14-inch railroad gun which could move from coast to coast if needed.  There were emplacements for these 14-inch railroad guns at : Fort Randolph (2 each), Fort Amador (then Fort Grant) on Culebra Island.  This picture looks like it was taken on Culebra Island. There are some great photos of this railroad gun in transit on the Panama Railroad.  My favorite is one of it going across Gamboa Bridge.  These photos will follow in another presentation that will be titled "Military Railroads on the Panama Canal Zone".
