Summit located 14.1 miles from Columbus Union Station sat on the top of a long grade that started at the Scioto River. It was here that trains could be switch from one track to another and where, in the steam days, helper locomotives would be cut off and sent back to Columbus. The tower had a manual lever plant. Summit interlocking tower was located between East Columbus tower on the west and Heath tower on the east. It was a B&O tower staffed with a B&O operator.
