10 January 2020 / #history #transit TWEETED: What year is this OC Transpo system map from?#throwbackthursdayOC Transpo tweeted this on Thursday with a question: “Can you guess the year of the system map seen here?”A couple of people were pretty close, with some guesses for the 1960s or late ’50s. Kudos to Andrée LaFontaine who correctly guessed 1954 or 1955. (It was ‘54!)
