Network Infrastructure Upgrades for Security System Phase 4 – MNR New Haven Line and Branch Lines

The Connecticut Department of Transportation (CTDOT) has initiated a security program to install a closed-circuit television (CCTV) system on the New Haven Line and three branch line passenger stations and a major bridge. This project includes establishing the network infrastructure to support a new CCTV system and the interface to the fiber backbone at the passenger stations, traction power substations, security node house, and head-end equipment at the New Haven Rail Yard Component Change-Out Shop. Phase 4 involves upgrades to the New Haven Line from Mile Point 26.20 to Mile Point 33.15, Greenwich to Stamford Station, along with the New Canaan, Danbury, and Waterbury branch lines. Garg Consulting Services, Inc. is responsible for design services on three branch lines, including 4 passenger stations along the New Canaan Branch, 6 passenger stations along the Danbury Branch, and 6 passenger stations along the Waterbury Branch.
