The period of 1960-1970 was the best time to be a subway rider as far as cars models go, because you went from the last of the first-generation types on the BMT and IRT to the beginning of the current body design and air conditioning with the R-40M/R-42. The down side was, deferred maintenance really started to take hold by the mid 60s, and sewed the seeds for the disasters of the 1970s-1980s.
In that 10-year period, you could ride Standards, Triplexes, Q cars, Lov Vs, Worlds Fair Low Vs and every R-series car ever made from the R-1s to the R-42s. And back then, until you got to the R-16/R-17 design, every car modle had its own distinct look -- even a non-railfan could tell a multisection unit from an R-10.
Fifteen years from now, there will probably be only three types of cars on the IRT (R-62, R-142 and the R-whatever-it-is-that-replaces-the-last-of-the-Redbirds), while the BMT and IND might have as many as six different styles around, if the R-32s do make it to their 50th birthday.
