All the "A" cabs of the R32s and R38s have operator/conductor control panels and seat availability and all the "B" cabs have conductor-only control panels without a seat available; the "A" cabs of the R40s and R42s have operator-only control panels and the "B" cabs have conductor-only control panels, in addition to a seat being available in every cab. The R32s, R38s, R40s, and R42s are also all married coupled pairs, meaning that for example, four pairs make up an 8-car 480 feet long J train or five pairs make up a 10-car 600 feet long A train.
All other car types from R44s to present are half-length consists that each make up a full-length train, meaning that for example, two 4-car 240 feet long units make up an 8-car 480 feet long J train or two 5-car 300 feet long units make up a 10-car 600 feet long A train. All ends of the aforementioned half-length train in these other car fleets have a cab with operator/conductor control panels and a seat available. When the remaining two-hundred and twenty-four R32 cars first underwent SMS, seats were installed in all of their "B" cabs due to numerous complaints from conductors who stated that they had to stand all the way on the entire 32-mile length long A route for almost two whole hours or so.
All R62As on the 1 have red stickers; all R62s on the 3 have orange stickers; all R62As on the 7 have purple stickers; all R62s and R62As on the 42nd Street Shuttle have blue stickers.
All R46s on the F and R as well as all R68s on the D have red paint lying on the door edges.
From November 2012 to May 2013, R32s on the A only ran during rush hours and were almost never in service at all other times.
During the closure of the Montague Street Tunnel for Hurricane Sandy-related repairs, the F and R cars were swapped because Coney Island cannot regularly maintain nor inspect R46s. As a result, the W and the weekday northern R had to switch trains at Whitehall Street, depending on the schedule and the actual order that trains arrived in; R160As have also made appearances on the N and Q, and R160Bs have made appearances on the E, F and weekend R as well as the weekday southern R; whatever R160s that were left on the F still ran at all times, however.
