As a nation-state, Germany did not come into being until the creation of the German Empire in 1871 from the various German-speaking states such as Prussia, Bavaria, Saxony, Baden and Württemberg. By then each of the major states had formed its own state railway and these continued to remain...

; its dimensions, heating area and grate area being almost the same, only the driving wheel diameter being larger. It was built in two series.

Series 1 delivered 57 locomotives in four batches which had a boiler

 of 8 bar. The first two batches, delivered in 1863 and 1864, had a large goblet-shaped smokestack and open driver's platform with a windshield. Batches 3 and 4, delivered from 1865 - 1867 added a roof over the driver's platform; the smokestacks were now cylindrical or pear-shaped and an injector and pump for the feedwater.

On the second series of five batches, the boiler overpressure was raised to 10 bar. The first two batches (delivered 1867 - 1869), unusually, were peat-fired and hauled a covered peat tender. The first batch had side windows on the driver's cab and cylindrical or funnel-shaped chimneys. The second batch (see illustration of ORLANDO DI LASSO) lost the side windows again. Batches three and four, delivered in 1870, were a mix of peat-fired engines with funnel smokestacks and coal-fired engines with conical chimneys. The final batch of 6 engines, delivered in 1871, were peat-fired with funnel smokestacks and no side windows and rounded corners to the cabs.

The last two examples remaining in service (422 WREDE and 432 MARKTL) were transferred to the ownership of the Reichsbahn

They were coupled to Bavarian 3 T 9 and 3 T 9.6 tenders
Tender locomotive
A tender or coal-car is a special rail vehicle hauled by a steam locomotive containing the locomotive's fuel and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so tenders are necessary to keep the locomotive running over long distances. A locomotive...
