I sort of hope, although it's a longshot, that by installing these new trolley wires TL might get some experience with it and maybe will be more open to extending the trolley network... I think it remains a good investment.
For new routes, a few seem like low hanging fruit:
- Replicating the old 15 is obvious from 12th (soon) to marine stn, wires at both ends. Also, the 50, which has wires already throughout... these routes dont have as much ridership though.
-The 2 would be nice, also wires at both ends plus they'll be wiring MacDonald from 4th to Broadway. I don't know what the future holds for the 2 post-Broadway subway, but the demand for the northern part might even increase! This would be NIMBY central though.
- The 119 or 130 would be neat and achievable, and there are already wires to metrotown and kootenay loop, but it seems like in the past Burnaby hasn't been so keen. The 130 could link up with a 9 extension from boundary (wires could even run to BTC)...
(Longer term, if the north shore is keen (and they have their hills and busy routes), stanley park wires are just a bridge away. So is the 4 terminus, but we would have to have highway speed trolleys then)
