The Benguela Railway was being built from Lobito to run due east to Katanga in what was then Tanganyika to extract the copper and exploit other resources. In fulfilling the order for small tank locomotives, Hunslet marshalled its forces and produced the Don Carlos I in 16 working days from receipt of the order. The author of the LM report noted that this was not a stock locomotive and that 40 new working drawings were required.
