Variants
- Class HD300-0: Standard type, entering service from February 2012
- Class HD300-500: Sub-class designed for operation in cold-climate conditions, delivered from November 2014
- Class HD300-900: Prototype locomotive delivered in March 2010
Design
The locomotives use lithium ion batteries, and are designed to reduce exhaust emissions by at least 30% to 40% and noise levels by at least 10 dB compared with existing Class DE10 diesel locomotives. Tests conducted at Tokyo Freight Terminal in June 2010 demonstrated fuel savings of 36%, NOx emission reductions of 62%, and noise level reductions of 22 dB compared with a class DE10 locomotive.{{cite web|url= http://www.jrfreight.co.jp/common/pdf/news/201107-03.pdf|script-title= ja: HD300形式ハイブリッド機関車の営業使用開始について|trans-title= Class HD300 hybrid locomotive enters revenue service|date= 13 July 2011|work= News Release|publisher= Japan Freight Railway|language= ja|access-date= 19 July 2011|archive-url= https://web.archive.org/web/20110808075513/http://www.jrfreight.co.jp/common/pdf/news/201107-03.pdf|archive-date= 8 August 2011|url-status= dead}} Externally, the locomotives are finished in a bright red livery to aid visibility, with yellow and black diagonal warning stripes at the ends.
The first full-production locomotive, HD300-1, delivered in January 2012, while broadly identical to the prototype HD300-901 locomotive, incorporates a few minor improvements, including changes to the headlamps, a wider front-end warning panel to reduce snow build-up on the steps, and larger windows in the driving cab doors to improve visibility.

The prototype locomotive, HD300-901, was delivered from the Toshiba factory in Fuchū, Tokyo to Tokyo Freight Terminal on 30 March 2010 for approximately six months of trials before being moved to Matsumoto in Nagano Prefecture later in the year to assess performance at higher altitudes.{{Cite news|script-title=ja:国内初のＨＶ機関車 ＪＲ貨物が試作車を報道陣に公開 |trans-title=JR Freight unveils prototype of Japan's first hybrid locomotive to media |newspaper=The Sankei Shimbun |location=Japan |language=ja |date=25 March 2010 |url=http://sankei.jp.msn.com/economy/business/100325/biz1003252122053-n1.htm |access-date=30 March 2010 |url-status=dead |archive-url=https://web.archive.org/web/20100329020833/http://sankei.jp.msn.com/economy/business/100325/biz1003252122053-n1.htm |archive-date=29 March 2010 }} The locomotive was moved to Sapporo Freight Terminal in Hokkaido in January 2011 to assess battery performance and adhesion in cold winter conditions.{{cite web |url= http://railf.jp/news/2011/01/26/190000.html|script-title=ja: HD300-901，札幌貨物ターミナルで寒冷地走行試験|trans-title=HD300-901 tested in cold conditions at Sapporo Freight Terminal|date= 25 January 2011|work= Japan Railfan Magazine Online|publisher= Koyusha Co., Ltd. |location= Japan|language= ja|access-date= 26 January 2011}}
