In the last phase of steam locomotive development in Bavaria, the locomotive fleet was modernized in terms of performance and economy. Particularly tried and tested locomotive types were also reproduced after the establishment of the Unification Committee (narrow committee for locomotives for the unification of locomotives) in 1921, including the P 3/5.
After the founding of the Deutsche Reichsbahn whose group management commissioned Bayern the company Maffei with the construction of eighty steam locomotives of the Bavarian type P 3.5 H . These machines were based on the type P 3/5 N ; Frame and drive were taken over unchanged, the boiler was enlarged a little and got a superheater . The cylinders were each enlarged by 20 mm in diameter. The driver's cab was also made larger.
The good experience with these vehicles built in 1921 - they were even used in express train service - led in 1924 to the conversion of all existing P 3/5 N vehicles to superheated steam locomotives.
In 1925 the P 3/5 H with the numbers 38 401 to 38 480 were assigned to the 38.4 series.
All eighty locomotives survived the Second World War and came to the Deutsche Bundesbahn . The last machine of this series, the 38 432, drove in Bavaria and Upper Swabia and was decommissioned in 1955.
The vehicles were traveling with a Tender of the type bay 2'2 'T 21.8 coupled.
