Subway surface trolley lines in Philadelphia 2020

Tram/trolley/subway thingy in Philadelphia, USA - The SEPTA subway–surface trolley lines are a collection of five SEPTA trolley lines that operate on street-level tracks in West Philadelphia and Delaware County, Pennsylvania, and also underneath Market Street in Philadelphia's Center City. The lines, Routes 10, 11, 13, 34, and 36, collectively operate on about 39.6 miles (63.7 km) of route. SEPTA's Route 15, the Girard Avenue Line, is another streetcar line that is designated green on route maps but is not part of the subway–surface system. Like Boston's Green Line and San Francisco's Muni Metro, the SEPTA trolley line is the descendant of a pre-World War II streetcar system. Where Boston and San Francisco's systems use longer, articulated LRT vehicles, Philadelphia uses rigid vehicles roughly four feet longer than the PCC streetcar they replaced. The lines use Kawasaki Type K LRVs delivered in 1981-82. The cars are similar to those on Routes 101 and 102 100 series, SEPTA's suburban trolley routes, which were delivered around the same time. However, the subway–surface cars are single-ended and use trolley poles, while the suburban lines use double ended cars and pantographs for power collection ~Wikipedia - Comment below so we can all have a productive 'conversation about transportation!'
