I know, but when the 97's came out, I loved the new lighting scheme, and things continued to get better through the 99's (new LED signs, padded seats, etc). (And you had the Orion V counterpart of these, the 6000's, which I heard were in particularly bad condition). The 96's interiors are nearly identical to the original RTS's of the 80's (but without the Detroit two strokes).
So I had looked to see the '97-99's spread out more (like to MTAB), but it seemed NYCT held on to them, passed down only the 96's, and then quickly began scrapping them. (I know there were a few instances of them sending a few to LGA, but they were always brought back).
Nearly the same thing occurred with the '94's (with their unique lighting. Thought MTAB still had their nearly identical former PBL '94's).
Wonder why they didn't look forward and reha the 97's to 99's instead (especially if they had problems like wheelchair lifts).
