Several cars in the fleet were retrofitted as part of an automated-signaling test on the 42nd Street Shuttle in 1962 and were destroyed in a 1964 fire.

The R22s first entered service on April 13, 1957, starting to replace most of the IRT "high voltage" type cars.

Cars 7513, 7509, 7516, 7654, 7675, and 7686 were used as an automatic test train, which ran in revenue service on the 42nd Street Shuttle starting in January 1962.

The experiment ended on April 21, 1964, when a fire partially destroyed the Grand Central shuttle platform as well as car 7740.

[2] The majority of the fleet was scrapped, but some R22s have been set aside for preservation over the years, including: A handful of R22 cars are currently in work service: 7486 (renumbered G7486) is currently at the 207th Street Yard.
