German builder Bambi has many excellent creations in his Brickshelf gallery. His latest is a delightful seven stud wide steam locomotive from the Deutschen Bundesbahn: a BR64. The model has many painstaking details and I particularly like the comparison shot with a blueprint. He also includes images of the wheelset is useful as it is a hard part to get working in LEGO steam trains.
PS. Please excuse my bad pun in the title.
