Back-Out Punch

Punches like this were used with a hammer to pound out bolts or rivets whose heads had been cut off.

This tool is part of a collection of hand tools used in the inspection and repair of steam locomotives in Salisbury, North Carolina from the early- to the mid-20th century, roughly 1900-1955. Light repairs on steam locomotives were usually done in roundhouses at the many small locomotive terminals throughout a railroad's system; heavy repairs were done in a large, centralized repair shop serving the whole system (often referred to as the "Back Shop").
