into an unoccupied train at the terminal, with a preliminary report of 33 injuries from the impact. Plans for a new parking garage, which would bring 318 additional parking spaces to the station, were announced in October 2018. The garage would be located above the South Terminal bus berths, is expected to cost $37 million, and will break ground in summer 2020. A 2019 report suggested removing the bridge across Market Street in favor of a traffic-calmed intersection with crosswalks. Both measures would prepare the terminal for an increase in traffic following the proposed Norristown Line King of Prussia Spur. Market–Frankford Line platforms 69th Street is the Market–Frankford Line's western terminus. East of here, the route travels thorough West and Center City Philadelphia along Market Street, and then continues northeast to Frankford Transportation Center. The station is one of two ground-level stations of the Market––Frankford Line, and one of two SEPTA rapid transit stations outside the Philadelphia city limits. The station's three tracks and two platforms are located at the center of the terminal, sandwiched between the station building and the Norristown High Speed Line terminal. The northbound platform handles all alighting passengers while the southbound platform handles departing passengers. West of the station, a two-track balloon loop allows terminating trains to turn around and depart the station. There is also a large storage yard and a maintenance facility shared with the Media–Sharon Hill Line. Two MFL trains collided after one derails on the balloon track seriously injuring the operator. Norristown High Speed Line platforms SEPTA's Norristown High Speed Line (formerly Route 100) originates at 69th Street, continuing west and north to serve the communities of Haverford and Radnor before terminating at Norristown Transportation Center in Norristown. Unlike the Market–Frankford terminal, the Norristown Line tracks terminate at bumper blocks adjacent to the station, meaning that all platforms and tracks can handle both the boarding and alighting of passengers. Bus and trolley routes Surface transit lines at 69th Street are split into three distinct areas of the terminal. The largest of these areas is known as the West Terminal. It is located on a slightly elevated embankment west of the station house and adjacent to the intersection of Market Street and Victory Avenue. This area contains bus berths for routes , as well as two berths for the 101 and 102 trolleys. The two trolley routes run southwest out of the
