Train fares will be waived on Friday, Gov. Dannel P. Malloy said late Thursday. Malloy called the resumption of service \u201cthe result of night-and-day repairs and coordinated equipment logistics by a dedicated workforce in the wake of the devastation left by Hurricane Sandy.\u201d The New Haven Line is operated by Metro-North under contract to the Connecticut Department of Transportation, and is the busiest rail line in America, serving some 125,000 daily commuters. \u201cGiven the damage and disruption we sustained up and down the line as result of this storm, a return to full main line service in a matter of a few days is remarkable,\u201d Malloy said. \u201cMetro-North workers were deployed immediately and have been working around the clock to return us to 100% service on the line between New Haven and New York. This is great news for commuters, our state and Connecticut\u2019s economy. I thank everyone involved for their tireless efforts and commitment to customer service.\u201d On Thursday, service returned between Stamford and New York\u2019s Grand Central Terminal. Beginning Friday morning, regularly scheduled weekday service will resume on the entire line between New Haven and Grand Central Terminal. New Canaan, Danbury and Waterbury branch lines will be returned to service as soon as possible. There are approximately 38 million passenger trips annually on the New Haven Line.
