Abstract: A portable electric railroad rail drill apparatus includes an elongated main shaft, a support frame, an electric drill, a clamp, a handle and a support leg. The support frame is reciprocally mounted to the main shaft for movement therealong between first and second ends of the main shaft. The electric drill is fixedly mounted to the support frame and reciprocally movable therewith along the main shaft. The clamp is mounted at a location adjacent to the first end of the main shaft for mounting the main shaft to a railroad track rail such that the electric drill is disposed adjacent to the rail and movable along the main shaft toward and away from the rail and is operable for drilling a hole through the rail concurrently with movement toward the rail. The handle is pivotally mounted to the main shaft and pivotally coupled to the support frame and extends upwardly therefrom such that the handle can be pivotally moved between forward and rearward positions to cause movement of the support frame along the main shaft and thereby the electric drill toward and away from the rail for drilling the hole through the rail and removing the electric drill from the hole. The support leg is mounted to the second end of the main shaft and extends in a substantially transverse relation thereto such that the support leg rests on the ground and supports and retains the second end of the main shaft above the ground.
