The prototype electric interurban railroad Chicago, north Shore And Milwaukee, did not feature climate controlled air conditioned passenger trains back in the day. The open windows on preserved car # 714 shown here in the East Union Depot, demonstrate that a ride from Chicago to Milwaukee, required open windows to help keep somewhat cool at high speeds on hot summer days.
