Water Tube Boilers
2013-4-3u2002·u2002128 forum posts. 46 photos. I am currently reading a book called 'Model Locomotive and Marine Boilers' by Martin Evans. A chapter towards the back of the book shows a very simple 'water tube' gas fired design for a 2 1/2' gauge locomotive and the book suggests that similar designs could be applied to larger scales - say 3 1/2' gauge.
