How to Make a Trackless Train: Step-by-Step Guide for Builders and Operators

Trackless trains are popular amusement rides in theme parks, zoos, shopping centers, and scenic areas. If you want to learn how to make or build a trackless train from scratch, this guide will walk you through the entire process from design to final deployment.

Whether you are a ride manufacturer, investor, or operator, SUNHONG engineers will help you understand how professional trackless train producers build trackless trains, including the construction process, key materials, power systems, and safety testing.

How to Build a Trackless Train？

1. Design the Trackless Train

First, define your overall concept:

• Theme and appearance: Classic steam locomotive, animal appearance, ocean theme, jungle theme, or customized IP design.

• Passenger capacity: Understand your target visitors and choose the number of carriages based on space and usage scenario. Seating capacity ranges from 22 to 60 people.

• Functions: LED lighting, music system, smoke effects, voice narration, AI navigation system, etc.

• 4D Spinning Coaster

After confirming the required features of your trackless train, provide your needs to a customization factory. SUNHONG can offer a one-stop park operation guidance service. You can provide SUNHONG's design engineers with your park's customization, visitor age and volume, and local aesthetic preferences so that they can design or recommend the most suitable trackless train for your needs.

2. Collect Materials and Key Components

To build a trackless train, you need:

• Chassis materials: Steel or aluminum (Q235 steel is recommended due to its strength and safety)

• Passenger capacity: Understand your target visitors and choose the number of carriages based on space and usage scenario. Seating capacity ranges from 22 to 60 people.

• Body materials: Fiberglass Reinforced Plastic (FRP), which is widely used on trackless trains for its corrosion resistance and lightweight properties

• Power system: Commonly used cost-effective lithium iron phosphate or lead-acid batteries. Diesel engines are also an option, with the benefit of not worrying about battery range.

• Control system: Steering wheel, brake system, power system, dashboard, and AI obstacle avoidance system

• Carriages and couplers: Flexible joints, usually made of 316L stainless steel

• Decorations: Lighting, seat decorations, and IP character figures

3. Build the Chassis and Frame

The chassis is the foundation of the train and must be strong, safe, and able to bear weight.

• Use Q235 steel or aluminum alloy for the frame

• Adopt professional welding or bolted connection techniques to link the transmission system, suspension, and wheel mounting points

4. Assemble the Locomotive and Carriages

• Mold the locomotive head using fiberglass materials based on the theme or IP design

• Assemble canopies or roofs to protect passengers, and consider installing sunshades depending on the region

• Decide whether to install doors, also molded from fiberglass

• Add internal seats, seat belts, handrails, and non-slip flooring

5. Install the Systems

According to electric or diesel systems, install:

• Steering system and brake system

• Dashboard controller (used to control power, horn, lights, music, smoke, etc.)

6. Install Suspension, Tires, and Couplers

• Add shock absorbers to improve comfort

• According to the actual need, install 600-13 or 600-19 vacuum tires

• Use heavy-duty tendons to ensure safety and stability when turning

SUNHONG trackless trains use high-quality wheels and suspension, which greatly improve ride safety and driving stability.

7. Paint and Decorate the Train

• Use automotive-grade paint, which is durable and has good color retention

• Install lighting systems, audio systems, IP configurations, and characters

• Choose suitable decorations according to the theme to enhance visual appeal and immersion

8. Testing and Quality Control

Before launch:

• Test systems: braking, steering, suspension mechanics

• Test electrical systems: lights, music, battery performance

• Check safety systems: seat belts, emergency stop device, load-bearing capacity

Ensure the equipment testing complies with international safety standards such as CE, ASTM, or EN13814.

9. Final Adjustment and Launch

Make the final adjustments and touch-ups.

• Ensure your train

• Drives smoothly 

Then, you can launch your brand-new trackless train journey!

How Does a Trackless Train Operate?

Unlike traditional trains, trackless trains run on regular roads or smooth paths without tracks. They work as follows:

• Power source: Electric or diesel engine powers the locomotive

• Steering: Controlled by the vehicle using the road surface and the pedal

• Couplers: Flexible hoses connect each carriage, allowing easy turning

• Braking: Hydraulic or disc brakes ensure safety

• Passenger area: Comfortable seats, seat belts, lighting, and music create an immersive experience

Conclusion

Building a trackless train takes time, engineering, and creativity. From material selection to system installation and final decoration, every step matters. If you're considering building one for your park, mall, or tourist site, SUNHONG provides custom design, manufacturing, and installation services to support your full project.
