Andy Byford, once New York City Transit’s “train daddy” and now Amtrak official charged with overseeing the Penn Station redesign, said on Wednesday that he needs to “fully come up to speed” on dire warnings about the Gateway Tunnel project.

Officials, including U.S. Sen Chuck Schumer (D-New York), warned on Tuesday that the Gateway project will come to a screeching halt if the Trump administration does not unfreeze federal funding for it by next Friday. The Gateway project directly impacts Penn Station, as it is replacing two 110-plus-year-old tunnels underneath the Hudson River that bring hundreds of Amtrak and New Jersey Transit trains into the hub each day.
