Last one. Line 64 existed until just a couple of years ago, with a very similar route.
This pic was tough to figure out where it was taken. Line 64 was very long, running from close to the harbour all the way up to Bonanova street on the foot of the hills. From the scenery it can't be too far up, because the buildings look different and sheit, and also note trolleybus wires, but for a large part of its route line 64 ran on two different streets in each direction. So it must be the lower part of the route where both directions ran on the same street. And indeed, I found the very buildings visible in the pic. You can see them here:
