The Federal Railroad Administration said the legislation "does not adversely affect" any of the 150 high-speed and intercity passenger rail projects currently funded in the United States. The agency said 99 percent of high-speed and intercity passenger rail funds are already obligated. Currently, 45 projects are being built or will be soon for about $2.5 billion in 15 states and Washington, D.C. Nineteen construction projects are completed.
Kevin F. Thompson, a spokesman for the agency, said in a statement Friday that the budget for passenger rail funding includes improvements for current and future "high performance" rail projects and money for corridor studies. The railroad agency will work with Congress to "identify a predictable and reliable revenue source" in future budgets, he said.
In Connecticut, transportation officials say the New Haven-Hartford-Springfield line can be launched in 2016 with federal funding already received.
Beginning in 2009, Connecticut received $40 million in stimulus spending to add a second track along a 10.5-mile segment between Meriden and Newington. The segment is part of the New Haven-Hartford-Springfield corridor that will link Connecticut's shoreline with western Massachusetts.
In 2010, Connecticut received about $121 million for double-tracking the remainder of the corridor south of Hartford and station improvements in Wallingford, Meriden, Berlin and Hartford. The state received $30 million in the following year to add a second track in Hartford.
Connecticut also is using up to $280 million in state bond proceeds for the rail line.
More money will be required to complete the remainder of the improvements and the state Department of Transportation says it will "aggressively pursue" money from Washington.
In Vermont, a $72 million rail project between Brattleboro and St. Albans was completed in 2012. The rail line, which received $66 million from Washington and $6 million from New England Central Railroad, upgraded tracks for trains to run faster, cutting travel time by 30 minutes, said Chris Cole, director of policy planning and intermodal development.
State transportation officials have a plan to extend rail service to Montreal and are working with Amtrak and U.S. and Canadian customs agencies and the province of Quebec to advance the proposal. What's needed now is a treaty signed by the U.S. and Canadian governments authorizing train and ferry service, Cole said.
"People will see it's feasible to make it happen," he said.
