The engines had crossed Hall cranks (gekreuzte Hallschen Kurbeln), an outside frame, Gooch valve gear and a steam dome towards the front. The boilers on all the surviving engines were replaced between 1892 and 1897. In 1895 only four were still in the fleet. The last one was withdrawn around the turn of the 20th century.
