The 39 class 80 standard design locomotives with the characteristic "snub nose" were built in 1927/28 for switching work in passenger yards and for work on short routes. After the war they were employed in both parts of Germany well into the 1960s. Several particularly durable, used units were then sold to private companies and used for years in industrial work.
