Spoiler for Railgun manga:

Realistically? Impossible. But laws of anime don't work the same way as the laws of physics do. It's like how Mikoto manages to fire a railgun blast completely ignoring the heat and recoil produced, it's cooler just to ignore these little details.

second, i get that touma is able to counter anything magic and scientific, but the 'scientific' part of railgun's attack is the actual acceleration, so him being able to stop an attack is no more different than stopping a bullet from a gun (which i think he can't do). can someone explain this? iirc railgun likes to accelerate coins as an attack too

Spoiler for Railgun manga:

The occurrence of Touma blocking a railgun is actually a heated debate that never really reached a conclusion, as some consider the Railgun manga event to be a non-canon occurrence. Regardless on the canonical possibility, we don't know exactly how it works.

However, we've never really reached a conclusive decision on this. Should the anime have Touma do the same, I'd say that would make it more likely to be true.
If you are willing to spend a bit of time reading, this thread has a rather lengthy debate on it.
