I would call it Montco Lines - if only to pair it up with my preferred "Delco Lines" - which go to Delaware County, not Delaware State as "Delaware Lines" implies.These proposed changes are intended to help those who are unfamiliar with the system. Montgomery and Delaware introduce needless geo-political references; they would help no one, and savvy riders would just find them amusing. So, what to call the 69th Street operation? Red Arrow and Frontier won't pass muster; how about West Suburban Light-Rail. Give them letters perhaps, M-Media, S-Sharon Hill, N-Norristown. It makes a little more sense than San Francisco's N-Judah and J-Church. The SEPTA system is complex, that can't be fixed. A readily available hand-out paper map would help immensely.
