Yes, I’m very aware that sulfur compounds are what causes the rotten egg smell, but why would there be sulfur compounds in a metro station?
I saw a piece of litter on the street this morning. Any explanation?
L’Enfant Station smelled like sewage– i took the first train — going in the WRONG direction just to get away from the stench
I used to eat at that Taco Bell all of the time. Ah… good memories.
Its most likely the breaks….. occurs every now and then. could also be the sewer smell filtering through underground:
It’s not the breaks. I know that smell. This smell like someone had lit off a stink bomb 30 minutes earlier. I almost gagged it smelled so bad. Not the same smell as brakes.
I have been told by station attendants that it is the brakes on some of the trains.
I did not smell it, but the rotten egg smell (nominally H2S or other compounds with S-Hydrogen groups in them) can indicate a gas leak from somewhere. Natural gas is odorless so small amounts of S-H containing compounds are added to make detection easier. Not sure how strong the odor was at this sighting (smelling), but if it was as strong as Novasteve claims, AND it was a gas leak, there would have been a dozen trucks there within seconds. This is what happened in Colonial Village a few weeks back in the middle of the night. Thus- I do not have a clue what this was. Prank with a stink bomb? Someone probably knows as there are gas sensors in there- at least there used to be.
To clarify, as some folks are doing above: Sulfur has no smell. Compounds where S has been combined with other elements, particularly H, do.
Brakes do not smell like this. That is an entirely different sort of nasty. I believe these are more like phenolic resins.
