Looks like a signal to me...

Wondering why this family shows up as a controller....

Hi Trevor,

in the past, MBS did not support signals with more than 2 states, why some content creators built multi-state signals with the help of a controller.

Kind regards,

I believe that since this is a foresignal (Vorsignal) and can control the state of the actual signal, that is why it would be a controller rather than just a signal.
