10 Best Toy Train Sets 2026 in the United States

The LEGO City Explorers' Arctic Polar Express Train Set is a fun and engaging toy designed for children aged 7 and up. Its remote-controlled motorized train and detailed Arctic-themed accessories like a snowplow locomotive, research station, and explorer minifigures create an immersive play experience that encourages creativity and imaginative storytelling. The train measures about 27.5 inches long, which is a good size for play without being too bulky. It uses 6 AAA batteries and can be controlled with a remote or a smart device app, adding interactive options that kids will enjoy.

The set includes fun features like a mountain tunnel with a rockfall effect and a zip line, making the play more dynamic. Made from durable LEGO bricks, the train and accessories can withstand regular play and also connect with other LEGO City sets for expanded adventures. The requirement for multiple batteries may add to ongoing costs, and the set’s complexity with over 1,500 pieces might be challenging for younger or less experienced builders.

Additionally, there is no traditional train track included, so the set focuses more on imaginative play than realistic train layouts. This makes it best suited for kids who enjoy building detailed models and interactive play rather than those looking for a classic track-based train experience.

The KidKraft Waterfall Mountain Wooden Train Set & Table is well suited for young children aged 3 and up, making it a great choice for toddlers and preschoolers starting to explore train sets. It features a large wooden table with a colorful mountain village design, providing plenty of space and multiple play areas like a helicopter pad, suspension bridge, and waterfall tunnel. With 120 pieces, including tracks, buildings, trees, and signs, kids can create different layouts, encouraging creativity and extended playtime.

The trains connect magnetically, which is easy and safe for little hands, and the set includes a working wooden crane that adds interactive fun. Made from premium sustainable wood, the set is durable and eco-friendly, able to withstand regular play. The table's three built-in storage bins allow for quick cleanup, helping keep play areas tidy. However, the train set is manually powered, so it lacks motors or batteries, which might limit appeal for kids who prefer electronic trains.

Also, while compatible with other major wooden train brands, the large size and weight of the table (almost 47 pounds) means it requires a dedicated space and may be less portable or suitable for smaller rooms. This train set delivers a rich, hands-on experience with quality materials and thoughtful features that suit young children and encourage imaginative play, though it may not meet the needs of older kids looking for motorized or more complex train systems.

The Lionel Disney Christmas LionChief 0-8-0 Set is a vibrant and festive choice for kids aged 8 and up who enjoy classic O Gauge model trains mixed with Disney magic. It comes with a well-sized 45-inch track layout featuring Lionel's FasTrack system, which is known for its easy snap-together pieces that provide a stable and reliable track connection. Its O Gauge scale (about 1:48) is a popular, traditional size, making this set suitable for collectors and enthusiasts as well as younger users.

The electric train runs on a maintenance-free motor and is powered by 3 AAA batteries for the remote, which is user-friendly and supports Bluetooth operation via a smartphone app and even voice commands, adding a modern twist to classic train play. The set also includes charming features like puffing smoke, authentic steam sounds, a whistle, bell, and fun Mickey Mouse announcements, enhancing the immersive experience. The plastic and metal parts appear sturdy enough for regular play, although some care like lubrication and gentle cleaning is needed to keep it running smoothly.

One downside is that the remote requires batteries (not included), and some assembly tools like a Phillips screwdriver are needed. The larger size and complexity may be less suitable for very young children or those new to model trains. This train set blends traditional track and scale quality with engaging Disney-themed details and advanced remote controls, making it a great pick for kids and collectors looking for a holiday-themed, interactive electric train experience.
