Gut Time. Perhaps the end of sparse paint is nearing for Connecticut Department of Transportation's P40DC fleet as Shore Line East Train 3645 crosses The Gut from the Niantic River to Niantic Bay in Niantic, Connecticut with CNDX 840 leading on Friday, February 25, 2021. This bridge opened by Amtrak in 2012, replacing a 1907 New Haven Railroad span. The recent re-arrival of CNDX 6711 in the area after shop time at Amtrak's Beech Grove, Indiana facility will trigger the first appearance of the CT Rail corporate scheme on these veteran units. While SLE service began in 1990 as a temporary measure to ease congestion during construction on Interstate 95, it has since been made permanent and solidified its place in transit, now entering its 4th decade of service.
