First off I'm going to be critical of another man's work, something I don't care to do. But it lacks the necessary second set of cylinders for the rear drivers. While a visual distraction from the reality of engineering the real thing I can suppose this to be a compromise for O gauge's tight radius curves.
A possible solution that has some resemblance in reality would be to build one of these as a Santa Fe flexible boiler Mallet (see this link for a picture http://www.douglas-self.com/MU...lexmallet/mallet.htm
You'd have to devise a frame link, if using a pair of 2026's do some wiring to run both motors off one reverse unit to keep then synched, and devise a flexible filler at the boiler joint (perhaps a stack of washers and O rings RTV'ed together). This would result in an engine that is visually correct to the necessary engineering of a prototype while solving the problem of getting such a long wheelbase around O gauge curves. Given the size of the prototypes built in the late 19th to early 20th century these as O27's would actually be pretty close to scale O when completed.
There is a model train swap meet coming up at Lynden, Washington on October 7th I think I'll shop around for a pair of 2026's and start to tinker, like I need another project.
