what is it?
The Oldenburg Class P 4.2 were German steam locomotives built for the Grand Duchy of Oldenburg State Railways (Großherzoglich Oldenburgische Staatseisenbahnen) between 1907 and 1909. They were based on the standard variant of the Prussian P 4.2, with small differences such as a Ranafier steam dryer and, on three examples, a Lentz valve gear, a system widely used in Oldenburg. Production began in 1907 and eight locomotives were procured up to 1909.
