Electric Locomotives, Panama Canal, MG_5854

Also referred to as “Mules”, those locomotives hold the ship with strong cables as show here.(barely in the picture)  Mules were operated on rails parallel to the canal, with one or more on each side to control and center the movement of the ocean-going vessels.


A special electrical connection enabled motors to operate at 1 mile per hour when towing larger ships.


This locomotive waits for the next arriving ship, and depending on the size of the vessel up to 8 mules can be used to control the movement thus avoiding disaster.
