Hello,

I saw on a moving 96ts the other day that one of the rail cars had a
blue light on.

The interesting thing was that the train did not extend its dwell time
beyond what would be normal.

Does the blue light indicate a door fault? I'm guessing, were that the
case, that the line controller ordered the driver to engage the
interlocking. But even if there was a door fault, would not the line
controller have ordered the driver to dump the load?

I saw this train during non-peak hours, BTW.

I think it means it's a de-icing train.
