Well the only things Touma couldn't stop at all would be those weird objects from a different dimension the 2nd princess of England summoned, so what would be the difference between Misaka's Railgun and those giant objects? Maybe Touma's power can negate powers and objects or energy created unnaturally. The giant objects from the different dimension weren't created by her power, but already existed in their own dimension and she just allowed them into this dimension. Misaka's Railgun is completely powered by her powers, so IB negates it. If there are other times where Touma couldn't negate something created by unnatural cause, then this is all obsolete.
