The artisans for the industry are educated in the Namibian Institute of Mining and Technology (NIMT) in Arandis, Keetmanshoop, and Tsumeb.
The locomotives were placed in service on the line between Lüderitzbucht and Keetmanshoop and on the lines from the latter north to Windhoek and south to Warmbad.
During his tenure there, Leutwein created a decentralized administration with three regional centers (Windhoek, Otjimbingwe and Keetmanshoop).
Aroab is only reachable on land via gravel road - the C16 170 km from Keetmanshoop and 35 km from Klein Menasse / Rietfontein borderpost, the C11 182 km from Karasburg and 142 km from Koës.
Apart from Windhoek, the Pupkewitz group has outlets in many other places in Namibia, among them Walvis Bay, Keetmanshoop, Grootfontein, Otjiwarongo, Gobabis, and Aranos.
