Baureihe 44
From 1926 to 1949, a total of 1,989 locomotives were manufactured. During World War II an austerity variant was built with simplified construction and delivery, known as Class 44ÜK (one of the so-called Übergangskriegslokomotive). This primarily used home-produced materials; components were simplified, both in manufacturing methods and design, or eliminated altogether. The most striking features of the ÜK locomotives were the omission of the smoke deflectors (that of 44,013 was standard) as well as the front side windows of the driver’s cab.
