Bill:  You can cold bend the track to shape. The hardest part is keeping 
the bend flat.  Use a strong bench vice and a steel pipe cheater, and 
work very slowly--a bend, once made, is more difficult to straighten and 
re-bend to a different radius.  If all you are doing is to work on a 
damaged section to return it to its original radius, be aware that the 
metal has a memory and you may find it easier to accomplish than you 
think.  Use chalklines on a concrete floor to indicate what your end 
state should be, and check your progress against the chalklines.

Avoid hammering if at all possible. Remember that beating on the metal 
deforms it , and will make it thicker or thinner, depending on the axis 
of the blows made.  Always make the metal thicker when cold working with 
a hammer--if you thin it out too much, it is very difficult to return 
the material to its original thickness.  Remember that thinning will 
also lengthen, and your bolt and screw holes will no longer line up 
properly--be careful.
