Re: N.G 2-10-2

El Senor Coke,
I believe you're correct on both counts.
The line in southern Patagonia, near Tierra del Fuego is the Rio Turbio. I understand the steamers (Mitsubishi - I think and circa 1950 or so) have been replaced by diesels but are still on the property and the report is that at least one may be used for tourist service. Tractive effort is about equal to a K-27 - not bad for a 30" gauge lokie. The late lamented L&RP ran a great article on this line some years ago. More current info may be found in Rob Dickinson's international steam pages.
The line with the 2-10-4s is the Dona Teresa Cristina in southwestern Brazil. The line also had 2-10-2s, 2-8-2s, and 2-6-6-2s, which I understand are still on the property and maybe used for special events. "Trains" ran an article on this line some years back and Sunday River may still be selling a good video on the line. Its really like watching the EBT with Santa Fe and Texas types running full bore pulling long strings of coal cars (they're not exactly hoppers). There are also good video segments on the Mikes and Articulateds. The Articulateds were mentioned by another poster several months ago (maybe even you). They're kind of high-waisted and look to be a bit lighter than the Uintah engines. But in this day and age, how many color films are you going to see of active, n.g. Baldwin 2-6-6-2s.
I've also seen photos of other ng 2-10-2, but can't recall where.
Best Regards, Glenn
