Examples

Rhaetian Railway

The first Mallet engines of this type were built for the Rhaetian Railway in Switzerland. The steeply-graded metre gauge railway opened initially with conventional 2-6-0T locomotives but soon upgraded to a pair of 0-4-4-0T Mallets. Expansion to Thusis in 1896 needed more locomotives and these were the first two 0-4-4-2T Mallets, with additional water capacity in a well tank at the rear, supported by the trailing truck. The design was not entirely successful and a later batch in 1902 for the extension to reach St. Moritz were built instead as 2-4-4-0T. The earlier locos were then rebuilt to match.{{Cite book

Staatsspoorwegen class 500

0-4-4-2Ts were the first-generation Mallets used by Indonesia since the colonial period in late 19th to early 20th century, when Staatsspoorwegen (the state railway company of the Dutch East Indies) ordered 12 units from Hartmann and 4 from Schwartzkopff in 1899–1908, classified as (501–516) for use on mountain lines in West Java. These locomotives worked mixed trains that transported plantation crops and passengers on the Buitenzorg–Bandung line which opened in 1884.{{Cite book

The SS Class 500 was 10.5 m long with 1050 mm diameter wheels and a weight of 44.1 MT. It had a maximum speed of 50 km/h. During Japanese occupation in 1942, these locomotives were renumbered to BB10 and used on Saketi–Bayah railway construction which was used as Japanese war effort for coal transport to the southern coast of West Java as from coal mining in Cikotok.{{Cite book |trans-title=Railways in Indonesia.
