Although the Brown Line through Allentown is no longer in regular service, the Port Authority keeps it active for use as a detour when the Transit Tunnel under Mount Washington is closed. For several weeks in August of 2019, the tunnel was under construction, and all Red Line and Blue Line cars had to go over the Brown Line route. This is a simple record of what you see out the right-hand window on a car inbound from South Hills Junction to Steel Plaza. We go up Warrington Avenue and down Arlington Avenue, over the Panhandle Bridge, and into the subway.
