Signals are an important part of LEGO train layouts. The bring light and action to your layout and improves the fun factor and experience on the layout significantly.
Signals can be separated into two groups:
- Form signals (semaphores),
- light signals.
Additionally, signals can be grouped into:
- main signals and
Main signals must be obeyed in regards to their present aspect. A pre-signal indicates the status of the next main signal.
Designing fully functional, lighted and realistic form signals for the LEGO train system is a very challenging task.
Here is an example of a German semaphore (all designed by MattzoBricks):
This is an example of a German semaphore pre-signal, probably one of the most iconic form signals in the world (Design by MattzoBricks):
This is a German light signal with integrated pre-signal (H/V system):
Signals in MattzoBricks Train Automation System
The following diagram show the integration of signals into the overall MattzoBricks Train Automation System:
On our LEGO train layouts, all signals are automatically. How this is being done is shown in this video:
Our signals are controlled with a component called MattzoSignalController. Check this page to find out how to build such a controller yourself.
Instead of the MattzoSignalController, you may also use the more versatile MattzoLayoutController. The MattzoLayoutController can also be used to control semaphohres, as shown in the example below:
