A portion of the locomotives will be assembled in kit form by China's own Dalian Locomotive Works. These units were reportedly capable of meeting the EPA's strict regulations and began delivery in the latter half of 2007. Due to reliability issues, FMG units 910 to 917 are stored and deemed not be used. They were purchased to be used as "slave" units, and they were more offline than they were in use.
