The SEG 103 of the Süddeutsche Eisenbahn-Gesellschaft was a meter-gauge, four - axle mallet composite locomotive . It ran from 1896 to 1955 on the Zell – Todtnau line and on the Mittelbadische Eisenbahn lines until 1959 , when it was retired and scrapped.
history
After the SEG 73 and 74 from the early days of the Zell – Todtnau railway line were no longer able to cope with the increased traffic, the SEG 103 was procured in 1896 by the Alsatian mechanical engineering company Grafenstaden . It was primarily used in freight train service.
The performance of the locomotive was not ideal due to the unfavorable high-pressure / low-pressure cylinder ratio, but the locomotive was characterized by its economy. In addition to freight trains, the locomotive also carried GmP trains. Even after the delivery of the SEG 105 and SEG 104 , the locomotive was indispensable in operation for many years and could only be replaced in the 1950s, after the decline in freight traffic. The locomotive was moved to the Schwarzach depot within the Mittelbadische Eisenbahn in 1955 . There the locomotive carried a daily passenger train and freight trains on the MEG main network. B. to Söllingen airfield . After purchasing a diesel locomotive, the locomotive was retired in 1959 and scrapped in 1960.
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 as a one-off by the Elsässische Maschinenbau-Gesellschaft Grafenstaden and had a compact design with an axle base of just 4 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 . In 1950 it was retrofitted with electric lighting, a new steam whistle and modern automatic oiling.
