[edit] History and Description
There were 200 R68A cars built from 1988–89. They first entered into service in April 1988 on the D train. They replaced the last R10s, R27s, and unrebuilt R30s all of which were retired between 1989-1991.
R68As are currently based out of the Coney Island Yard and assigned to the B train. They are scheduled to remain in service until at least 2025 [1] and the MTA is proposing mid-life technological upgrades for the fleet, including LED destination signs and automated announcements.[2]
[edit] Differences Between an R68 and R68A
- The door to the operator's cab slides open on an R68A as opposed to swinging open on an R68.
- The R68 and R68A fleets have different window frames.
- Unlike the R68s, the R68As do not feature rims around the red door indicator lights.
- The "MTA New York City Subway" logos are arranged differently between the two car types.
- The side ribbing runs all the way to the car ends and side doors on an R68, but taper off on approach on an R68A.
- Only the R68s have a metal bar separating the side sign from window, while the R68A has one solid pane of glass.
- The R68s have unit numbers in the 2000-series while the R68As have numbers in the 5000-series.
- The R68 and R68A fleets have different traction motors.
