There are a few possible reasons for the confusion:
* "Strand" is a common name for train stations, and it's possible you saw a mention of a station in a behind-the-scenes article or interview.
* The film heavily features train imagery, especially the train journey to Narnia. This might lead to the association with train stations in general.
* The film's production design involved a lot of sets, some of which may have been inspired by or resembled train stations, leading to a connection being made in your mind.
It's important to note that while some scenes might have been filmed in studios or on sets that vaguely resemble train stations, there is no specific Strand Station that the film is associated with.
