- Why did the trolley buses disappear from Toronto's streets?
Bad timing, mostly. Electric vehicles have longer lifespans than their diesel counterparts (at least 30 years versus 12-18 for the average bus), but even these vehicles have to be rebuilt or replaced sometime. The most recent fleet of Toronto's trolley coaches started operating in the year 1947. In the late 1960s, the TTC had the entire fleet rebuilt by Western Flyer, and that added another twenty or so years to the trolley buses' lifespan. That brought the fleet to 1992.
By 1992, the fleet was showing its age again, and the infrastructure was also on its last legs. To retain trolley coach service, the TTC was looking at either rebuilding or replacing its fleet, and spending millions to upgrade aging infrastructure. The price of oil was also very low at this time, and the electric trolley buses had become the most expensive surface vehicles of the fleet to operate. Add to this a budget crunch and shrinking ridership from the recession, and the TTC decided that the trolley buses weren't worth it, anymore.
The final straw was the natural gas buses. At the time, this new technology promised quiet, smooth operation and reduced pollution, and the builders marketed these buses as ideal replacements for trolley bus service. The TTC did not stop to think that these improvements only appeared when natural gas buses replaced diesels; instead, it pushed for a change of technology from electric trolleys to natural gas. The natural gas design has shown its flaws, since then, and the TTC are no longer as interested in the technology.
In general, trolley buses were the poor siblings of transit agencies' streetcar and bus fleets. While theoreticially combining the advantages of streetcars and diesel buses (lower emissions, greater flexibility, less likely to be blocked by traffic), practically they also combined the disadvantages of both technologies (less capacity, more infrastructure required). In Toronto, the trolley buses were usually assigned to lower-demand residential ex-streetcar routes. Except for Bay and Ossington, they were never assigned to transit corridors where frequent service was required. Their adept handling of steep hills was never displayed in flat Toronto. In general, they were never given a chance to prove themselves.
- Why do trolley buses use two trolley poles and streetcars only use one?
Electrons are charged particles and are repelled from negatively charged surfaces and are attracted to positively charged surfaces. For electrical components to work, they must stand between this flow from negative to positive. If anything prevents electrons from running to the positive surface (e.g. the positive outlet of a battery or plug) from the negative surface (e.g. the ground or the negative outlet of the battery or plug), then there is no current, and electrical motors won't operate.
Streetcars take power from a charged trolley wire. The electricity travels through the trolley pole and the inner workings of the streetcar and is channelled out of the wheels and into the rails and the ground. Trolley buses have rubber-tired wheels, however, and rubber is an effective insulator against electrical current. To have a current, the trolley bus must either string a metal chain from the motor to the ground, or return the power to a differently charged wire. Guess which is safer and more practical.
There are streetcars which operate using two trolley poles. Cleveland is one example. This is done when the transit agency wants a more controlled circuit, rather than routing the electricity into the ground via the rails.
- Why were there two separate divisions of trolley bus routes in Toronto?
Eglinton Division and Lansdowne Division remained separate because the route that was to connect them together was never converted to trolley bus operation. The TTC had serious plans to convert the 32 Eglinton West bus to trolley coach operation (going as far as to construct a rollsign for it), but never followed through. Possibly this was due to opposition by Forest Hill residents to the stringing of overhead wires along Eglinton Avenue.
- So, how did trolley buses get transferred from one division to the other?
They were towed.
Seriously, that's probably how the TTC did it. Fortunately, they didn't have to do this very often, as both the Eglinton and Lansdowne Garages had the facilities necessary to perform all of the necessary maintenance. Without the trolley wires, there was no other option in moving the trolley bus around. Well, you could try batteries, but batteries are the reason why Toronto's Last Trolley Bus rots in a parking lot instead of runs on city streets.
