What does the train number 702 signify?

The significance of train number 702 being associated with the Chestnut Hill East and Trenton Lines is based on SEPTA's system of numbering that generally categorizes services by line. In SEPTA's operations, specific numbers are linked with particular lines to facilitate identification and scheduling for both operators and passengers.

Train numbers typically have a structured system where certain ranges are assigned to specific lines. Train 702 falls under the range designated for services that operate on the Chestnut Hill East and Trenton Lines. This helps crew members and passengers quickly recognize which line a train services. For individuals using the transit system, understanding this numbering is essential for navigating routes effectively.
