   I think Ive got it now--non of the pictures were convincing that there   
   was enough clearance under the boiler-cab frame for the drivers to   
   swing, but I guess those drivers must be close to being under the pivot   
   so they won't swing as far away from the center line as I was imagining.   
      
   One remaining question, or maybe two--why are the cylinders as far away   
   from the boiler as they can be? Do the exhausts lead back to the smoke   
   stack?   
      
   That is a lot of high-pressure steam hose!
