Southeastern Pennsylvania Transportation Authority (SEPTA) recently awarded Union Switch & Signal Inc. (US&S) the Kay Interlocking Re-Signaling Project contract. Terms weren’t disclosed.

To be completed in October 2008, the project features a new five-track interlocking design and interfaces with the SEPTA West Interlocking to the east and Amtrak Zoo Interlocking to the west. The system will provide fully protected, bi-directional operation on all tracks.

The project will consist of design, fabrication, factory testing, and delivery of a new remote-controlled interlocking that includes all instrument houses, control panels, instrument cases, signal power transformers, impedance bonds, track wire, junction boxes, position light signals, US&S M-style electric power switch and lock layouts, and the MicroLok ® II vital and non-vital interlocking control.
