Last year there was video of a newly restored EFDTC 2-6-6-2 in steam. It's not on the DTC, but a different preserved line. Any updates on her status?

The EFDTC 204, 2-6-6-2, to which you refer is located at Trem da Serra do Mar, which operates regular steam-powered excursions between Rio Negrinho and Rio Natal, Santa Catarina, Brazil.

In November, 2009, during a visit to Rio Negrinho, the following notes were recorded:

"Seven steam locomotives exist at Rio Negrinho, site of a museum. Several locomotives are serviceable:
• ABPF 155, 2-8-2 (ALCO 69447 / 1941), originally EF Dona Tereza Cristina, meter gauge, wood-burner
• No. 311, 4-6-0 (Lima 1292 / 1913), meter gauge, nee-EF Sorocabana
• ABPF 760, 2-8-2 (BLW 72209 / 1945), originally EF Dona Tereza Cristina, meter gauge, wood-burner

From “Inventário:” In 2005, the following locomotives are stored at Rio Negrinho:
• No. 627, 2-8-2 (BLW 58350 / 1925), meter gauge, ex-Rede de Viação Paraná-Santa Catarina
• No. 770, 2-8-2 (BLW 73077 / 1946), meter gauge, nee- Companhia Mogiana de Estradas de Ferro
• No. 204, 2-6+6-2 (BLW 74647 / 1949), meter gauge, ex-EF Dona Tereza Cristina
• No. 206-5M, 2-10-2 (Skoda 1982 / 1949), meter gauge, ex-EF Dona Tereza Cristina"

From Thor Windbergs (in 2009): “No. 204 is under repair at Rio Negrinho. The boiler has been re-flued and steam tested and at least the front engine unit was run on steam. I think the big problem is that the tender is rusted through.”

On December 29, 2013, Rafael Bordini Monteiro wrote, "The ABPF are working on 204 Mallet."

Here is 205 recently cosmetically restored in Tubarao.
