A bill supporting a study for commuter rail expansion has passed the New Hampshire House.
The House bill on Thursday includes the federally funded study as part of the 10-year state transportation plan.
The project would extend passenger rail from Boston to Manchester, N.H., with two stops in Nashua, a stop at the Manchester-Boston Regional Airport, and a stop in downtown Manchester.
Republican Gov. Chris Sununu and the Governor's Advisory Commission on Intermodal Transportation included $4 million for project development in the state's 10-year plan.
