The Greater Cleveland Regional Transit Authority numbers them as Route 67 (Blue) and Route 67A (Green). The lines are also referred to by their former names; the respective boulevards that they travel on: the Van Aken Line (Blue) and the Shaker Line (Green). The system dates to 1913, making it one of the few surviving American "light rail" systems of the original streetcar era during the late 19th and early 20th centuries.Route descriptionWaterfront LineThe first 2.2mi of both lines is designated the Waterfront Line as it travels near the shoreline of Lake Erie and the east bank of the Cuyahoga River.
