We have specifically looked into the recent on-time performance of Train 4756 and have concluded that it is often affected by issues on the Airport Line where your Chestnut Hill East train trip actually begins. Related link: Ask SEPTA: Fixing the El tracks One such issue identified is how we cross-route trains, particularly those going to and from the Airport. We are are working hard to understand all of the causes for this trend and how they interact with each other. Recently, performance on our Regional Rail lines has been below acceptable benchmarks. SEPTA monitors the on-time performance of all of trains, buses, trolleys and subways to make sure they meet our standards. Jeff Knueppel : I’ve been riding the Lansdale Line since around 1996 and as a regular rider I know how frustrating unreliable service can be. Question 1: Train #4756 from Jefferson Station at 5:13 to CHE has been consistently late (20 minutes or more) for the months of July and August. These are exciting times for Septa and I look forward to connecting with you and receiving your feedback through this column. By focusing on the fundamentals - customer satisfaction, safety, investment in our infrastructure and vehicles, and business innovation, we will be working to build a stronger SEPTA that will benefit our entire region. SEPTA’s emphasis on the customer, started by previous GM Joe Casey, will continue as our team moves forward.
