I thought that I'd post some of my collection of Brazilian narrow gauge (meter) locomotives. Some of these are pretty large, including their 2-6-6-2 and even a 2-10-4! Can you imagine being a fireman on a wood burning 2-10-4? While not 30", I think that there could be some freelance ideas here.
It's not a fancy site, just the scans posted. Go to the directory here:

I have to say when you watch the videos of the 2-6-6-2's a 2-10-4's on youtube, you tend to catch a bug and want a narrow gauged chunky 2-10-4 :o

For some bigtime 30Inch gauge, take a look at the Rio Turbio's 2-10 2s
