Data from "Garratt Locomotive for the Congo Railway", Locomotive Magazine, Volume 19 (15 October 1915), pp. 225; and A[rthur] E[dward] Durrant, Garratt Locomotives of the World (revised edition) (Newton Abbott, UK: David & Charles, 1981), p 150. Works number was 1744.
This was the first entry Locobase created for this single locomotive (in 2000); in this configuration the engine embodied all the features of a typical Garratt such as the Belpaire firebox and plate frames.The original, now described in Locobase 20113, did not have a superheater and had Serve tubes with nearly a inch greater diameter.

They offered several variations on the basic Garratt design. One was the installation of large-diameter, internally finned Serve tubes. Another was an unusual arrangement for fuel burning: "Under the principal [round-top] boiler shell are two smaller cylindrical drums with fire tubes inside."
What appears to be a later superheated makeover of this locomotive appears in Locobase 937.
Data from A[rthur] E[dward] Durrant, Garratt Locomotives of the World (revised edition) (Newton Abbott, UK: David & Charles, 1981), p.152. Works numbers were 1901-1912 in 1919, 2001-2009 in 1924, and 2040-2049 in 1926.
Double six-coupled Garratts from a Belgian firm to a Belgian colony. Those delivered in 1919 and 1924 burned coal. The last ten arrived as oil-burners with a bunker capacity of 312 Imp gall 1,420 litres). They weighed five short tons more at 130,928 lb (54,850 kg). .
These followed the Congo River from the port of Matadi to Leopoldville.
