Borsig delivered 3 in 1912, 2 more in 1914. Works numbers were 8281-8283 in 1912 and 9006-9008 in 1914.
Data from A E Durrant, Locomotives of Eastern Europe (New York: Augustus M Kelley, Publishers, 1966), pp. 57, 61 Works numbers were 2567-2569 in 1892.
Durrant wrote that the SPAP's traffic had increased to a point that it needed tender engines with greater capacity to pull it. So they introduced the Consolidation wheel arrangement. Durrant described the "unusual design", which placed the firebox behind the rearmost driving set but the cylinders ahead of the leading truck, "all wheels therefore being crammed together in the middle." Thetas connecting rods drove on the third coupled axle, giving "good long rods".
Linke-Hoffman delivered five (works numbers 3034-3038) in 1925 with Henschel adding three more of the same design in 1936 (works numbers 23058-23060).
