BR 13.15 / BR 13.71

The first express train locomotives of the Saxonian railways was the VIII 2 (BR 13.70). This steam engine, built by Hartmann was satisfying only for a couple of years. They decided in 1896 to introduce the compound system in express train locomotives. From 1896 Hartmann delivered 32 2'B n2v express train locomotives of type VIII V1. After the first series in 1896 a second series followed in 1897 with 10 locomotives and in 1900 a third series followed with the last 12 locomotives. The locomotives of the third series were a little more powerful than the previous two series.

The third series had a boiler pressure of 13 bar (1th and 2th had 12 bar boiler pressure). The roof of the drivers cab was longer and ran a little over the tender. The first two series (nr 121 up to 130 and 131 up to 140) were coupled with a tender sä 3T12, the third series had a tender of type sä 3T 15. The locomotives were able to pull a train of 210 ton on flatland with a speed of 90 km/h, and a train of 180 ton on a hillside of 5‰ with 70 km/h.

The DRG took over 11 steam engines of the third series and put them into service under the numbers: 13 1501 up to 13 1511. From the first and second series, 12 steam engine were going to the DRG and they got the numbers: 13 7101 up to 13 7112.
