The locomotives of the genus VIII d of Großherzoglich Baden State Railways were freight tank locomotives the wheel arrangement D with a Hagans engine. The locomotives delivered in 1900 were not a successful design.
history
The Baden State Railways needed locomotives with good cornering behavior for the mountain routes. The mallet locomotives of the class VIII c could not satisfy due to the articulated steam lines and the driving characteristics. For this reason, two locomotives with the engine developed by Hagans were ordered from Henschel . The power is transmitted from a fixed group of drives to axes mounted in a movable frame using rocker arms. Similar locomotives were delivered to the Prussian State Railways as the T 13 .
The power transmission to the rear axle group by means of a rocker arm required a lot of maintenance. In the meantime, successful designs of laterally movable running and coupling axles were also available. Thus, the construction of locomotives with Hagans engines was not pursued. As a fragment type, the locomotives were retired after a short period of operation.
Constructive features
The locomotives had a sheet metal frame with a water box in between. The riveted long shell consisted of two shots. The steam dome with valve regulator sat on the rear boiler section. The boiler was fed by two steam jet pumps.
The horizontally arranged two-cylinder wet steam engine was designed as a Hagans engine. The engine worked on the rear axle of the front wheelset group. The power transmission to the rear wheel set group was carried out by means of a rocker arm. The Heusinger control was external and had flat slide valves.
The two front wheelsets were fixed and the two rear wheels were moveable. The suspension was provided by leaf springs below. Balance levers were located between the springs of the front and rear axle groups. The Westinghouse air brake worked on all wheelsets from the front. The sand container was on the front boiler section. The first axle was sent when driving forwards and the second when driving backwards. The coal containers were behind the cab as well as in front of it.
