Your post got me looking at http://septa.org/service/interruption/2016-guide.html" onclick="window.open(this.href);return false; again.
All regular fares will apply. Passes offer the best value for your money and will make traveling easier. In the event of a service interruption, Weekly and Monthly TransPasses, including SEPTA Key Cards with current Pass product, will be valid, for travel, at all times, to all Regional Rail stations within the City of Philadelphia except Forest Hills and Somerton. These stations will require a Zone 3 fare - ticket or PassI thought the last time this happened, all passes (trail/trans, all zones) were good on all of the RR. Is there confidence that Suburban and Victory will definitely not join City division?
