There are sights like this to be seen! It's not all shot. My friend Agustin Perez Prieguez whom I have met through an e-mail exchange, is a mechanic involved in keeping a number of narrow gauge steamers alive.
I suspect that boilers would be need to be replaced, as they would not have records of approved repairs, and they would probably not be code boilers. But even locomotives that have stayed here in the US and lovingly maintained have reached the point where they need to be replaced just from age.

I've got to agree with Keith!
There seems to be a perception that the Cuban steamers are all held together with spit and bailing wire. To be sure, some of them may be - but not all of them. In fact several of the lines: Mal Tiempo, Espartaco, Rafael Freyre, and Gregorio Arlee Manalich - were known to keep their locos in pretty good operating condition. Even the others may either be restorable or useful for parts as someone else suggested.
Now are these locos well-used? Yes. Will they need boilers? Probably. Will they most likely require thorough rebuilds? Sure. But on the other hand, a rebuild will cost you about 1/3 of building the same thing new. There has to be a place where these economics will make sense.
Now does this mean you shouldn't build a #11. Of course not! I'd love to see that as much as you would! The same with replicating any other beloved two-foot locomotive. You always have the option to build whatever you think is in the best interests or your organization. But it also makes sense to have an stock of usable locomotives that are appropriate to the operation and could be used to carry the operational load in deference to some of the more "historic" pieces. That's where these locos could fill an important niche. One need look no further than the 480s on the Durango & Silverton or the Festiniog's "Blanche", "Mountaineer", and "Linda" to see the same sort of thing being done by other great preserved railways.
But don't take my word for it. Pick up a copy of the booklet 'Trains of Cuba - Steam Diesel & Electric", by Adolf Hungry Wolf. (ISBN 0-920698-46-8) It lists pretty much every steamer operating in Cuba as of 1996. I counted 76 "two-footable" locomotives. Most of these are outside frame Baldwin 2-8-0s, but there are also a few 2-6-0s. They would look at home in Maine just like #10 does. See for yourself.
