Does anyone else miss painted subway cars? From redbirds to bluebirds to greenbirds, the blue door R32, and the famous blue stripe Corporate scheme, the NYC subway used to be quite colorful (when the cars were not covered in graffiti). But every car from the R62 onwards has been made of stainless steel, only broken up by the temporary occasional ad/promotional wrap or Cuomo stripes. Why did NYCT move away from painting subway cars?
