Tioga is part of the Frankford Elevated section of the line, which began service on November 5, 1922.

Between 1988 and 2003, SEPTA undertook a $493.3 million reconstruction of the 5.5-mile (8.9 km) Frankford Elevated.
Most of Tioga station was completely rebuilt on the site of the original station, though the eastbound platform exit uses an component of the original station.
The reconstruction project included new platforms, elevators, windscreens, and overpasses, and the station now meets ADA accessibility requirements.
The line had originally been built with track ballast and was replaced with precast sections of deck, allowing the station (and the entire line) to remain open throughout the project.

During the Market–Frankford's rush-hour skip-stop service pattern, Tioga was only served by "A" trains.
This practice was discontinued on February 24, 2020.
