In June 1954 "Rail" was ordered to Coco Solo, Canal Zone, and placed under operational control of the Commandant, 15th Naval District. On 7 February 1955, she was reclassified as a coastal minehunter (MHC-37). She operated out of Coco Solo and Guantanamo Bay, putting into Norfolk briefly on 11 June 1956. She returned to Coco Solo, where she remained until sailing north to Boston on 4 September 1957.
