The sentence describes two events: 1) She reached the station, and 2) The train left. This suggests that the events followed each other in immediate succession.
"Scarcely" is used with "when," not "than." "Than" is typically used for comparisons, thus incorrect in this structure.
The sentence must follow the structure "Scarcely had [subject] [past participle]... when [simple past]."
Though "when" is correct, the verb tense "was leaving" does not match the immediate action suggested by "scarcely." It should be in simple past tense.
Using "than" is incorrect for this structure.
The word order is incorrect; it should be "Scarcely had she reached" for proper inversion.
This follows the correct structure "Scarcely had [she] [reached]... when [the train left]."
