GE Transportation Systems Global Signaling is designing, furnishing, installing and testing the train signaling system used for the 14-mile Central Link light-rail project.

The signal system will control the movement of all the trains along the entire initial segment of the Central Link. It will also enable joint bus and train operations inside the downtown Seattle transit tunnel.

The signal system will ensure the safe operations of Central Link, including a wide array of features ranging from systems for observing speed limits and train separation, to granting signal priority to light-rail trains at street crossings. Other examples of signal system functions include coordinating train yard operations and controlling gated street crossings.
