SEPTA would shutter the Cynwyd, Chestnut Hill West, Paoli/Thorndale, Trenton and Wilmington/Newark lines. Service across its five-county area would be cut by 45%, driving away customers and impacting fare revenues, Sauer said.

Thorndale line, Broad-Ridge Spur and dozens of bus routes could be on the chopping block if SEPTA can't get a funding boost.

All this can be avoided, the agency says, if Harrisburg can agree on a budget that funds mass transit statewide.
