Wattman builds two trackless train models for the US market: the Mini Express and the Maxi Express. Both are independently certified, ASTM-compliant, and eligible for the Assured Value Program. Both are custom-built to operator specifications.
The question is not which one is better. It is which one is right for your venue, your guest volume, and your operational requirements. This mini express vs maxi express comparison provides the framework.
Core Differences
The fundamental difference is scale. The Mini Express is a compact-format train designed for venues where space, maneuverability, or portability are primary considerations. The Maxi Express is a high-capacity train designed for venues that need maximum throughput and sustained daily operation.

| Passenger capacity | Compact guest load | 30+ passengers |
| Battery runtime | Full-day operation | 8+ hours per charge |

Venue Fit Guide
The right model depends on the venue.
Customization and Editions
Both models are available in multiple Edition levels (Essential, Classic, Signature) and are fully customizable. Colors, branding, seating configuration, lighting, audio, weather covers, and ADA accessibility are specified during the order process.
The production timeline is 5 to 6 weeks from order confirmation for both models. Every unit is built to the operator's exact specification.
The AV Program on Both Models
Both the Mini Express and Maxi Express are eligible for the Assured Value Program. The coverage is identical: 48 months of full-train warranty, guaranteed trade-in value, and financing access.
The trade-in guarantee structure is the same for both: 35% at month 36 through 48, 25% at month 49 through 60. Operators who start with a Mini Express can apply their trade-in credit toward a Maxi Express when they upgrade.
Starting Point vs. Growth Path
For operators entering the trackless train business, the Mini Express is often the starting point. Lower initial investment, broader venue flexibility, and the portability to serve multiple event types from a single trailer.
For venues with established high traffic, the Maxi Express is the right choice from day one. The capacity and throughput are designed for the demands of daily operation at scale.
The AV Program connects both. Cesar Aguilar of Kiddos ChuChu expanded from a Mini Express to both a Mini and a Maxi. Joe Rios of Li'l Grande Trains grew from one Mini Express to three trains. The 4-year cycle creates a predictable growth path.
The growth equation: Start with a Mini Express. Prove the revenue. Apply the 35% trade-in credit at month 48 toward a Maxi Express or a new Mini Express. Start a fresh AV Program cycle. Repeat. The operator who plans ahead can scale predictably.
Same Standard. Your Choice.
Both trains are built to the same standard. Both include the same AV Program. The choice comes down to your venue's requirements today and your growth plan for the next four years.
