The MBE 4 of the Müllheim-Badenweiler Railway was a meter-gauge, four - axle Mallet compound locomotive . It was built by the Borsig locomotive factory for Vering & Waechter and used on the Müllheim – Badenweiler line in Baden . It was in use until the line was electrified and then passed on to the Spreewaldbahn , where it was used until 1926 and then scrapped.
history
After the train loads rose sharply shortly after the opening of the Müllheim-Badenweiler Railway, the previously used MBE 1–3 could no longer meet the requirements, and Vering & Waechter ordered a Mallet compound locomotive from Borsig for heavy traffic in the summer months to be able to safely transport longer trains even on steep inclines. Due to a strike in the manufacturing company, the locomotive could not be delivered until June 2, 1898. After extensive test drives, when there was still some rework to be done on the machine and some bridge structures to be reinforced, the locomotive was first put into service as the MBE 4 .
For this, the engine shed was enlarged from three to four stands, a workshop was added and an additional water crane was installed.
In 1898 Vering & Waechter withdrew the previous number 1 , whereupon the Mallet locomotive got number 1 with a second crew.
The locomotive drove on the line until electrification. The main task was trains to the health resort Badenweiler .
The Mallet locomotive was sold to the Lübben-Cottbusser Kreisbahnen in 1914 . It was numbered 8 here. The locomotive was in operation here until 1926, when it was sold as scrap.
construction
The mallet-type locomotive offered the best conditions at the time for moving heavy trains on winding routes with a weak superstructure. It was built at the Borsig locomotive factory.
It had an axle base of only 4.95 m. The two front axles of the locomotive ran in the bogie and were driven by the low-pressure cylinders, while the two rear axles were fixed in the frame and driven by the high-pressure cylinders. The wet steam locomotive worked on the principle of the composite steam locomotive .
It had a spark arrester , a safety valve of the Ramsbotton type and two sandboxes . The Lotowski bell was on the roof, as was the steam whistle. The steam engine was controlled with flat slides with an inclined design.
