Master Model Railroading

A system that allows independent control of multiple locomotives on the same track using digital signals sent through the rails.

Track switch that allows trains to move from one track to another. Also called a switch or points (UK).

Two or more locomotives coupled together and operating as a single unit, often used for heavy freight operations.

The structural framework that supports your model railroad layout, typically made of wood.

The foundation layer under track, often cork or foam, that provides cushioning and realistic elevation.

Techniques used to make models look realistically aged, dirty, or worn through paint and other methods.

Flexible sectional track that can be curved to any radius, as opposed to fixed-radius curved sections.

The primary route on a railroad, typically featuring through traffic and higher speeds.

A secondary track parallel to the main line, used for passing or storing cars and locomotives.

Hidden track sections representing off-layout destinations where trains originate or terminate.

A spiral track arrangement used to gain elevation between layout levels in a compact space.

The ratio between the model size and the real prototype, such as HO (1:87) or N (1:160).

The distance between the inside edges of the rails, with standard gauge being 4 feet 8.5 inches in real life.

The real railroad, locomotive, or car that a model is based upon.

Combining parts from multiple model kits to create a unique or more accurate model.

An electrically isolated section of track used for signal control or detecting train presence.

The finished front edge of the layout benchwork, often painted and used to mount controls.

A painted or printed scene behind the layout that creates depth and hides the wall.

The mechanism that connects rolling stock together. Knuckle couplers are standard in North America.

A DCC decoder with built-in speaker and sound effects replicating the prototype locomotive.

Track gauge narrower than standard, often 3 feet or 2 feet, used in mountainous or mining areas.

Exact-scale HO modeling where wheel and track dimensions match the 1:87 ratio precisely.

Running a layout like a real railroad with car routing, train schedules, and switching tasks.

The tightest curve a locomotive or car can negotiate without derailing.
