There's several MP15s that were killed off one way or another, my main bet is the two that died before they got a chance to be repainted. Hopefully not 3100. Also, re;maintaining, who says these things will need to run?
The 3100 lost it's cab when turned into a HEP car for the C-1's,not worth saving,it was a butchered job.
You still need to maintain the outside shell,need to spend $$$ and time to do a proper paint job.
LIRR no long has a paint booth,any repaints were "quick and dirty" brush and roller paint jobs with little or NO surface prep.
