Overview

The Class DD200 was developed to replace ageing Class DE10 and Class DE11 diesel–hydraulic locomotives used on freight services over non-electrified lines, and also for shunting duties at freight terminals.^[3] The locomotive has a single water-cooled four-cycle V12-cylinder diesel engine, with a power output of 600 kW (800 hp).^[4]

History

Details of the Class DD200 were officially announced by JR Freight on 15 June 2017.^[3] A prototype locomotive, DD200-901, was delivered to JR Freight's Shin-Tsurumi Depot from the Kawasaki Heavy Industries factory in Kobe in late June 2017.^[5] This is scheduled to undergo testing and evaluation in shunting operations at Tokyo Freight Terminal and in main line operations in the Tokyo area to obtain data to be used in the design of the full-production locomotives.^[1]

The first full-production locomotive, DD200-1, was delivered in August 2019.^[6]
