The latest in a series of videos about the progress being made in the MTA/LIRR East Side Access (ESA) project. When completed, ESA will reduce commuting times by as much as 40 minutes a day for about 160,000 customers who currently travel to Penn Station and then must take a subway, bus or walk to the East Side. It will also reduce passenger crowding levels at Penn Station and thereby enable Metro-North trains to access Penn Station for the first time.
Tunnel Boring Machines (TBM’s) – The machines will create four tunnels under Sunnyside Yard in Queens, connecting the tracks of the Long Island Rail Road Main Line with the tunnel under the East River that leads to Grand Central Terminal.
The tunnels, to be completed in October 2012, are the last to be built as part of East Side Access.
Two separate machines that are excavating tunnels and caverns in the bedrock under Manhattan are on schedule to complete their work this May. The machines were named Tess and Molina by sixth graders at I.S. 204 in Long Island City. – LIRR2010 on YouTube
