The old steam train experience of the weekend reminded me of this. In the USA is the Worlds current largest steam train running. It is the 2nd largest steam train ever with a configuration of 4-6-6-4. Now there is a restoration project happening that should be done by 2018 of the Worlds largest steam train the 4-8-8-4 Big Boy. These trains were a huge help during World War 2. https://youtube/watch?v=6OgSNQOTw2U here is a 4-6-6-4 youtube clip.
