10 Best Toy Train Sets 2026 in the United States

The LEGO Super Mario The Bowser Express Train set is designed for kids aged 9 and up, making it suitable for older children who enjoy construction and imaginative role play. Unlike traditional toy trains that run on fixed tracks, this set focuses on a buildable train with interactive play features rather than powered movement, as it does not include a motor or battery-powered engine. The train measures about 26.5 inches long, which is a good size for tabletop play and fits well with other LEGO Super Mario sets. Made from durable LEGO plastic, it promises long-lasting use and easy assembly with 1,392 pieces.

The set stands out for its rich details, including a locomotive with a spinning platform, a removable roof on the passenger wagon, and a spring-loaded cannon wagon. It includes six Super Mario-themed minifigures like Hammer Bro and Boom Boom, which add to the storytelling and play value. While it doesn't run on traditional train tracks, the set includes two stations and a handcar to expand gameplay.

A unique strength is the companion LEGO Super Mario app, offering digital building instructions, tips, and interactive challenges that blend physical and digital play—perfect for kids who enjoy technology-enhanced experiences. LEGO Mario figures required for full interactive play are sold separately, which is important to consider. This set suits children who enjoy creative building and interactive Super Mario adventures rather than those looking for a classic motorized train set. Its sturdy construction, detailed design, and app integration provide a fun, imaginative experience, although the absence of a powered engine and the need for additional figures might limit its appeal for some.

The Thomas & Friends Multi-Level Toy Track Set is designed for preschool kids aged 3 years and older, making it age-appropriate for young children. It features a multi-level track layout standing over 2.5 feet tall, incorporating favorite characters and locations from the show such as Tidmouth Sheds, Brendam Docks, and several cranes. This makes the set engaging for kids who are fans of Thomas & Friends, adding to the imaginative play experience.

The track is compatible with other Thomas & Friends tracks (excluding wooden tracks), allowing for expansion, but additional tracks must be purchased separately. It comes with a motorized Thomas engine, a die-cast Percy engine, Harold the helicopter, and cargo crates, providing a good variety of accessories for interactive play. The power source for the motorized engine requires 2 AAA batteries, which are not included, so parents should be prepared to purchase these.

The set is made by Fisher-Price, known for durable toys. The large dimensions of the set (25.59 x 32.28 x 34.25 inches) require considerable space for setup and storage. The product's weight of 5.38 pounds makes it manageable but still requires some adult assistance for younger children. This toy train set is well-suited for young Thomas & Friends enthusiasts, offering engaging features and durable construction, though it does require additional space and battery purchases.

The BRIO World 33052 Deluxe Railway Set is a comprehensive and eco-friendly wooden train set suitable for children aged 3 and up. This set stands out for its detailed and varied components, including passenger and freight trains, harbor and metro scenes, stations, cranes, bridges, and figures, making it highly engaging for imaginative play. It is also a great tool for developing cognitive and motor skills in children.

The set's compatibility with other BRIO railway toys allows for expandable fun as your child grows, and the inclusion of batteries ensures immediate playtime readiness. The material is durable and FSC certified, ensuring it's safe and eco-friendly, which is a significant plus for environmentally-conscious parents.

However, some potential drawbacks include its relatively high weight of 11.83 pounds, which might be cumbersome for younger children to move around. Additionally, while the set is expansive, it may require quite a bit of space due to its large dimensions. Despite these minor issues, the set is highly rated by users, with a 4.6 out of 5 stars average from 1,275 customer reviews, indicating a strong satisfaction level among buyers. This train set is ideal for parents seeking a robust, engaging, and sustainable toy for their children that also promotes skill development.
