However, during the repairs the damages were found to be more severe than expected, leaving an even shorter remaining lifespan. As a consequence, the simplified modernization was halted and the technical supervisory authority of Berlin ordered to retire all F79 from 2019. By 2018 22 of 35 units were already pulled from service, stripped for spare components and subsequently scapped as a result of their excessive structural damage. The last F79 unit (2710/11) was retired in
October 2021.

December 2012. All modernized units remain fully

All F84 and F87 already underwent a small refurbishment in the late 2000s, where the brown interior color was changed to the light grey of the F90 and F92. An exclusion is the F87 unit 2826/27, as this unit was mothballed for several years and was not refurbished before returning to service in 2013.
688:
Differing from all previous batches and classes the F84 to F92, built between 1984 and 1994, were the first BVG trains to feature sliding plug doors instead of pocket doors. This allows for a simpler car body construction and easier cleaning. Additionally, the front was slightly altered by using a

While the modernization of the F74 and F76 was still ongoing, it was discovered in 2015 that the F79 series suffered from structural defects, allowing only for eight more years of service and only if the units underwent repairs. The planned modernization was subsequently cancelled. The units that

Already in 2006, the first Class F unit (2500/01) was dismantled to receive material samples in order to judge the feasibility of a modernization. As the car bodies turned out to be in a good condition, all remaining F74 and F76 units underwent an extensive modernization and refurbishment program

The F trains are 20 centimeters longer than their predecessors, allowing wider doors and cabs. Moreover they are the only Berlin U-Bahn class featuring transverse seating, with the exception of one Class H unit (5018) where transverse seating was implemented as an experiment.

All F79.3 were retired between 1999 and 2003 as spare parts for the early three-phase propulsion became harder to obtain, increasing maintenance costs. Two units are preserved as training vehicles for the Berlin fire department and are stored in an unused tunnel near

The F76 unit 2578/79 was the first underground train in Europe to feature an experimental three-phase propulsion. As this was never intended for long term service, the unit was re-equipped with a regular direct current propulsion in 1980.
