The signalling system is a crucial part of the SigLab, providing visual indicators for train movement control and safety.
Primary control signals
Three-aspect display (red, yellow, green)
Located at block boundaries
Controls train movement
Warning signals
Two-aspect display (yellow, green)
Located before main signals
Provides advance warning
Junction control signals
Multiple aspects
Located at switches
Controls route selection
Main signal body
Distant signal body
Route signal body
Mounting mechanism
