   They were supposed to run on 3rd rail while in the tunnels and terminal.   
   However, as they aged, this didn't work so well, and sometimes they had   
   to use diesel.  GCT stunk from the fumes when that happened.   
      
   In the dark days of the 1980s, they may have been forced to use   
   a straight diesel at times.   
      
   The opening of the upper Harlem Line electrification and new MU cars   
   alleviated the situation quite a bit, as did rehab of the FL9's.   
      
   Ironically, when new, the FL9's had a lot of teething pains for   
   what should've been pretty basic technology.  Despite that, they   
   ended up staying in service for nearly 50 years, very long for   
   a diesel locomotive.
