The U.S. House passed an appropriations bill on Wednesday, and it included a 2 million dollar grant for the City of Danbury.  The money will be used to study the impact of a fast track rail service to New York City.  Danbury and Southeast officials have been looking into reviving the old Maybrook line as a commuter route from downtown to the Metro North station in New York, to connect riders with the Harlem line.  A previous 1 million dollar grant was awarded for a feasibility study.  An environmental impact study is the next step in the planning process.
