The culprit? Road salt dripping from a bridge:

Thanks interesting video. I don't think it was actually a fire though, I think it was an arcing caused by the salty water dripping down.

According to a presentation I attended some years ago by Metro-North's Power Dept., the problem was worse when the line through Mt. Vernon had catenary (which is why they moved it further east).

This is true except that the direction on the New Haven is east. In the past this was a real trouble area especially in wet weather and in the winter with road salt on the overhead bridges.
