Downtown still has them. There are currently 13 routes and 262 buses, 74 of which are articulated.Vancouver, BC was full of electric busses but the city got rid of them and the overhead electric cables in time for Expo 86. They didn’t want the stodgey streetcar image.
They’re going to try out some overhead electric buses with smaller batteries so the batteries can charge while driving and the buses can go full electric for about 20km before needing to be connected again.
Apparently that extra bit of length on some of the electric routes will greatly increase the flexibility of the buses in terms of where they go, how many people they can serve, etc…
