Ninety six of them were procured for service on the stub lines running from Munich into the mountains, but in reality they were stationed in many large Bavarian locomotive depots (Bahnbetriebswerke or Bw).

Two engines were transferred to the Palatinate Railway (Pfalzbahn) in 1916, the remaining 94 later joined the Deutsche Reichsbahn fleet and were incorporated as DRG Class 73.0-1 with operating numbers 73 031–124.

28 engines were taken over as 73 001–028 by the Deutsche Reichsbahn, the remaining three were handed over to the Saar Railway (Saarbahn).

The Bavarian Pt 2/5 H built in 1906 as a one-off, had shown that the use of a superheater brought no clear gains due to the low coupled axle load.

As a result, in 1907 nine similar machines with saturated steam operation were built, as the Bavarian Pt 2/5 N class.
