Data from "3/3 gek. Tender-lokomotiven Altdamm-Kolberger Eisenbahn", Locomotiven, A Borsig (Tegel bei Berlin, 1898), archived on Historical Railway Images, Flickr, at [], last accessed 8 July 2022, supplemented by Albert Gieseler, "Baureihe 89.72" on his Dampfmaschinen und Lokomotiven website at [

Beginning in 1880, a consortium of the Prussian state, several districts and towns, and private interests funded the construction of a line between the Altdamm junction of the Stetttin Stargard main line and the seacoast time of Colberger (Kolberger by 1899) some 122 km distant.
The need for the line seems to have been met in shortening the route between them by 50 km (31 miles). Principal traffic included livestock and agricultural products as well as passenger service.
This standard-gauge railway continued to grow until its various branches and extensions totalled 179 km (111 miles) by 1899. By that time, the ACE had purchased this three-engine class of T3 six-coupled tanks, of which several dozen had already been produced by various builders. (See Locobase 1285 for comments on the affection accorded this little tank-engine design.)
The ACE's extent seems to have been sufficient to prompt shareholder Prussia to gain a majority and put the line under the Prussian State Railways in 1903.
