Looks like fun. I'm ashamed to say 30 years ago I did the tourist thing of riding the converted sugarcane RR on Maui, but at least there was a glimpse of "the old ways". Besides, it was the only RR action in the state. Beggars can't be choosers.
I've been fascinated off and on by the current NG sugarcane operations in Australia. Search YouTube for "australian sugar cane railway" and there are lots of great vids.
