How old is your subway train?

Last month, as the end of Albany’s legislative session loomed without an agreement to fund the $14 billiongap in the MTA’s Capital Program, transit advocatesstaged a premature funeral to mourn the potential loss of new subway cars.

Which got Metro wondering, how old is the subway train you’re sitting on right now?

If you’re riding a C, J or Z train, it could have been built in1964, the last chance to be born a baby boomer, the year Dr. Martin Luther King Jr. won the Nobel Peace Prize and when The Beatles’ “I Want to Hold Your Hand” topped the charts.A stamp cost 5 cents, and a trip to the movies $1.25.

The MTA currently has 222 of the R-32 “Brightliners” running on the C, J and Z lines.

The MTA’s youngest cars were introduced the year the Secret Service cut three agents’ assignments short, sending them home from the Netherlands after a night of drinking that left one passed out in a hotel hallway. That same year, LeBron James returned to Cleveland, and the world’s most eligible bachelor, George Clooney, got hitched. Sound familiar? It just happened. In 2014, 91 new R-188 trains were put into service on the 7 line.

The age of New York City subway trains vary by model type, and the year they were put into service.

The MTA is expecting to introduce a new class of R-179 trains, still in production upstate, in 2017 to replace the oldest trains in the system.
