Currently awaiting my new model after the poor running of the 58XX I returned. I really have my fingers crossed this one will be a good runner.
I did notice how sloppy the con rods were, it surely would have been a lot simpler to gear on one axle, and let the con rods do the work they are supposed to do (as on the prototype).
I was originally going to have two of these, however I'm generally now thinking about the second one being the Railroad model coming out later this year. With a DCC chassis, repaint and the mainly trains detailing kit...it shouldn't be too shabby.
It all depends on how well this replacement runs.
