I get all sorts of e-mail from different places. This little tidbit was in an e-mail from Atlas Obsucra: https://www.atlasobscura.com/articles/what-did-railway-surgeons-do. My maternal grandfather was listed as a railroad carman in some records. I never figured out which railroad(s) he worked.
Here’s a link that’s a great reference site for railway surgeons and surgery, and it can be found in the link above, http://railwaysurgery.org/. It’s an interesting read. Found the surgeons developed hospital railway cars that were the basis for those used during World War II.
Here is another link from the first link above, where a man was hit by two trains in three weeks and lived: http://www.railwayaccidents.port.ac.uk/two-accidents-too-many-multiple-cases-1/.
