Between 26th and 31st Streets, Belt Railway of Chicago had a freight yard. As the yard's name implies (Hawthorne), an important customer of this yard was probably the Manufacturers' Junction Railway that serviced the nearby Western Electric Hawthorne Works. The map indicates that there also was an American Brake Shoe Foundry served by this yard. Given that both of these industries are now retail stores or vacant land, it is no surprise that the yard is now gone.
This was a relatively cheap yard because it was not elevated and no roads crossed it.
