The StEG I 476-487 were Engerth locomotives of the Staats-Eisenbahn-Gesellschaft (StEG), a private Austrian-Hungarian railway company .
The twelve machines belonged to a larger number of Engerth locomotives of the StEG, which were procured from different manufacturers and therefore differed more or less from each other. The vehicles discussed here were supplied by the Esslingen machine factory in 1857. In the first designation scheme of the StEG they were given the numbers 476-487 and the names SMICHOV , WRSCHOWITZ , REICHSTADT , PÜRGLITZ , FRIEDLAND , BÖHMERWALD , ST. IVAN , MÜNCHENGRÄTZ , ZÖPTAU , SCHRECKENSTEIN , LÁMRSK and WITTINGAU . In 1858 Esslingen built two more identical machines, to which the StEG assigned the numbers 492–493 and the names HRADSCHIN and TRÜBAU .
In the designation scheme of 1873, the 14 machines were assigned the numbers 744-757 and the category IVh. In 1897 the seven remaining locomotives of the first and one of the second delivery series came as 3260–3267 in the third designation scheme of the StEG. When the StEG was nationalized in 1909, they were no longer in the locomotive inventory.
According to Mayer's dissertation, the vehicles described here were identical to those described under SStB - Nabresina to Prosecco . However, the different cylinder dimensions speak against this claim.
