The MTA is building a new tunnel under the East River to allow LIRR trains access to Grand Central. All LIRR trains now go to Penn Station.

Lhota says there have been problems tunneling underneath a rail yard in Queens. The MTA has brought in experts from Europe to help with developing a plan going forward.

The $7.4 billion mega project has been plagued with delays and far-off completion dates. It was originally supposed to be finished by 2015 and part of the project was even fast-tracked back in January.

Once complete, the perks will include extra trains at Grand Central and a new LIRR train station in Sunnyside.
