Those mysterious, often missing metal straps that cover the concrete ceilings in some stations.

Good guess bu no

Wild guess: the exhaust is hot enough to melt or damage the old slats?

close but no
 
Here's a little hint - the issue specifically is with the roof-mounted HVAC packages. They blow the air upwards, whereas all previous subway cars had underfloor equipment with roof-mounted intakes.

They stain the ceiling tiles?
 
Guessing games are fun!:rolleyes:

Is the exhaust condensing on the slats and causing some kind of problem?
 
Ever wonder why they are taking off those ceiling strips at stations and why the TR ceiling fans are not on when they go through stations.

Who ever figures it out first Ill give them a TR trinket
Is there an condensation issue from the hot/damp outflow of the air conditioners on the ceiling strips?
 
No you guys!! THINK!!

The HVAC is blowing air "up" into the ceiling; the air this then forced "down" causing the train to lift up off the tracks, through the ceiling, through the earth and up into orbit.

;):p
 
I'd think the air being pushed up into those metal slats would stir a lot of dust up.

At least at first ... once it's happening every day, there would be none left to stir up.


BINGO! Give the man a cigar

There is always dust
