Those cars are 85 feet long. The longest train we run is on the BNSF Line, consisting of 11 cars (at least one of them a cab car) and a locomotive. Those cars, including cab cars, are also 85 feet long.

A standard Metra commuter rail car, specifically the iconic stainless steel "Gallery" bi-level cars used in the Chicago metropolitan area, has a length of approximately 85 feet (about 26 meters). This 85-foot standard is common across most North American passenger rail equipment, as it maximizes passenger capacity while still being able to navigate the curves and clearances of the existing rail infrastructure. These cars are typically 10 feet wide and stand about 15 feet 10 inches high to accommodate the two levels of seating. The "Highliner" electric cars used on the Metra Electric District also follow this 85-foot length standard. Because of their immense length and weight (often around 130,000 to 150,000 pounds), these cars are designed with "double trucks" (two sets of four wheels) at each end to distribute the load evenly on the tracks. When Metra retires these cars, they are often sought after by rail museums or private collectors precisely because of their impressive scale and durable construction, which has allowed some cars to remain in service for over 50 years.
