In which place of the timeline of Toaru Majutsu no Index series does the Toaru Kagaku No Railgun series happen?


In the timeline of Toaru Majutsu No Index (no the release dates of the
series/ovas/specials etc which is a completely different thing) where do the
Toaru Kagaku No Railgun series happen?




**A Google search would actually get you several timelines for the series** ,
one of which is shown below: [![enter image description

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: [![enter image description

Other timelines are more or less similar.
