China Railway DFH shunting locomotives

The Dongfang Hong (Chinese: 东方红) was a type of single-cab diesel-hydraulic locomotive used on China Railways. The first DFH began trial production in 1959 at the Sifang Locomotive and Rolling Stock Works (CRRC Sifang), before entering mass production in 1966. The DFH series of diesel locomotives, includes the DFH2, DFH3, DFH4, DFH5, DFH7 and DFH21. The DFH 2,5,6,7 and 21 were shunting locomotives built from the 1970s to 1990s. The use of diesel-hydraulic shunters has fallen out of favour on the Chinese rail network, with diesel-electric locomotives being used. However, diesel-hydraulic machines continued to be produced for industrial railways – mainly the China Railways GK classes. The DFH21 class is a meter gauge version of the DFH2, and was used on the Yunnan–Vietnam Railway for both passenger and freight services; the same machines are used on the Vietnam Railways where they are known as the D10H.
