The locomotives of type T 4 II were wet steam tank locomotives of the Palatinate Railways , which were transferred to the Royal Bavarian State Railways from 1906 as the management on the left bank of the Rhine.
They were largely identical in construction to the D XI series from Bavaria, but six millimeters longer than the latter and, at 39.6 tons, heavier. Grate surface, firebox heating surface and the diameter of running and coupling wheels slightly reduced. The rear coupling axle was stored with the trailing axle in a Krauss-Helmholtz steering frame, and the storage container for the coal was behind the driver's cab . The locomotives were able to pull a 400 ton train on the plain at 45 km / h.
The three built copies had the track numbers 257 to 259 and the names "Ulmet", "Eschenau" and "Erdesbach". In 1925, the Deutsche Reichsbahn took over all three machines as class 98 4 with the numbers 98 401–403. Until their retirement in 1933/34, the locomotives were at the Landau depot .
