The Appenzellerbahn ( AB ) procured 1908 and 1910 each have a hot steam - Tenderlokomotive the type G 4/5 . The first locomotive was built according to SLM plans by Maschinenfabrik Esslingen , the second by Lokomotivfabrik Winterthur (SLM); they do not differ in the main dimensions. The purchase price is stated at CHF 35,000 for No. 7 and CHF 32,200 for No. 8.
Technical
There were severe technical restrictions during construction due to the route . Thus were boiler - and engine dimensions smaller than the G 4/5 of Rhätischen web. The axle pressure was limited to 8 t and the vehicles had to be able to travel a minimum radius of 84 meters. That is why the rearmost coupling axle was installed so that it could move laterally; the second coupling axle could also be moved sideways. The third coupled axle was the drive wheel . The locomotives were two-cylinder superheated steam tank locomotives with external controls . The boiler pressure of the first locomotive was only 10 Atm., But in 1902 it was 11 Atm. increase. With its output of 500 hp , it more than doubled the output of its predecessors G 3/3 and G 3/4 .
business
A G 4/5 was always used from Appenzell . It led the first morning train to Gossau and the last evening train back to Appenzell. If both machines were available, one machine began and ended in Herisau . Only one of the two machines was used in winter. The trailer load on a 38 per mille gradient was 85 tons. In 1924 the top speed was increased from 30 to 35 km / h and in 1931 to 40 km / h.
Whereabouts
The two locomotives became superfluous after the railway line was electrified in 1933 and could be sold to the Ethiopian Railway to Ethiopia in 1937 ; for this they were rebuilt at SLM. Because of the weak superstructure , the axle load had to be reduced, which was achieved by converting it to a tender locomotive . They received a new four-axle tender and the driver's cab was also adapted to the new conditions. They were given the numbers 101 and 102. How long they were there is unknown. As the successor to the diesel locomotives of the M series but was not delivered until 1950, to accept them as Ausrangierdatum earliest the 1950s.
