The Thornton Tunnel is a freight railway tunnel in Burnaby, British Columbia, running under the Willingdon Heights and Vancouver Heights neighbourhoods.[1] It was built in 1969 by Canadian National to connect Second Narrows Bridge[2] to the main line in Willingdon,[3] and is 3.4 km long.
In the middle of the tunnel there is a fake house to cover up a ventilation shaft and fan systems to blend in a residential neighbourhood. It is located on the northeast corner of Frances Street and Ingleton Avenue, in Burnaby.[4] [5]
