The Scarborough line opened in March 1985 as the Scarborough RT. Three years after it opened, the TTC renovated its southwestern terminus at Kennedy station, because the looped turnaround track, designed for uni-directional streetcars under the earlier plan and not needed for the bi-directional ICTS trains, was causing derailments; it was replaced with a single terminal track and the station was thus quasi-Spanish solution, with one side for boarding and another side for alighting, though the boarding side is also used for alighting during off-peak hours and weekends.
