I like the old fashioned slot boxes. They are a simple, effective method. Not dependent on computers or the internet or electronics.
"[W]e are temporarily capping the number of new Key Cards available for Regional Rail at 2000."
[...]
As with Transit, we will take a few months to evaluate how SEPTA Key is working on Regional Rail to determine if there are adjustments that need to be made for our customers and train crews before we resume the sale of new Key Cards for TrailPass purchases.
While no new Key Cards are available for sale at the Center City Regional Rail Stations we want to encourage our Early Adopter customers to continue to reload their Weekly and Monthly Zone 3 or 4 TrailPasses online at septakey.org or at one of the Center City Regional Rail Sales Offices. Early Adopters with valid Zone 3 & 4 TrailPasses loaded on a Key Card will continue to present their Card to the Conductor for validation, upon request.
Legacy TrailPasses for all Zones will continue to be sold at outlying Ticket Offices and at the Temple, Jefferson, Suburban, 30th St., and University City Regional Rail Station Ticket Office.
