Real progress toward improving local commuter rail service is now underway in Derby, and the successful revitalization of Derby\u2019s downtown depends upon good regional transportation options. The State of Connecticut, as part of its Let\u2019s GO CT! Transportation initiative is making some important investments in the Waterbury Branch Line (WBL) of Metro-North, which runs from Waterbury, through Derby, to Bridgeport. The WBL currently is a single track rail system with no passing sidings, but not for long. A passing siding is a portion of track that allows one train to pull off to the side to let another pass. The first of four planned sidings is currently under construction in Derby, enabling more frequent and convenient rail service. The WBL is considered \u201cdark territory\u201d because it has no communication signals along the line. The signalization deficiency, which likewise restricts service capacity, is being addressed as well. \u201cAs we speak, the Connecticut Department of Transportation has started the design of a signalization system for the WBL,\u201d said Mark Nielsen, assistant director of the Naugatuck Valley Council of Governments (NVCOG). NVOCG oversees the region\u2019s transportation networks. Nielsen further stated that \u201cthe State is committed to installing Positive Train Control along the WBL to ensure trains can operate safely.\u201d \u201cWe are excited to see these significant investments being made to our local rail line,\u201d said Mayor Anita Dugatto. \u201cThey are a great complement to our downtown revitalization efforts.\u201d Why is the improvement of the WBL important to the revitalization of Derby\u2019s downtown? Because the best opportunities for investment and sustainability rely on a safe, dependable, and convenient public transportation network. Derby\u2019s compact city center and accessibility to a variety of transportation options position it well for transit-oriented development (TOD). TOD is a development scenario that includes a mix of housing, office, retail and\/or other amenities integrated into a walkable neighborhood. TOD neighborhoods are typically located within a half-mile of quality public transportation. TOD communities are especially attractive to young professionals and \u201cempty nesters.\u201d Millennials, the generation of children born between 1980 and the mid-2000s, prefer living in urban environments with walkable\/bikeable access to regional transportation, jobs, entertainment, and other lifestyle opportunities. Community members that are looking to downsize their responsibilities, while maintaining their active lifestyle, also appreciate the convenience of centrally located housing near mass transit and other amenities, allowing for continued mobility and independence.
