The '''Saxon Class VIb <math>\textstyle \mathfrak{V}</math>''' were four-coupled, tender locomotives in [[express train]] service with the [[Royal Saxon State Railways]]. In 1925, the [[Deutsche Reichsbahn]] grouped these engines into '''DRG Class 34.8'''.

== History ==
The Saxon Class VIb V locomotives were built from 1889 onwards in a total of 14 units by the [[Sächsische Maschinenfabrik|Hartmann]] and were designed for hauling express trains. They were mostly retired by 1922. The Reichsbahn took over just one engine and gave it the running number 34 8011. It was retired in 1925.

== Technical features ==
These locomotives were the first [[compound locomotive]]s in Saxony. Its two-[[cylinder (locomotive)|cylinder]], compound engine was located behind the [[carrying axle]] and drove the final axle. The locomotives had an inside [[Allan valve gear]]. The [[steam dome]] was in the centre of the [[boiler]] over the middle axle. The [[running gear]] had an improved ''Nowotny'' carrying axle, nevertheless it did not have good riding qualities. The ''Schleifer'' brakes were later converted to [[Westinghouse brake]]s.
