The Pts 3/4 were meter-gauge tank locomotives of the Royal Bavarian State Railways for the operation of the Neuötting – Altötting steam tram . The Deutsche Reichsbahn classified the locomotives in the 99 13 series in 1925 .
history
The Bavarian Pts 3/4 was used exclusively between Neu- and Altötting. Krauss built a total of four machines in Munich . Numbers 1101, 1102 and 1103 in 1906, number 1104, however, only after the decommissioning of number 1102 in 1922. Like classic tram locomotives, they had a disguised engine, a high-lying boiler with a water box underneath, transition plates and a railing for circulation . The locomotives were intended for one-man operation.
After the takeover by the Deutsche Reichsbahn, the three remaining machines were given the new numbers 99 131 to 99 133 in 1925 .
After the line was closed in 1930, the locomotives were only used as reserve machines and were retired in 1931. Locomotive 99 133 (formerly number 1104, factory number 7986) was used again by the Kleinbahn Wallersdorf – Münchshöfen , where it was in service from 1938 until this line was closed in 1949. Then it was scrapped.
