The D 3/3 were steam locomotives with a tender of the Gotthard Railway Company (GB), which were delivered in four series from 1874 to 1895. At the SBB , the locomotives were given the numbers 3441–3483.
First series No. 41–46
For the transportation of freight trains on the Ticino valley railways, the Gotthard Railway Company initially procured six 3/3 coupled locomotives with two-axle tender . Numbers 41–44 were supplied by the Krauss & Cie. Locomotive factory. in Munich, numbers 45 and 46 came from the mechanical engineering company Karlsruhe . The machines corresponded to the locomotives of the Bourbonnais type built at the same time by Koechlin in Mühlhausen for the Ouest Suisse , the Jura Bernois and the Swiss Central Railway , but were somewhat heavier and stronger.
Replica series No. 51–83
For the mountain routes on the Gotthard and Monte Ceneri , which were opened in 1882, a second, stronger series D 3/3 was ordered from the Esslingen machine factory . They largely corresponded to the Mogul tank locomotives Ec 3/4 81-92 built at the same time in Esslingen and Winterthur . The boiler and engine dimensions of both vehicles were identical, so that common spare parts could be used.
From 1890 to 1895, the Swiss Locomotive and Machine Factory (SLM) in Winterthur supplied two further replica series with the numbers 67–83, which had been reinforced again compared to the Esslingen machines.
Modification of No. 83
Locomotive no. 83 was equipped in 1906 with new cylinders, Lentz valve control and a Pielock steam dryer system built into the boiler .
