The SB old 29 were steam locomotives of the Südbahngesellschaft (SB), a private Austrian-Hungarian railway company .
The two locomotives were named "L'Apennin" and "Le Rubicon". These names suggest that they were originally ordered from Köchlin by LVCI for the Bologna - Florence route , but were taken over by SB. The route Bologna-Florence led across the Apennines .
The SB tested the two machines on the Semmering Railway and handed them over to the Venetian network in 1863. Since the SB did not order any such locomotives, it seems that the SB was not satisfied with the results of the tests. In contrast, the LVCI ordered a further eight (RM 4003-4010) such machines from Köchlin by 1866, with the 4009 and 4010 only having two-axle tenders. Köchlin built another ten very similar vehicles with two-axle tenders in 1871 for the SFAI (RM 4011-4020). The dimensions of the locomotives with two-axle tenders are given in brackets in the table.
The locomotives were four-coupled Beugniot support tender locomotives with an inner frame. At that time, Édouard Beugniot was chief engineer at Köchlin and developed his system to make the locomotives easier to turn. Before the two locomotives discussed here, Köchlin had already delivered two such machines to the Paris-Lyon-Mediterranean Railway (PLM) in 1859 .
The ten identical machines came from the LVCI to the Rete Mediterranea , which converted some or all of the support tender locomotives into standard four-couplers. It is not known whether the former self-service machines were also converted. In any case, they were no longer among the locomotives that came to the FS in 1905 .
