I'd love to see an N scale version of the GE 45 ton shunter, complete with siderods like the HO version.  

Also love to see an N scale version of those old "heavy duty flatcars" with the six-wheel trucks.  They may not have been prototypical but they looked cool. 

I was wondering if bachmann could make a run of N scale versions of the 6-axled heavy duty steel flatcars.  The only versions I could find are in HO scale. 

Here's an example:

I would gladly but several.
