Does the sign on the overhead wire indicate that you are approaching a junction with a change induced signalling device?
Show the correct answer
Correct answer
YES
Explanation
In the photo, we are driving a tram on segregated tracks next to the roadway, and a sign with the letter "W" hangs on the wire of the overhead contact line. The sign placed on the overhead wire means that you are approaching a junction with tram-triggered traffic lights (sygnalizacja wzbudzana) - the answer is YES.
At some junctions, the tram itself triggers a signal phase for itself - by passing under a contact on the overhead contact line or over a loop in the track. The "W" marking on the wire shows the place of such triggering, and the regulations on signs also provide for sign AT-2 "tram-triggered traffic lights", which warns of a junction where the tram triggers a separate phase for itself. The tram driver passes under the contact with the pantograph live (under voltage) and watches the traffic lights to check whether the phase has been triggered.
