Fog in stations.

Anyone here ever been in a station on certain days & the whole place was hazy off into the tunnel darkness? Specifically exchange place, hoboken, and pavonia/newport.

Pavonia has constant water leakage problems. There's a pneumatic ejector pump at the south end of the southbound platform, and you can hear it wheezing and sneezing. A little to the north, one of the junctions is very close to the Holland Tunnel - something like only 16" of soil between the top of the PATH junction and the bottom of the Holland Tunnel drainage invert. I expect a good deal of water comes in from there. Hoboken was always a special case - the "Hoboken smell" in the PATH station was due to the presence of iron-reducing bacteria that were actually eating the iron rings. With all those sources of water, you have combinations of hot cars in cold tunnels or cold cars in warm tunnels, which leads to condensation. Also, don't forget that you have the emergency exit south of Pavonia (the powerhouse) and the 15th Street shaft, which are going to pull in ambient air at whatever temperature/humidity it is outside and drop it directly in the tunnels.

Yea, it's just weird, you go down and all the sudden place fills with smoke-like mist. Only happens at pavonia newport and exp, never in 8 years seen it at hoboken.
