How it works
An easy way to automate your LEGO trains (or compatible) is to use an SBrick.
An SBrick is a small bluetooth device that is mounted between your battery box and the train motor as shown on the following picture.
No soldering and tinkering is required – just connect the plugs like you would do it when building a standard LEGO train set.
You can also connect two or more motors to the SBrick, and add Power Functions lights!
How to connect the solution to the Mattzobricks Train Automation System 2.0 is described on the MTC4BT page.
SBrick informed us that they are not able to produce new SBricks. So, if you own an SBrick, or are able to buy a used one, you can call yourself lucky.
