Subway service resumes for much of the system Thursday, but service below 34th street will remain suspended. All seven of the tunnels under the East River were flooded in the storm, but the Metropolitan Transportation Authority said that three of these would be clear by Thursday. Mayor Bloomberg said that subway service between Brooklyn and Manhattan would be suspended at least until the weekend. Buses began running regular routes on Wednesday.

Oct. 31: Bringing the Subway Back The first step in restoring New York’s subway system is getting the water out. After that the Metropolitan Transit Authority faces a more daunting task — inspecting, cleaning and repairing all of the electrical components that are crucial to the safety of the trains. Critical signal systems that prevent train collisions will need to be evaluated. The segments of wiring that detect trains along every part of a track, connections to the signals, and connections to control rooms will all need to be cleaned of salt water, which can cause corrosion, and tested for damage.
Power to propel the trains is conducted through the electrified third rail of the tracks, which were shut off ahead of the storm. The rails will have to be cleaned of corrosive salt water deposits and inspected for damage before power is restored.
Communications, pumps and vent systems that release exhaust also run on electricity and will have to be tested and repaired if damaged. In stations where water reached the mezzanine level, fare gates, which have electric and communication

Oct. 30: Work Begins on Flooded Subways Seven subway tunnels under the East River were flooded by the storm, most of them in Lower Manhattan, where a 14-foot storm surge topped subway entrances and grates.

As of Wednesday afternoon, only small pockets of power had been restored to the area below 34th street, and traffic lights were not operating. In an update Wednesday, Mayor Bloomberg said he expected that most power in the city would be restored bySunday, when the New Y ork Marathon will be held. Governor Cuomo said that Westchester and Long Island were likely to wait longest for full power restoration. Track power outages in the region. »

New Y ork City bridges re-opened Tuesday afternoon, while the Brooklyn-Battery Tunnel and QueensMidtown Tunnel remained closed after severe flooding. Restoring the tunnels will present one of the most serious challenges to the city; once pumped out, they will need to be cleaned of sludge and debris. According to Governor Cuomo, the PATH tubes between New Jersey and New Y ork have been entirely filled with seawater. LaGuardia airport remains closed, and the Port Authority has given no official estimate for re-opening. JFK and Newark airports began to receive some flights on Wednesday. Flooding on Long Island has suspended most service on the LIRR, but the Ronkonkoma and Port Washington branches will partially resume service on Thursday morning. Service on the lower Harlem Line of Metro-North was partially restored Wednesday, but the railroad's other lines remain suspended. View latest service information. »

Five of New Y ork’s 14 wastewater treatment plants are in the lowest-lying areas of the city, within the mandatory evacuation zone. When the plants get filled to capacity or flooded, sewage and stormwater mix and bypass the plant, flowing directly into New Y ork’s waterways — and now, into flooded streets and buildings.

The storm surge flooded parts of the Manhattan waterfront, neighborhoods including Red Hook in Brooklyn and Long Island City in Queens, and coastal areas in Staten Island. FEMA sent a four-person "unwatering" team to drain out downtown.
Flood waters reached the corner of Canal and Hudson Streets. Most of Manhattan south of 34th Street lost power Monday night because of flooded electrical equipment.
