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. |

| 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.
