For trolley geeks, here is a 4100 series Siemens car picking up passengers at the Hampshire stop on Route 42 in Beechview in 2001. This is the livery these cars were originally issued when they were put in service in the middle 1980s. Route 42 is now the Red Line, and the 4100 series cars were rebuilt as the 4200 series, with a new livery to match the newer CAF cars.
