The City of Portland is in the midst of installing a major improvement to its light rail train system. The Portland Mall Project will allow the trains to make a loop through the downtown core and will increase capacity for the growing rail network.

Northwest Signal Supply (NWS) had a large role as a vendor for this important project. Among the components that we manufactured and supplied were decorative aluminum housings for the vehicle signals, pedestrian signals and signs. Over $600,000 US worth of housings were sold.

An important design detail of the housings was that they had to accommodate normal mounting hardware used in the signal industry. For example, the pedestrian signals were required to mount to poles using standard “clam shells” and the housings had to be removable without interrupting the operation of the signals. Our engineering staff worked closely with architects to satisfy these functional requirements while at the same time creating the right “look”.

NWS also produced all of the catenary poles and traffic signal poles for the project. Our Voyage 2070 software was selected for the complex task of controlling light rail trains, motor vehicles and pedestrians at the signalized intersections. The installation of all of this equipment was performed by Tice Electric, a leading electrical contractor in the City of Portland.
