Rawson, Lowery, and Bliss will never be removed because of the dual street signs outside of those stations. Instead of removing outdated names, another option is to have the City restore them, then they will become current. A few other once non existing station names are guaranteed to be preserved in the future because the City has already taken action to rename or co name areas near the subway stations
6 Av (L),
110 St stations (1), (2)(3), (B)(C),
E 143 St (6).
Restored in the future
E 177 St (would be the 4th time MTA had to completely restore a station name they previously removed)
Honorable mention:
Continental Av (no longer on the subway map, but still in the station.)
The old names on the were preserved recently (though will likely be removed from the stations in the far future). At one point MTA stopped removing historic names due to complaints. Lincoln and Fisk on the are in danger of being removed next since they weren't recently renovated. Unless they want to restore Lincoln and Fisk via the City Council.
