Starting on June 1, the Waterbury Branch was shut down for critical infrastructure work on the track, passing sidings, crossings, bridges, and the installation of signals. On a rainy morning from the Maple St. overpass in Ansonia, a PTC (Positive Train Control) test train, which consists of Connecticut Department of Transportation P32AC-DM 230 in the inspired New Haven Railroad McGinnis livery, along with a single CDOT cab car the Charter Oak 6209, heads north testing the new signal and PTC system. The train would go as far as Beacon Falls then return south. The branch resumed regular service on October 3.
