The roundhouse was designated a National Historic Site of Canada in 1990.
The 120-foot turntable in the center of the park is original to the 1929 facility.
The park contains the last remaining bay-and-gable style station building, moved from its original location to be preserved.
The miniature railway tracks cover a portion of the original freight yard site.
Three separate historic locomotive types are displayed, including a diesel-electric switcher and a steam engine.
Roundhouse Park is a 17-acre public park built around the historic John Street Roundhouse, a restored 1929 locomotive repair facility. The park serves as the home for the Toronto Railway Museum and houses a collection of preserved historic railway equipment, including steam locomotives and passenger cars. Visitors can ride the miniature steam train that traverses a loop through the park grounds. The site features the original 32-stall roundhouse building and a functioning turntable once used to rotate trains. Historic signals, switches, and a water tower are integrated into the landscaping. The park preserves the industrial heritage of the former Canadian Pacific Railway yard. It is surrounded by modern downtown development, contrasting historic rail infrastructure with contemporary architecture. Pedestrian pathways offer views of the restored bay-and-gable station building.
The elevated viewing platform overlooking the central turntable provides the best angle of the roundhouse and stationary locomotives.
Check the miniature train schedule in advance as it operates on a seasonal, weather-dependent basis.
Walk the full perimeter of the turntable to see the historical mechanical components of the switching system.
Combine your visit with the indoor exhibits at the Toronto Railway Museum located within the roundhouse.
Do not attempt to climb on the static train equipment displayed on the outdoor tracks for safety reasons.
The miniature train and outdoor exhibits are seasonal, typically operating only from spring through autumn.
