Seen here along the northside of West Kinzie Street between Pulaski Road and North Kilbourn Avenue, is the Union Pacific M-19A diesel shop.
This is located at 400 North Pulaski Road. This is a very busy locomotive terminal on Chicago's westside. Mid day hours can find Metra engines being serviced prior to the evening rush hour at this location. This is on the Metra / Union Pacific -West line to Elburn Illinois. Prior to 1998, this was the Chicago & NorthWestern Railroad line.
