The Prussian T 37's were German steam locomotives operated by the Prussian state railways. They replaced the smaller 0-6-0T locomotives on the railway line between Beuthen and Kattowitz. In all 18 engines were supplied to Prussia, of which eight were taken over by the Reichsbahn and given numbers 99 401 to 99 408. They were all withdrawn by 1939 and scrapped.
These locomotives were equipped with Klien-Lindner axles at each end. They had an outside frame and the third wheelset was driven. They also had an outside Walschaerts valve gear. The engines could carry 1.3 tonnes of coal and 2.5 m² of water. The coal tank was located behind the driver's cab.
