Toronto's modern subway trains represent a significant evolution from the trains that first carried passengers on the city's rapid transit network in the 1950s. But while the TTC's original subway trains have long since been retired, there's still one place you can experience what it was like to ride them. The G series trains were gradually displaced by M series trains starting in 1962 and H series trains in 1965, before the final trains were eventually pulled from service in 1990. But perhaps the standout attraction stored in the museum's main vehicle barn is the preserved G series train. Now, three-quarters of a century later, and with G series trains off TTC rails for 35 years, the preserved train cars in Milton keep this excitement alive and well.
