Scale Model Trains

Scale model trains are one of the most enduring and rewarding hobbies in the world. Whether you're drawn to the precision of a compact layout or the grandeur of a sprawling multi-level railroad, the hobby spans a wide range of scales, themes, and skill levels. At MPM Hobbies, you'll find dedicated sections for every popular gauge alongside the scenery, electronics, and accessories needed to bring any layout to life.

Explore by Scale

Model railroading is organized by scale — the ratio of the model to its real-world prototype. Each scale has its own track gauge, community, and product ecosystem. Browse our dedicated scale pages to find locomotives, rolling stock, and track systems suited to your layout goals:

  • Z Scale Trains — The smallest commercially available scale, ideal for highly detailed layouts in compact spaces.
  • N Scale Trains — A widely popular choice for modelers who want expansive scenes without requiring a large room.
  • HOn30 Scale Trains — Narrow gauge modeling in HO proportions, well suited to logging, mining, and industrial themes.
  • HO Scale Trains — The world's most popular model railroad scale, offering the broadest range of locomotives, cars, and accessories.
  • On30 Scale Trains — O scale proportions running on narrow gauge track, popular for character-rich, story-driven layouts.
  • S Scale Trains — A mid-size scale with a devoted following and excellent prototype fidelity.
  • O Scale Trains — Classic, highly detailed models favored for both display and operating layouts.
  • G Scale Trains — Large, durable models built for indoor display and outdoor garden railroads.

Scenery & Layout Accessories

A great layout goes beyond track and locomotives. Realistic scenery transforms a model railroad into a living scene. Explore our accessory categories for everything needed to build terrain, detail structures, and animate your layout — from ground cover and rock castings to ballast and vegetation.

Browse scenery categories including Ballasts, Bushes, Shrubs & Tree Foliage, Ground Coverings, and Rocks & Rock Facing — all curated for scale accuracy and layout realism.

DCC Electronics & Digital Control

Digital Command Control (DCC) has transformed model railroading, enabling independent control of multiple locomotives on the same track with realistic sound and lighting effects. Explore our Electronics & DCC Systems section for decoders, controllers, and digital accessories suited to layouts of every scale and complexity.

Maintenance, Hardware & Layout Construction

Keeping your railroad running smoothly requires the right maintenance products and construction materials. Browse Cleaners, Lubes & Liquids for track cleaning and locomotive care, Hardware, and Layout Construction materials for building terrain, benchwork, and custom landforms.
