Data from DeGolyer, Vol 78, pp. 221+. Works numbers were 58281-58283 in March 1925.
This rail line was the extension of the Estrada de Ferro Donna Thereza Christina from Tubarpo to Araranguá. It was authorized on 23 May 1917 to take advantage of a world-wide coal shortage. Construction was divided into two sections. The longer one measured 56.55 km (35.1 miles) from Tubarpo to Crici+ma and the second 35.3 km (21.9 miles) section from Crici+ma to Araranguá.
The first section opened for some traffic on 1 January 1919. Construction of the second took much longer, only opening on 18 January 1927. These three mixed-traffic Pacifics were among the smallest of metre-gauge 4-6-2s.
After long careers on the DTC, two were scrapped. The 50 was sold to the infamous Madeira Mamore in 1982.
