Pay As You Enter. Built in 1915, a predecessor of the streetcar, it has a rear entrance marked "Pay As You Enter." The idea of having the conductor stationed in one spot instead of following a passenger to his seat to collect the fare was considered revolutionary at the time. This is the only one of the series that is in its original form as the others were scrapped or converted to other uses after 1926. Restored by the Halton Region Radial Railway Museum.
