One of the most popular evergreen toys is also one of the simplest, wooden track with push-along trains. We all know the brand name, and savvy parents know to pick up the much cheaper knock-off because the kid won’t know the difference. But a really cool kid shouldn’t have to push their train around by hand, and thus [Lauri] has given the wooden track a real, powered, locomotive.
In the 3D printed chassis goes a small geared motor driving one axle, with an ESP32 and a motor driver taking care of the smarts. Power comes from an 18650 cell, which almost looks like the right scale for a fake steam boiler. The surprise with this train comes in the front axle, this machine has steering. We’re curious, because isn’t the whole point of a train that the track directs it where it needs to go? Or perhaps a little help is required in the absence of a child’s guidance when it comes to points. Either way, with remote control we guess there would be few kids who wouldn’t want one. We certainly do.
