 Both the light rail and the heavy rail subway cars share the station.East 34th and East 55th are the only stations on the Blue/Green Line, other than downtown's Tower City station, to utilize an island platform.Therefore, due to the fare collection procedure used on the Blue/Green Line, disembarking Blue/Green Line westbound passengers must walk to the front of the train and pay their fare or swipe/dip their farecard at the farebox before walking back through the train to exit one of the car's side left doors.
