“I want to start N scale model railroading, but I have no idea what to buy first…”
If this sounds like you, we recommend starting with a “Starter Set”—the perfect first step into the world of N scale. In this article, we’ll provide a thorough and easy-to-understand guide covering everything from the appeal of N scale to key points for choosing a set and specific product recommendations.

Let’s begin your journey into the deep and rewarding world of N scale!

What is N Scale? Its Appeal and the Role of Starter Sets

N scale is a model railway standard named after the letter “N” for Nine, referring to the 9mm gauge (the distance between the rails). In Japan, it is the most popular scale, boasting a massive variety of train models and related accessories.

Why N Scale?

  • Space-Efficient: Its compact size makes it perfect for Japanese homes. You can build a full-scale layout even in limited spaces.
  • Diverse Train Lineup: From Shinkansen (bullet trains) to local lines, commuter trains, steam locomotives (SL), and freight trains—almost every real-world train is modeled, making collecting a joy.
  • Realistic Dioramas: With a wide range of “structures” (buildings, stations, and scenery), the joy of creating your own miniature world is exceptional.

Starter Sets: The Beginner’s Best Friend

A Starter Set is an all-in-one package containing the three essentials: Trains, Tracks, and a Controller.
Buying a set is usually more affordable than purchasing items individually. It also eliminates the worry of compatibility, making it the perfect “passport” for beginners to enter the hobby with confidence.

The photo below shows the contents of a TOMIX Basic Set. In addition to Dr. Yellow, there is a wide variety of popular trains in the lineup. KATO’s starter sets follow essentially the same configuration.

Key Points for Choosing an N Scale Starter Set

To find the set that’s right for you, keep these key factors in mind:

1. Choose by Manufacturer (KATO vs. TOMIX)

The two giants of N scale are KATO and TOMIX. Both offer high-quality products, but they have distinct characteristics.

KATO (Sekisui Kinzoku Co., Ltd.)

  • Unitrack System: Features a durable, easy-to-connect integrated roadbed system. It ensures reliable electrical conductivity and stable running, making it very beginner-friendly.
  • Model Accuracy: Renowned for precise detailing and beautiful paintwork that faithfully captures the look of real trains.
  • Diversity: Boasts a wide range of models, including private railways, local lines, and even character-themed trains.
Recommended for

Those who want a stress-free setup and low-maintenance track system.

TOMIX (Tomytec Co., Ltd.)

  • Fine Track System: Offers a realistic appearance and a vast variety of track pieces. With many turnout (point) types, it allows for complex and flexible layouts.

  • System Expansion: Excellent automatic control systems (TCS), including working signals and level crossings.
Recommended for:

Those who want to pursue realistic scenery or challenge themselves with advanced layout control in the future.

2. Choose by the Included Train

The “face” of your set is the train. Choosing a model you love or have a personal connection to is the secret to enjoying the hobby long-term.

  • Popular Shinkansen: Icons like the E5 Hayabusa, N700S Nozomi, or the 923 “Dr. Yellow” are hits with all ages. Sets usually include a 3-4 car “Basic Set,” which can be expanded to a full 12 or 16-car consist later.

  • Commuter Trains: Familiar trains like the E235 Yamanote Line or E233 Keihin-Tohoku Line are popular for recreating everyday scenes.

  • Steam Locomotives (SL): For a touch of nostalgia, sets featuring the D51 or classic “Blue Train” sleeper cars offer a romantic, vintage atmosphere.

3. Track Layout and Controller Performance

Most sets come with a simple oval track. However, some premium sets include:

  • Sidings: To allow trains to pass or wait.
  • Viaducts: For elevated track sections.

Basic Oval Layout:

Most sets feature a simple circular or oval track plan designed for running trains in a continuous loop. Start by experiencing the joy of running your trains on this basic layout.

Sidings and Elevated Layouts:

Certain sets come with sidings for passing and overtaking maneuvers, or viaducts for elevated running. These sidings are typically composed of a combination of turnouts and straight rails.

If you want to start with a more elaborate layout right from the beginning, these advanced sets are a great choice. However, keep in mind that they tend to be a bit more expensive.

Controllers (Power Packs):

KATO Power Pack Standard SX

KATO starter sets come with the standard “Power Pack Standard SX.” It features a simple design that allows for intuitive operation. It provides a stable power output, giving beginners peace of mind. The unit also features terminals on the side for connecting turnout switches and other accessories.

TOMIX Power Unit N-600

The TOMIX Basic Set comes with the “N-600,” which is their most standard power unit. TOMIX also offers more advanced controllers, such as the “N-DU101-CL,” featuring a “Constant Lighting” (CL) function. This feature keeps the headlights and taillights illuminated even when the train is stopped, creating a more realistic atmosphere. It’s a great option if you decide to upgrade your controller in the future.

Finding the Right Balance for Your Budget:

Most starter sets are priced between 18,000 and 25,000 JPY. Keep in mind that prices go up for sets with iconic Shinkansen trains or high-tech controllers. You don’t have to buy everything at once; starting basic and expanding step-by-step is a perfectly good way to go. Consider your budget and your level of commitment when making your choice.

  3. Build a Diorama: Add stations, platforms, buildings, and tiny figures (people) to bring your layout to life.

N Scale FAQ for Beginners

Q: KATO or TOMIX, which is actually better?
A: There is no “best,” only what fits you. KATO is generally praised for track durability and ease of use. TOMIX is loved for its vast variety of track parts and realistic “Fine Track” appearance.

Q: How much space do I need?
A: A basic starter oval fits on a tatami mat (approx. 180cm x 90cm). A standard table or a dedicated 150cm x 80cm space is plenty for a start.

Q: Is it okay for children?
A: Most products are for ages 8 and up. Because they are precision models with small parts, we recommend parents help with the initial setup and teach kids to handle the speed controller gently.
