Directly across from the elementary school Amtrak plans to build a ventilation facility to “provide protection for train passengers in the event of an emergency,” according to the Amtrak website. This structure will include emergency fans that “could extract smoke from the tunnel in the unlikely event of a fire.”
If something goes wrong, they vent the bad air coming out of that tunnel across the street from a black elementary school. Their planned management of hazardous emissions is what’s in question.

I doubt it’s /just/ smoke ventilation. Sure, it’s primarily there for fire safety.
But it probably provides ambient ventilation for the tunnel too. Tunnels with trains get hot. Most things, living or inanimate don’t like heat.
And if it’s always ventilating, it’s also might be expelling brake and metal dust from passing trains.
But all speculation. I’m not a train engineer, so I’m probably wrong.
