CP243 Interlocking Project

State Project No. 0301-0181A

The CP243 Interlocking Project will include the construction of a new four-track interlocking.  An interlocking is a powered switch and signal system that allows trains to move from one track to another. The new interlocking is being constructed approximately 2,200 feet long, located on the New Haven Line (NHL) between East Norwalk and Westport in the vicinity of Norden Place, and approximately 1.5 miles east of the Walk Bridge.

In addition to the installation of six new switches and crossover tracks, the project includes approximately 6,200 feet of track realignment, overhead catenary modifications including 19 catenary structure replacements, new crossover wiring, and a power balancing station.  New drainage will be installed on the north and south sides of the tracks. 

The CP243 Interlocking project also includes fiber optic signal system upgrades from Monroe Street, west of the Norwalk River, to a new signal hut just east of the River, where signal houses will be replaced and new connections installed.  This includes mounting the signal cable on the Walk Bridge and a submarine crossing of the Norwalk River at the movable span.  The work includes the signal and submarine crossing for the Saugatuck River in Westport. 

This project is independent of the Walk Bridge Replacement Project, but will improve the dependability of operations on the mainline and shorten the distance of two-track operations for passenger services during the construction of the new bridge.
