LEGO Train Automation

How to control four LEGO trains on one track.

The LEGO company offers remote controls to play with your trains. You can control up to four trains with one remote. This works fine as long as each train runs on a dedicated track and you only need to pay attention to one train at a time. LEGO only allows you to control trains. You cannot control track switches, lights or decouplers remotely.

The 4DBrix company is offering advanced train automation and today I would like to share my latest train automation project with you. I ran four trains on one track without any collisions.

This video shows all four trains from the top, including a picture in picture video of one of the trains.

This video is a 360 panoramic video. You can spin the camera and look at all the trains and LEGO sets.

I used 4DBrix’s nControl IDE to program all the trains that were connected to the computer using Bluetooth. nControl uses the Python programming language. One little hick up was the need to flash the firmware of my BLED112 Bluetooth dongle to allow for more than three trains simultaneously.
