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. 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. I need to fully come up to speed with that.”Byford also insisted that whatever the fate of the Gateway project is, the Penn Station renovation should still move forward. “Penn Station, do nothing, is not an option,” Byford said. So we’ll see what pans out, but my project is, which is what I’m focused on, remains critical.
