Construct a tie house (at the intersection of Milwaukee/Canal/Lake Street) and two new substations (at
Barry/Kimball intersection and Damen/Milwaukee intersection) to support traction power needs on the
Blue Line. These assets will support increasing ridership demands as well as the power needed to
support 5000 and 7000 series rail cars. The location of the tie house and substations were determined
by the Blue Line Load Flow study, which identified areas that were likely to experience traction power
issues.
