In 2010 and 2011, state and federal funds were awarded to Connecticut (and Massachusetts) to construct the Hartford Line, with a southern terminus at New Haven's Union Station and a northern terminus at Springfield's Union Station. According to the White House, "This corridor [currently] has one train per day connecting communities in Connecticut and Massachusetts to the Northeast Corridor and Vermont. The vision for this corridor is to restore the alignment to its original route via the Knowledge Corridor in western Massachusetts, improving trip time and increasing the population base that can be served." Set for construction in 2013, the "Knowledge Corridor high speed intercity passenger rail" project will cost approximately $1 billion, and the ultimate northern terminus for the project is reported to be Montreal in Canada. Train speeds between will reportedly exceed 110 miles per hour (180 km/h) and increase both cities' rail traffic exponentially.
