I may be a bit slow, though I don't think anyone else has mentioned it here.
In April 2023 Warner Brothers / HBO announced that they are making a Harry Potter TV series.
The live-action series, based on all seven books in the series published between 1997 and 2007, will become a “decade-long series produced with the same epic craft, love and care this global franchise is known for”.
The show is expected to release in 2026 , so any suggestion that Tomy are a bit late to the party with this Hogwarts Express release is maybe a little misplaced.
