Metro-North Railroad moved to hourly service at 4pm Thursday. The railroad said it may need to further reduce or suspend service on some portions of its territory if conditions warrant.
Just a third of Metro-North's usual customers took trains to New York Thursday morning.
Metro-North relied heavily on its diesel fleet during the day. Those are the trains usually running on the Danbury Branch Line. Snow blowers and patrol trains were operating to clear the tracks, but higher-than-predicted rates of snowfall had the potential to further affect service.
Metro-North uses special third-rail shoes to clear off snow and ice buildup. The commuter railroad said it will pay particular attention to the New Haven line's overhead catenary wires that are vulnerable to ice and snow.
The railroad also has treated door panels with anti-freeze agents and put in place rail-mounted snow-fighting equipment.
