The TTC promises the brand new fleet of streetcars it bought will be good for commuters in Toronto; even those who travel by car.
Officials with the Transit Commission say the new vehicles are faster than the 30-year old models they will replace and will not need to stop as long to pick up and drop off passengers.
However, traffic flow at certain intersections across the city could be where things get bogged down.
The new Bombardier-built streetcars are almost twice as long as the TTC's current standard-length unit.
That means it will take longer for the articulated streetcars to negotiate corners.
Veteran TTC driver Doug Pickering tells NEWSTALK 1010 that could spell headaches at intersections where streetcars must turn.
"Unfortunately, because of the position we're in, we're going to have to bully our way through (an intersection) a lot of times," he says.
"We are going to be blocking other traffic - there's no other way around it."
Pickering believes it'll take people behind the wheel of cars and trucks time to adjust to sharing the road with the new vehicles.
TTC CEO Andy Byford is confident the new streetcars will actually improve the efficiency of downtown traffic flow.
He promises TTC drivers will be trained to share the road and to keep delays to an absolute minimum.
The new vehicle start going into service in late August and will be phased in over the next 4 years.
