You will want to check with the members of the Critterslist. We have discussed in-depth the Homestake Mine Porters, and compressed air locomotives are often mentioned. Some of the members are in the process of restoring compressed air locomotives. Most of us are from the US and England, but are always glad to talk about other "critters" from all over the world. Signing up is free, just click on the "join" link at the website below. Then you can link to the photo gallery and check out some of the compressed air locomotives there, look through archived e-mails, and send and recieve new e-mails. Hope this helps!
