So, if I understand correctly everything you've done,
 * you've modified the code for set so it will do the same things it does now, plus it will change the "set" icon to the "set+" icon if the first parameter = "+".
 * you've created code within trainset to display the appropriate icon alongside the infobox title.

As far as I can tell, both of the above items look good. Did I miss anything?

Did you miss anything? Did you check the "What links here" page for set to see whether any other templates need modified code?
