JR Freight Class DF200

The Class DF200 (DF200形) is a Bo-Bo-Bo wheel arrangement diesel-electric locomotive type operated by the Japan Freight Railway Company (JR Freight) and the Kyushu Railway Company.

, JR Freight operates 48 Class DF200s, and JR Kyushu operates one (DF200-7000).

Background
In Hokkaido, where the proportion of electrified sections on trunk lines is low, Class DD51 has been the mainstay of freight transport since the introduction of "smokeless railways", regardless of whether electrified or non-electrified sections are used. After the creation of JR, the increase in freight transportation and the increasing speed of freight trains made DD51's traction capacity insufficient, and double heading are forced to use in that situation. Due to the harsh climate in Hokkaido, the cars also became increasingly obsolete. Therefore, to solve those questions, the DF200 was developed.

It was rewarded with Laurel_Prize in 1994.

In 2016, DF200-123 was moved from Hokkaido to Suita Depot in Osaka, where it underwent modifications and renumbering to DF200-223 before being returned to service on the Kansai Main Line in the Nagoya area. This was followed by locomotives DF200-116 and DF200-120, which were similarly modified and renumbered DF200-216 and DF200-220 respectively in 2018.
