For this series am putting it as Trivia as I can't find the changes between the novel and anime, there also a manga counterpart to Index so for this series there is going to be multiple thread. This thread will not only contain Trivia but also the changes between three different version for Index and two different versions of Railgun as well as Accelerator.
Update: Do note the changes will be written under Note which will be at the end of every arc, also Railgun has some episodes that are original hence I will state if the episode is original or not. Added the whole of Index Season 1 plus 1 episode from Season 2 as that episode is link with that arc which I had stated clearly. Railgun Season 1 to be added tomorrow along with Index Season 2 if there is no delay that is.
Update 2: Added Railgun Season 1 and Index Season 2 as promised, I will added Railgun Season 2 and Index Season 3 three to four weeks from now which could be second week or third week of April. On the side note Accelerator Season 1 will air on July, hence the Trivia should be up once the series ends as it would be easier for to comply the information and post it in one shot instead of update it on weekly base or monthly base.
Update 3: Added Railgun Season 2, I will add in Index Season 3 at the end of April so look forward to it as I would give the site that I got this information sometime to get the information that I need to put it up here.

Overall Trivia
With 21 chapters published, this arc is the second longest one in the Toaru Kagaku no Railgun manga. Moreover, with 16 episodes in the Toaru Kagaku no Railgun S anime adaptation, it is the longest story arc in the animated series.
This is the first arc in the Toaru Kagaku no Railgun sidestory to intersect with the main story of Toaru Majutsu no Index.
Note:
In all versions of the story, a blimps appear to foreshadow Mikoto's involvment, the scene that plays out the most vital is the scene where Mikoto declares in front of Touma that she despises blimps. In the original novel, the Mizuho Organization is shown in the blimp to have withdrawn, during Touma and Mikoto's first meeting after his memory lost. In the scene where she meets Touma a second time after his memory lost, the narration references that three muscular dystrophy research institutes have withdrawn. This is carried over in the anime adaptation. In the manga adaptation, the scene in their first meeting is removed, though it is later shown in their second meeting, however, the Duchenne Dystrophy Research Center is the one that is referenced. This segment is removed in its entirety in the Toaru Kagaku no Railgun manga, as the audience is aware of that Mikoto is involved; although, the blimp can still be seen in some panels. Their second meeting, also redacts the blimp reporting about the research institutes, and instead focuses on the subject around Tree Diagram.
This scene is slightly modified in the Toaru Majutsu no Index manga adaptation Chapter 12. Tsuchimikado Maika does not appear in the scene, and since the Deep Blood Arc was not adapted into the manga, Aisa is not present, leaving only Index present for the scene.
The scene plays out somewhat differently in the original novels, as Touma realizes that he is unable to escape both the boxes and the oncoming Accelerator, Touma takes advantage of Accelerator's reflection and attacks him with gravel, which automatically counters Touma, ejecting gravel upon him and propelling Touma far enough to escape the falling containers.
The original novel has Touma blown away by Accelerator's use of the wind, and is later knocked unconscious as his body is thrown into a wind turbine's pillar. The anime plays this scene differently from the rest of the adaptations, hither, Accelerator already begins forming the plasma ball and actually attacks Touma with it and knocking down. Only the 37th Chapter of the Toaru Kagaku no Railgun manga keeps this scene intact, while the Toaru Majutsu no Index manga keeps the wind attack but has Touma fall down into several shipping containers instead.
It is noted that the researchers could have used Last Order to prevent the Sisters from gathering and manipulating the wind turbines, but stayed their hands as they might cause an irreversible damage to the experiment.
Chapter 21 of the Toaru Majutsu no Index manga adaptation completey redid the scene. Hither, Misaka 10032 and Misaka Mikoto meet just outside of Touma's ward, wherein Misaka 10032 later returns to the room to have Touma touch her breast again after referring to the reading of his bioelectricity. Needless to say, Mikoto becomes flustered because of this and later takes Misaka 10032 away.fter
The note section contains information from both Index Side and Railgun Side and it the only arc that crossover to the other series. As the next arc which both series had took after Index Side of the story with a couple of scenes being the same. That which be in Railgun Season 3 which is set to release somewhere this year.

Trivia

Scenes from episode episode 5, episode 6, episode 12, episode 13, and episode 14 are reused for flashback sequences during this episode.
After the dust explosion that Accelerator initiated during the fight, fires begin erupting in the switchyard. After regaining consciousness after being knocked out briefly by Touma's punch, the fires are completely gone. This may indicate that the fire has snuffed itself out after quickly consuming all the oxygen it could in the windless night.
The second time Touma punches Accelerator resembles his Finishing Move animation sequence featured in Toaru Majutsu no Index (PSP game) barring the dragon.
Episode 38 - The Promise
Major Event

Trivia
stand still returns as the ending theme for the episode, though having notable difference is that Touma and Mikoto's positions are switched.

Touma heads to Mikoto's room in the Tokiwadai dormitories located away from the main campus in an attempt to speak to her and approach her about the Level 6 Shift experiment.
Trivia
Accelerator's flashback has him killing indirectly the first Misaka clone. The scene is taken from the tankobon version of the chapter instead of the magazine version, where it implies that Accelerator killed Misaka 1 instead of her own doing.
The direction set up in a way to make it seem that Touma was close in discovering Misaka 10031 and Accelerator's battle, unlike that of the previous adaptation of the scene which shows that it has been quite a while since Misaka 10031's death and then Touma discovering the corpse.
As a coup de grace to the Misaka 10031–10032 confusion, Misaka 10032 explains in detail her and Misaka 10031's role in the story.

Touma references both Index and Himegami Aisa in her conversation with Misaka 10032 regarding taking care of cats, specifically Sphynx.
The Destruction of Tree Diagram and its Remnant is referenced during this episode.

The sound effect used upon the bullet hitting Saiai's Offense Armor is similar to the one used for when Accelerator's reflection. This is a nod to the origin of Saiai's powers from the Dark May Project.
