Thanks guys. I got some days off coming up, I’ll start looking at this in more detail and see about making an attempt at something. If I get the hang of it fairly quick, I’ll be heading off to (and find) a railway museum here for some detail on older trains. I know Korea had trains going back to 1897-1899, which I expect might have been imports at that time as it was put together by an American, not sure how he would have gotten a heavy train over here.. I guess he could have had it built here, but not sure they would have had the technology at the time.
