Has Williams produced 2 car add on  sets for southern or Pullman sets?  I have a 4 car set of each i would like to expand. Have not found any reference to any 2 car 60 ft add-ons anywhere. If not produced in tbe past , might be good business opportunity got you in the future.

Are the F7 power upgrade kit instructions available on line?  I am thinking of purchasing a s set, and would like to see whats involved first.

I have looked the diagram at your current link for modifying the reverse board to always start in the forward direction.  The board in my older Pennsy F Unit does not look anything like the one in your link.  Do you have diagrams for other versions of the board ?
