Thames & Kosmos TrainBots: 2-in-1 STEAM Maker Kit | Build Rolling Train & Walking Robot with LED Steam | Ages 8+

Choo choo! Thames & Kosmos TrainBots blends retro-futuristic charm with hands-on STEAM learning. This 2-in-1 kit invites young builders to explore motion, lighting, and steam-like effects as they assemble two distinct configurations in a single package.

Two designs, one kit

Switch between a rolling train and a walking robot by repositioning a few pieces. The quick-change design keeps play sessions fresh, rewarding curiosity with visible, tactile results and encouraging experimentation with different setups.

Live steam and glow

A LED lights the mist rising from the chimney while an ultrasonic atomizer turns tap water into a safe, cool fog. The combination of dynamic lighting and vapor adds drama to storytelling and pretend play, without creating mess or odours.

Inside the science pack

The kit features an electric motor, a circuit board, and an ultrasonic atomizer. Together they help illustrate basic principles of electricity, sound waves, and states of matter—concepts that show up in everyday tech without overwhelming beginners. The design invites discussions about the differences between fog, smoke, and steam, and how light interacts with mist to create atmosphere.

What you read and what you do

The 44-page full‑color manual includes a comic-book style story that brings TrainBots to life and guides builders through the setup step by step. The narrative adds play value by turning assembly into an adventure rather than a task.
