Rail & Transit Engineering

The Darien Railroad Station Improvements Project is part of the New Haven Line Improvement Program. This project aims to address the structural deficiencies at the station through the replacement of the existing concrete double-tee platform superstructure, ramps, stairs, railings, catenary structures, and rehabilitation of the existing elevators.

Garg Consulting Services, Inc. (Garg) is providing electrical engineering and catenary design services for this project. Specific tasks include:

• Design of the catenary attachments and reinstallation of the overhead contact system that are related to the replacement and relocation of the four catenary portals.
• Design of an emergency generator / uninterrupted power supply.
• Development of a short circuit and protective relay / circuit breaker coordination study for the electrical system, electrical load calculations, and electrical one-line diagram.
• Design of a station grounding and bonding system which will eliminate touch and step potential from rail return power and deter copper theft.
• Development of power and lighting panel schedules, lighting schedules, electrical site layout, and electrical demolition plans.
• Design of electrical upgrades related to a heated platform system, elevator rehabilitation, new security system, communication system, and other replaced / rehabilitated systems and equipment associated with this project.
• Perform Photometric Analysis for the replacement of the existing lighting with LED lighting and new lighting as required.
• Utility design (dry standpipe) and electrical utility coordination.
• Construction staging / railroad staging, and sequencing related to design work.

Garg will also be providing contract documents (including developing all front-end documents), bid phase services, specifications / special provisions, cost estimates, and schedule input related to design work.
