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

[1][4][5][6] Between 1988 and 2003, SEPTA undertook a $493.3 million reconstruction of the 5.5-mile (8.9 km) Frankford Elevated.

[7] In 2019, the Philadelphia Weekly magazine called the intersection "one of the most notorious drug corners" of the city; a controversial plan to build a supervised injection site near the station on Hilton Street was announced in March of that year.

There is also an eastbound platform exit-only stair to the northeast corner of the intersection.
