I noticed that in the ps4 version when you enter the tunnel that goes under the city, the pantograph stays the same way as it was outside tresspasing the tunnel cable. It really looks kind of weird so if you have the same problem please write about it so Dovetail Games hears about it. I´m not quite sure if this happens in the other versions of the game or just in the ps4 so if you have the game for pc or Xbox please try and take a look and see if it happens there too.
Known issue since allmost a year now, reported many times to DTG and ignored. It's the same on the PC version.
