The Class HD300 (HD300形^?) is a hybrid diesel/battery Bo-Bo wheel arrangement shunting locomotive type operated by JR Freight in Japan.^[1] The prototype locomotive, HD300-901, was delivered from the Toshiba factory in Fuchū, Tokyo to Tokyo Freight Terminal on 30 March 2010.^[2]

Design

The new locomotive uses lithium ion batteries, and is 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.^[3]

Externally, the locomotive is finished in a bright red livery to aid visibility, with yellow and black diagonal warning stripes at the ends.^[1][4]

History

The prototype locomotive was delivered 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.^[4] The locomotive was moved to Sapporo Freight Terminal in Hokkaido in January 2011 to assess battery performance and adhesion in cold winter conditions.^[5]

The prototype locomotive entered revenue service from 11 July 2011, on shunting operations at Tokyo Freight Terminal. One full-production locomotive is scheduled to be delivered during fiscal 2011, also for use at Tokyo Freight Terminal.^[3]
