FROE 11, 12, and 13 are JNR Class C12 locomotives that were bought from the Japanese railways by their original owners, the Great Southern Railway of Eruowood City and Porta Changa. They were fitted with wider tires (locomotive driving wheels had iron tires which were heated to expand them, then driven over the wheels so that they shrank into place. By fitting wider tires with a deeper tread width, the effective wheel gauge could be decreased from the Japanese standard of 3 ft 6 in (1,067 mm) to 4 ft 8 1⁄2 in (1,435 mm). They were then "Americanized" and put into service.
