Subway Savant

Workers pumping out the 14th street tubes which carry the L Train under the East River. From the MTA Flickr. 
The tunnel was flooded the worst of all 7 sets of tubes washed out, part of the reason it was left until last. 
I also have been told by those in the know that the CBTC system in the tunnel has been damaged, slowing recovery. 
CBTC, or computer based train control, is the fancy new signaling system used on the L line. It enables nifty new features, such as the countdown clocks, and greatly enhances the capacity of the line in terms of trains per hour, but ironically, it has proven much more prone to failure after disaster than the old system, which is basically just a metal rod that sticks up from the track and stops the train if it goes past a red signal. The more you know.
