I have a slight fondness for NYC's oldest subway cars, the rickety Budd R32s that trundle along the city's C line. They started operation in 1964 and are still in service.
The thing I'm wondering is: do you know of any older subway cars in service? Any metro system in the world is welcome, and I welcome any interpretation of what exactly a subway system is.
