But a Trolleybus wouldn't solve any traffic problems, and wouldn't be
any faster than the buses there are now along Uxbridge Road - which I
thought was the main incentive for the tram. I use the route all the
time and traffic is really bad.In the end, trams are narrower than
buses so a right of way tramway would be easier to implement.

And I've been looking through those pictures and can't see any example
at all, of a trolleybus and its wiring that does not look ugly. I also
haven't seen much modern implementation of these things. If any at
all, really. Are there any cities that have recently constructed a
trolleybus network? The only example I can find is the Silver Line in
Boston, which all Bostonians I've talked with seem to hate.

Every now and then I seem to run into a few enthousiasts about the
whole thing, but I haven't seen any serious planning for a system.
Wikipedia doesn't help much, either.

And I still think they're just very ugly. Pollution is a problem
obviously, but I hope we can find a nicer way around it than this.
