Good view

Good job going on the roof to get an actual view of the problem and not just relying in instruments or tests of the interference.  We had a similar issue at our facility where a machine would consistently have a high amount of defects at the start of the shift but would then run great all day and overnight.  On inspection of the cell, the defects were kicked out based on an automated vision inspection.  The rising sun through a plant skylight each morning would change the light profile on the part causing false rejects.  The solution was dark shielding on the whole cell and the problem did not re-occur.

Other kinds of traffic?

This raises the question of whether there aren't other kinds of traffic in between that could produce a similar effect, such as planes in the air or automobiles on the ground.

I wouldn't expect this to be a problem because when you're on the train, it doesn't change its shadowing. It is always constant, so it would modulate at DC.

Commuters wouldn't stand for degraded signal

That's a case of deductive reasoning I can follow. But I'm wondering about the zillions of commuters who are glued to their cell phones riding trains every morning and afternoon rush hour. I'm assuming no impact on cell signal or it would be front page news and trending topics on Twitter. Any thoughts as to why this isn't a more regular occurance?
