These engines were the first six-coupled vehicles in Bavaria with external frames. In addition they had Stephenson valve gear and, because the final axle was driven, a very long connecting rod with a Hall crank (Hallscher Kurbel). Because of its large wheel diameter, it could also be used to haul passenger trains.

The locomotives were equipped with 3 T 9 tenders.
