In People v. Long Island R.R., (90 Misc 2d 269 [App Term, 9th and 10th Jud Dists 1976]) the Second Department, Appellate Term affirmed the dismissal of an information charging the Long Island Railroad, a subsidiary of the MTA, with violation of the Suffolk County Sanitary Code governing diesel emissions. That court noted that since the Long Island Railroad, at the least, found it convenient to operate diesel trains, the subsidiary was exempt from county environmental rules that were in conflict.
