Alon Levy in The Register Citizen

Another New York City project that could benefit commuters would be efforts to reduce speed restrictions along the last mile of underground track heading into Grand Central, where trains currently crawl at 10 mph, according to Alon Levy, a fellow at New York University’s Marron Institute based in Berlin. Moving at the speeds European commuter trains do going into the station, Levy said, could reduce the length of a trip by as much as six minutes each way. ‘It’s literally the biggest and most cost-effective thing they can be doing, they’re just not thinking about it,’ Levy said.
