Just to jump in here late on the discussion, I can see both sides of the issue. I like the idea of steam remaining in its natural habitat so to speak, and if the countries can restore the stuff thats the best solution. But on the other hand where there is little money for preservation, and the equipment will be worse-off for staying, then perhaps the foreign buyers are welcomed.
One thing I notice with steam fans, and railfans alike. They are very provincial. That is to say that most of us only like what we are familiar with, or have witnessed. If you've been to South Africa you are passionate about their steam, or if you have seen Guatamala then you are passionate about that. Others who have have not been to these places generally are not interested. Thats just the way it seems to be.
This discussion made me recall a situation where the NdeM owned some 4-8-4's In Mexico and some Americans tried to buy them. They were considered National Treasures by the Government, and were either not allowed to be sold or the price was extrordinarily high so that nobody would buy them. I think the engines remain in a scrap yard north of Mexico City!!!
