Superstorm Sandy hit island of Manhattan on Monday causing incredible damage to the city. There were countless trees downed, thousands of cars destroyed, and whole taxi lots flooded. But one of the most devastating hits and biggest setbacks for the city in this disaster was the flooding of the massive underground transit of the New York, the subway. The subway is made to withstand run off from a big rain storms but is not equipped to handle a complete flooding. This storm is considered to be the most devastating disaster in the 108 year history of the New York subway system. Not only will the water ruin all the electrical systems in the subway, but the corrosive salt could completely destroy switches, lights, turnstiles and all other controls essential to the running of the subway. In addition, the third rail, which is a third rail that conducts the electricity to the train, will be greatly affected or even ruined by the corrosive salt water. As of now the extent of the damage cannot be assessed until the tunnels are drained, which could take a week or more. One can imagine there will be thousands of electrical systems that need to be replaced. Complete rehabs of the trains and finding replacement parts will be a ong process in itself, not including just the cleanup work it will take to get the subway running again. Who knows how long it will take for the subway to get back to normal, but this will definitely affect how fast the city can get back up to speed.
