That answer is cool but now there are 2 seasons of Toaru Kagaku No Railgun and that probably was answered before the second season appeared, since it doesnt seem to make a reference to it

**A Google search would actually get you several timelines for the series**, one of which is shown below:
[![enter image description here](https://i.sstatic.net/9Yimj.jpg)](https://i.sstatic.net/9Yimj.jpg)

Here, you can see there is an overlap to the events that occurred in 'Toaru Majutsu No Index' and 'Toaru Kagaku No Railgun'.

Here's an even more specific timeline and it *clearly* shows which episodes and arcs these overlaps happen:
