    German steam locomotive classes 97

    Author: John Oxlade, Salfords, England (email: )


    Most of the information outlined below was gleaned from the series of books Eisenbahn-Fahrzeug-Archiv, Dampflokomotiven deutscher Eisenbahn, published by alba.

    In the table below, the link to the image will be in the column appropriate to the version.
    i.e. If it's in it's original form, it'll be in the Origin and class column.
    If it's running with a DRG or DB number, it'll be in the DRG/DB column.
    If it's a DB rebuilt version, then it will be DB rebuilt that's highlighted.

    Zahnradlokomotiven - Rack (and pinion) locomotives

    DRG/DB Class and sub-class Origin and class Type Built
    970 Prussian T26 2-cylinder 2-6-0 with supplementary 2-cylinder engine for the Abt System rack drive. 1902
    971 Bavarian PtzL 3/4 2-cylinder 2-6-0 with supplementary 2-cylinder engine for the Strub system rack drive which together acted as a 4-cylinder compound when operating on the rack drive. 1912
    972 Baden IX b1
    Baden IX b2
    2-cylinder 2-6-0 with supplementary 2-cylinder engine for the Riggenbach system rack drive which together acted as a 4-cylinder compound when operating on the rack drive. 1910
    1921
    973 Wurttemberg Fz 2-cylinder 2-6-0 with supplementary 2-cylinder engine for the Riggenbach system rack drive which together acted as a 4-cylinder compound when operating on the rack drive.
    See note below for 975.
    1893
    974 Prussian T28 2-cylinder 2-8-2 with supplementary 2-cylinder engine for the Abt System rack drive which together acted as a 4-cylinder compound when operating on the rack drive. 1921
    975 DRG New design, planned originally to be a Wurttemberg Hz, but the DRG was formed before the order was placed 2-cylinder 0-10-0 with supplementary 2-cylinder engine for the Riggenbach system rack drive which together acted as a 4-cylinder compound when operating on the rack drive.

    Note: The rack railways of Wurttemberg used the Bissinger-Klose variation of the Riggenbach System. This consisted of large trapezoidal teeth cut from a solid bar, rather than a fabricated 'ladder'.
    Although 97 501 was on display at Obernzell (in Bavaria, the home of the 971's), as far as I know, it was only on display, it never ran there - the rack systems were not compatible.

    1923
