The monorail opened two years after Toronto zoo opened and closed because there was a cash with two monorail trains that killing a few dozen passengers and if you don’t know what is a monorail it is a train that floats on tracks using electromagnets and they might build a another one that will go the same route as the other one and it promise the one the one that may be built will be safer and it will have new features like fail safe emergency braking and automated control and it won’t cost the zoo or the city a penny because the company will pay and the built one will open in 2022
