In my nearly 20 years of navigating New York City's ever-changing transit system, I'd thought I'd seen it all, whether it was the revival of the Second Avenue Subway line, the extension of the 7 train to 34th Street Hudson Yards or the recent arrival of LIRR to Grand Central Terminal. Of course, just as I departed the city, the MTA unveiled Open Gangway cars to make things more exciting for subway riders on the C Line, a project years in the making. Stretching from 168th Street in Washington Heights to Euclid Ave in Brooklyn, riders will now be able to walk all the way through the R211T cars without feeling boxed in.
