>>1018040The Red Arrow Lines was one of two interurban lines to escape abandonment, operating until 1970 before it was absorbed into SEPTA. Like the North Shore Line, it was notable for high-speed service (I believe the Brill "Bullets" could hit 90mph) and blurred the line between "interurban" and "rapid-transit".
They also considered acquiring the 450-series cars (seen at 0:00, 1:40 and 2:04 in this video
>>1018018) from the then-mothballed CA&E before choosing the Electroliners instead. I have been told this was largely due to the fact that the Electroliners had a bar and grill built-in.
