The Blue Line shares the right-of-way with the Green Line in Cleveland, and splits off after passing through Shaker Square. All RTA light rail lines use overhead lines and pantographs to draw power. Interurban portion From Tower City to just east of East 55th Street, the Blue and Green Lines share track with the Red Line for 2.6 miles (4.2 km) along a private right-of-way originally acquired in 1930 to bring intercity trains into Cleveland Union Terminal (the site of today's Tower City Center). The Tri-C–Campus District station and the East 55th station are shared by the heavy rail rapid transit Red Line and the light rail Blue and Green Lines on the same platform, an arrangement unique in North American rail transit. The shared stations have low platforms for the Blue and Green Lines directly adjacent to high platforms for the Red Line. RTA Central Rail yards and headquarters are located at the East 55th station, where trains of all rail lines are stored and serviced. East of East 55th, the Blue and Green Lines split from the Red Line and travel east on a separate, dedicated, grade-separated right-of-way. A complex of tunnels existed at this junction to provide means for the Blue and Green Line trains to switch from right to left side running from East 55th to Tower City, but right side running is now used throughout the system, and the tunnels have been closed. The private right of way extends from this junction to Woodhill Road at the western end of Shaker Boulevard and then below grade through an excavated cut in the median of Shaker Boulevard to Shaker Square. Along this portion of the lines are East 79th station, Woodhill station and East 116th Station. The lines then rise to street level at Shaker Square.
