Putnam County officials have held a virtual update on a study to connect Danbury train service to Metro North's Harlem line via the old Maybrook railway.  The type of service and how often trains would run is being looked into, along with the needed infrastructure improvements.  Currently, it takes about 122 minutes to go from Danbury to New York City.  One proposal is to build a new ADA-compliant platform at the historic train station on White Street, creating a 104 minute trip on a full service electric line.  The study also found that this could bolster plans to extend rail service to New Milford.  Another proposal is to have a shuttle take riders from Danbury to Southeast.  The study also looked into a battery-powered or electrified light-rail vehicle.  Those options would result in a 111 minute trip.  Some of the challenges of connecting train service include wetlands, noise-sensitive land uses and nearby residential neighborhoods.
