Buses will operate in places of trains along the Danbury branch of Metro North for the next three Saturdays because of planned testing of grade crossings. The first three buses departing Danbury for South Norwalk will leave at 7:37am, 10:37am and 1:37pm. That is 12 minutes earlier than the normal train schedule. The first three buses departing South Norwalk for Danbury will be at 9:09am, 12:07pm and 3:07pm. That's 6 to 8 minutes earlier than trains normally run.
In November, the Connecticut Department of Transportation and Metro-North completed a new signal system project for the entire Danbury Branch. Branch Line service was expanded as the result of the project upgrade and construction of several portions of parallel track, or sidings, allowing for the ability to operate more than one train along the corridor at a time.
The new technology train detection system that controls the closing of a gate crossing sometimes activates with no trains approaching, despite the fact that this system was comprehensively tested at each crossing prior to being activated along the right-of-way.
The DOT is making modifications to the eleven grade crossings.
