Prussian G 4.2

Production continued until 1899, but in 1903 there was an order for the East Prussian Southern Railway (Ostpreußische Südbahn, OS).

In 1920, The Deutsche Reichsbahn reallocated a G 4.2 to the Schwerin Division, where it was renumbered 406 in the Grand Duchy of Mecklenburg Friedrich-Franz Railway list.

With the nationalisation of the Brunswick State Railway Company (Braunschweigischen Landes-Eisenbahn, BLE), on 1 January 1938, four G 4.2 locomotives were added to the Reichsbahn fleet as 53 7001 to 53 7004 (second).

[4] Increasing freight traffic at the turn of the century made it necessary for the Grand Duchy of Mecklenburg Friedrich-Franz Railway (Großherzogliche Mecklenburgische Friedrich-Franz-Eisenbahn, MFFE) to purchase new locomotives.

In 1920 the Deutsche Reichsbahn transferred an additional locomotive, Berlin 3801 to Mecklenburg and renumbered it 406.

It was the MK's only tender locomotive, and as there were no turntables on the route, it had to bee driven backwards from Dreihausen.

Although the locomotive was fitted with a rear cab wall and Westinghouse brakes after World War I, it remained unpopular with crews.

[5] After a rebuilt, the locomotive continued to be unreliable – the crews nicknamed it the stubborn goat (störrischer Bock).

[5] Five locomotiven were sold to the Brunswick State Railway Company (Braunschweigische Landes-Eisenbahn-Gesellschaft, BLE) in 1922.
