the Derby–Shelton station and was expected to be completed in late 2015. Some of the 16 grade crossings on the line will be permanently closed, while others will have gates and flashers installed to prevent accidents. The entire project was scheduled to be completed in November 2020 and will cost $73 million. Centralized Traffic Control was activated on November 7, 2021. Taking advantage of the newly constructed signal system, an increase in service frequency from 15 to 22 trains per day (12 southbound, 10 northbound) was implemented on July 10, 2022 with super express connecting trains from Bridgeport saving commuters up to 60 minutes on their round-trip commute time. More trains are scheduled to come in the cumulative years when ridership yields it. Stations The following connecting services are available to Amtrak, Metro-North Railroad, Shore Line East, CTtransit, and Greater Bridgeport Transit Authority. Rolling stock The Waterbury Branch uses 2008 Brookville BL20GH and GE Genesis P32AC-DM locomotives and Shoreliner passenger coaches. It has also used Mafersa coaches originally purchased for service on Shore Line East. Prior to the arrival of push-pull coaches, the branch used self-propelled Budd RDC and SPV-2000 railcars, the latter of which were later converted to coaches. A typical shuttle consists of three cars.
