I think the timing is 2018 but don't take that to the bank. Metro-North owns the line to the CT line. The Housatonic RR owns the line beginning in CT. I have been encouraging the development of the trail to downtown Danbury. If that happens, one day (I will not be around to ride it), it will link to the Norwalk River Valley Trail. In Norwalk a rider will have the choice to ride to NYC or Montreal.

Danbury is without bicycling infrastructure, except a few bike racks; there are no signs, paths, bike lanes, etc. The Mayor has pushed back on biking for over 10 years. The current police chief does not seem to be interested.

Having said that, the current leader of City Center is a supporter and likes the idea of the Rail-with-Trail to downtown from the CT/NY line. He is actually looking at a bike share program which I think is pre-mature but good to know, I am not the only one trying to promote bicycling in Danbury.

This is likely more information then you were expecting. Given I do not know your interest, I will stop here and be happy to respond to any of your questions.
