The Class DB500 (DB500形) is a B wheel arrangement two-axle diesel-hydraulic locomotive type operated by Japan Freight Railway (JR Freight) on shunting duties in Japan since March 2017.

Overview

The Class DB500 was developed to replace ageing Class DE10 diesel-hydraulic locomotives used for shunting duties at smaller freight terminals such as Shimonoseki in Yamaguchi Prefecture. The locomotive has a single water-cooled four-cycle straight six-cylinder diesel engine, with a power output of 184 kW (247 hp), sufficient to haul 500-tonne (490-long-ton; 550-short-ton) trains.

History

The Class DB500 entered service at Shimonoseki Freight Terminal from the start of the revised timetable on 4 March 2017.

Classification

The DB500 classification for this locomotive type is explained below.

• D: Diesel locomotive
• B: Two driving axles
• 500: Diesel-hydraulic locomotive
