Tenders
The G 12 was mainly equipped with Prussian class 3 T 20 or 2'2' T 31.5 tenders. The Saxon XIII H, on the other hand, generally ran with the somewhat larger Saxon class 3 T 21 tenders, resulting in a greater overall length. Because water tank volume was reduced on conversion to coal dust firing, only large Prussian 2'2' T 31.5 tenders or standard tenders were used after the war.
