John Burns, General Contractor, completed a $5.3 million project to convert Metra’s 51st Street Tie Station into a Traction Power Substation. This Traction Power Substation converts Alternating Current (AC) power provided by the local utilities into Direct Current (DC) power utilizing the process known as rectification. The DC power is now used on Metra’s Electric Line. John Burns built this substation from the ground up and integrated it into the existing Tie Station to increase DC power capacity. The Traction Power Substation that John Burns installed and commissioned is now housed in a pre- packaged enclosure. The equipment includes AC switchgear, rectifier transformers, DC switchgear, bus ducts, SCADA, distribution panels, and auxiliary systems. John Burns completed the underground casing bore for the duct bank to connect two precast concrete manholes that were set.
