Does the sign on the overhead wire indicate that you are approaching a junction with a change induced signalling device?

Explanation
Correct answer: Yes
The W-27 sign, marked with the letter 'W' and visible on the overhead line system, is an indicator for tram drivers. It informs the tram driver that they are approaching a junction with traffic lights which are activated (triggered) by an approaching rail vehicle.
