October 31 is the last day the Caltrain mobile app can be used to pay for train fares and parking at Caltrain stations. After that date, the app will no longer operate because the contract between Caltrain and the app provider will expire and not be renewed for several reasons.
One major reason for the non-renewal is that, as part of an agreement with MTC to support Clipper 2.0, individual transit agencies must discontinue separate ticketing apps that compete with Clipper. The new version of Clipper will offer features such as tap-and-ride with contactless debit and credit cards, recently implemented by BART, as well as transfer discounts between transit agencies. However, the Clipper 2.0 project has been delayed overall.
Even with Clipper 2.0, some features of the old app will not be replicated, such as the ability to purchase tickets for groups—including families—especially those eligible for discount categories like youth, seniors, and people with disabilities. Riders in these categories must apply for a personalized discounted Clipper card to receive discounts on Clipper; otherwise, discounts will not apply, though they can still board buses or Caltrain and pay discounted fares. Without the app or Clipper, these riders can purchase discounted paper tickets from ticket vending machines at stations.
The app has also been used for parking payments at Caltrain stations. Starting in November, parking payments at Caltrain stations can be made with the ParkMobile App or by paying at a ticket vending machine.
