Prussian EP 247 to 252

When after the series production of the EP 235 to EP 246 more locomotives of this type were needed, an order was placed with BMAG and Maffei to build six more. The previous ones had been built by LHW and Bergmann. These changed manufacturers altered some aspects of the locomotives, but hardly anything changed in terms of power and roles.

The most noticeable difference was the second hood. While the older locomotives only had a hood for the boiler on one side, the transformer on the new locomotives was above the bogie and outside of the actual locomotive body on the other side. The motor now used was slightly smaller than the old one, but it also delivered a lower hourly output. Due to the 40 cm increase in overall length, the ability to negotiate curves had to be improved. This was achieved, among other things, by increasing the lateral play of the bissel axle from 55 to 80 mm.

The locomotives were all delivered in 1924 and shortly afterwards were designated E 50 47 to E 50 52, analogous to their predecessors. In the Reichsbahn, they suffered the same fate as the E 50 36 to 46. After the end of the war, only two were still operational and these were stored together with the remaining locomotives in the scrapyard of the GDR Reichsbahn, since most of the overhead lines had to be dismantled and none found any use. So they were officially retired and scrapped in 1956.
