The MTA Network
§ Provides 8.5 million transit rides a day
l About 30% of all transit rides in U.S.
l More trips than the next 10 U.S. systems combined
l Four times the trips every year as the entire domestic airline industry
l Long Island Rail Road serves 282,350 customers per weekday, busiest commuter rail in country
§ 2011 operating budget of $13.4 billion
§ Investing $24+ billion in its current five-year capital program
Economic Impact
MTA the lifeblood of $1.4 Trillion regional economy
Provides 25% of New York City’s construction industry jobs
2010 – 2014 Capital Program
l Expected to create approximately 350,000 New York jobs
l Spur $44 billion in economic activity
What is the MTA Capital Construction Company?
§ Created by the MTA in July 2003 to oversee system expansion
§ Mission: Build East Side Access, Second Avenue Subway, No. 7 Extension, the Fulton Street Transit Center, South Ferry Station (in revenue service) and manage the capital security program
§ Largest transit expansion program in the nation
§ Current project portfolio of $17 billion
What is East Side Access? A Transit Mega Project that will Extend LIRR
service to Grand Central Terminal
East Side Access - Need
§ Penn Station is LIRR’s only terminal in Manhattan l North America’s busiest train station; operations shared
with NJ Transit & Amtrak for total of 61 trains in the station during peak hours
l Overcrowded; approximately 230,000 LIRR passengers at Penn each weekday with 81,330 peak AM arrivals
l No capacity for increasing service; Station, tunnel and yard infrastructure limitations
§ Almost 50% of LIRR customers would be better served by a terminal on Manhattan’s East Side
§ LIRR cannot meet the needs of Long Island, the nation’s third largest city, or the needs of Man-hattan’s midtown economic center for workers
§ Constructing new infrastructure for ESA will allow for increased train service between Long Island/Queens and Midtown Manhattan
211 census tracts of over 100,000 residents/sq. mi. in N.Y.C.
33 census tracts of over 300,000 workers/sq. mi. in N.Y.C.
Manhattan Population Density - Only 6 other census tracts with this density in the entire nation
Manhattan Employment Density - Only 5 other census tracts with this density in the entire nation
Need for Expansion East Side Access is in the densest population
and employment areas in the nation
East Side Access - Benefits
§ First Expansion of LIRR in over 100 years
§ Increases East River tunnel capacity by over 50%
§ Supports job growth in area surrounding Grand Central Terminal
§ Relieves congestion at Penn Station
§ Saves thousands of East Side-bound commuters 40 minutes per day
§ Will serve approximately 160,000 customers per day
East Side Access - Scope Upper Platform
Lower Platform
§ 7.75 miles of new tunnels in Manhattan & Queens
§ A new LIRR terminal station beneath Grand Central Terminal l 8 tracks, 4 platforms l Mezzanines and
concourses
§ New yards and shop in Sunnyside, Queens
§ Budget: $8.192 B l Including $463M rolling
stock and $401M regional investments

Mining New Tunnels and Building New Structures Under the Rail Yard
How do you get from…
By tunneling under the busiest railway interchange anywhere in the country
And under an existing subway and elevated rail line
HERE
THERE
Under an active rail storage yard
And in Manhattan, we must blast and build…
Under GCT, the country’s premier rail terminal
While the second largest commuter railroad continues to operate
And under blocks of the most valuable Real Estate in North America
Thank You!
