Item, when the M-2's were brand new and in their testing stages (burn-in)
they were still technically owned by GE as the railroad did not accept them
until they successfully completed the burn-in proceedure. GE leased a
facility on the L.I.R.R. at Shea Stadium and did major repairs and also
modifications there. The cars would be towed to that facility as required.
I do not know about today but not too many years ago, Metro-North was
"light years" ahead of the Long Island when it came to maintenance and
cleaner cars. I suspect that may still be the case today.
The last time I rode the L.I.R.R. was out to Rockville Center in August of
2000 for the N.O.A.T.C. timetable collectors convention. Both ways, the
train consisted of M-1's that were rough riding, dirty, crowed and with
crabby crews. Both ways we were close to on time though.
I would guess that the shop facilities are far superior on Metro-North as
compared to the L.I.R.R.
Another item, back around 1982 or so, I had a regular job working on the
Harlem out of GCT. I ran a local out of GCT in the AM to NWP and
returned on a commuter express that only made a couple of stops enroute
but we always seemed to get the former GTE cars that the L.I.R.R. could
not keep running. These cars had the turbine equipment generally
removed and ran as sort of M-1's with their own set of technicalities and
problems. The L.I.R.R. could not make them run on their own even on
electric so they were sent to NWP where the forces found a way to make
them run at least some of the time. These cars seemed to follow me on
a couple of different jobs and trains but I never liked them. Although they
could and did run with M-1's, most of the time they ran by themselves as a
four car train.
