D19Er

The D19Er, also called the Hữu Nghị locomotive, is a small class of five diesel locomotives used by Vietnam Railways, mostly on the northern part of the Vietnamese network. They were built in 2006 by CRRC Ziyang in China, the Sichuan locomotive works that was formerly part of CSR, and the infobox of the article gives the builder model as SDD3. They are standard-gauge machines of 1,435 millimetres with a Co'Co' wheel arrangement, a weight of about 108 tonnes and a top speed of 120 kilometres per hour, and they haul both passenger and freight trains, including on the rail link that now connects Vietnam with Europe. On 5 October 2022 locomotive D19Er-2035 derailed with two freight cars near Na Phuoc village in Chi Lăng district on the run from Lạng Sơn to Hanoi, with no damage to people or goods.
