why do railroads use catenary?

When you think about electrified rail lines today, the first thing that probably comes to mind is Amtrak’s Northeast Corridor. But in the first half of the 1900s, before the start of the diesel era, railroads used electrified lines to move freight and passengers. Examples in the east included the New York, New Haven & […]

Why did railroads use train orders?

Scan of train order with information written in pen.

If you’ve read Model Railroader or many of our books and special issues, you’ve probably seen references to timetable-and-train-order operation, or TTTO for short. Employee timetables (ETT) that governed TTTO operation listed station names, mileposts, train numbers and classes, departure and arrival times, and operating instructions, among other items, to govern train movements. So why […]

Why do railroads use towers?

What are railroad tower operations? Railroad tower operations can have at least two meanings. One is what happens inside a tower, or more specifically, an interlocking tower. The other is a way of running a railroad, by using the operators in interlocking towers to control traffic through specific points of the railroad. So, why do […]

How to keep your model railroad layout clean

It’s all-too-easy to turn your layout into a depository of dirt-carrying items and cover it with cookie crumbs!

Tips for keeping your model railroad layout clean: A clean layout is fun to run, fun to work on, and fun to look at.  Unfortunately, the three D’s – dust, dirt and debris – are in season all year long and can make keeping a layout clean a constant, time-consuming job. Here are a few […]

OS block control using an Arduino microcontroller

The following project is an update of Gary D. Patterson’s “Simplified CTC signals” in the July 1988 issue of MR. Bringing the project up to date was a large endeavour. The block control project now incorporates “all” solid-state components controlled by an Arduino microcontroller. I refer to this updated article as “CTC Signals 2.0.” The […]

Common methods for uncoupling cars

Photo showing two flatcars and assorted uncoupling items.

Automatic knuckle couplers have been a part of model railroading for more than 60 years. Not only do these couplers look more like what you see on full-size locomotives and freight cars, they’re easy to install and use. You can learn more about them in my articles on HO and N scale couplers on Trains.com. […]

12 train sets for the holidays

If you’ve read Model Railroader magazine for any length of time, you’ve probably noticed the hobby journey for many of our authors started with a train set. For baby boomers, born between 1946 and 1964, the set was often produced by Lionel or American Flyer. Fast forward a generation or two, and those sets were […]

Last days of the last car on the train: the caboose

A model red caboose leads a shove of hoppers

Cabooses (no, not cabeese) were a common occurrence on freight trains throughout most of the 1900s, yet we rarely see them today. Why is that? When did they stop operating? Where did they go? And lastly, how can I model the last days of the caboose on my layout? Why? In one word: technology. Advances […]

Short Amtrak consists of the 2000s

I hope you’ve enjoyed the tour we’ve taken of Amtrak’s short consists throughout the railroad’s history. Starting with the modern era, we then went back in time to the 1970s, then the 80s and 90s. This month, we’re looking at my favorite era of short Amtrak consists. Is it because that’s when I grew up? […]
