I know this is only, but I do fine this tread interesting. IIRC, The 1994-1995 and 1996 Orion V diesels were having rusting issues, so bad that the buses themselves were falling apart and were therefore no longer roadworthy. That was why as soon as the 2009 Orion VII NG hybrids got delivered in the Bronx especially during the spring and summer of that year, the most of the 1993-1996 Orion Vs went bye bye. The 1994-1995 CNG units that were out of Jackie Gleason depot in Brooklyn at the time did alot better considering that JG had decent maintenance and didn't run them as hard as their diesel counterparts in other Boroughs. However, the 2010 doomsday cuts nearly did them in until it was decided to give them to MTA bus company for awhile, but came the end of September, they were sadly retired for good without any replacements as the new C40LFs would not arrive for another year.
