The Scarborough Rapid Transit line was approved by the TTC in January 1977 to meet the considerable population growth anticipated in Scarborough. After Kennedy Station, there would be stations at Lawrence, Ellesmere, Midland, the Scarborough Town Centre, and McCowan. The line would run entirely on its own right of way, separated from street traffic, and for part of the way would be elevated above ground. While the original plan called for light rail cars to be used on this route, the Province’s Urban Transportation Development Corporation suggested that its new Intermediate Capacity Transit System (ICTS) be used, and the plans were changed from light rail to the new system after construction had already commenced. The ICTS cars used a new method of power and propulsion, and was the first instance in North America of a computer-controlled automatic train operation.
In 1982, believing that the new technology required it to be identified as something other than a subway, the TTC held a naming contest for the new line. The winning suggestion, out of 5600 entries, was the Scarborough RT, submitted by Alvin Frost. In 2014 the line was renamed Line 3 Scarborough, as part of the new line numbering for all four TTC rapid transit lines. Use of the “Scarborough RT” name, and the “SRT” abbreviation, remain common.

View looking east through Kennedy Station showing paver tiles installed on south platform. The top level of Kennedy Station had been built for light rail trains. It was altered for the new ICTS trains, which required higher platforms. Raising the platforms also required the roof to be raised, to provide enough clearance for customers on the platforms.
