"glass train"

[Bill Ravanesi <ravanesi@bu.edu>]

  Rob said,...........Additionally, A week before the testing someone had
  overheard the Incinerator owners, say that the testing should go well
  unless they have a "glass train".  Could someone explain the term glass
  train and why it would pose a problem ?  Is there any significance to their
  having to re-test for metals?

  I don't know a lot about this, but could it be "gas train" instead of
  "glass train."
  
  If so, this may mean a flame failure leading to a drop below temperature.
  Valves regulating the natural gas source may have been incorectly adjusted.
