Sure did. McLellan and Warrick in their book The Lake Shore & Michigan Southern Railway mentioned commuter service starting between Chicago and South Chicago (at the time Chicago's downtown passenger terminal was referred to as the Van Buren St. Station) in July of 1872. Droege's Passenger Terminals and Trains indicated 88 suburban trains out and 87 such trains in on a daily basis in 1912-1913. The CRI&P by comparison operated twice that number in and out of LaSalle during this period . The Lake Shore's daily passenger counts were not insignificant during 1912-13 with over 4,000 "commuters" traveling each way along its lines. Some forty years later In the early fifties the NYC was still running trains out from LaSalle St. Station to Gary, Porter, and Chesterton - the latter forty plus miles out on the main line before turning for a later trek back. The number of trains would of course dissipate and ultimately dry up over the next few years.
