Background:
The checkAndChangeStationIntType function currently does not modify the interchange property of transfer stations with context-appropriate information.

Task:
Update checkAndChangeStationIntType so that it adaptively sets the interchange attribute of transfer stations, providing suitable interchange details based on the station context.

Expected Outcome:

• The interchange property should be automatically updated when detecting a transfer station in checkAndChangeStationIntType.
• The property should accurately reflect the correct interchange information.
• The change should not introduce regressions elsewhere.

Notes:

• Ensure robust testing around this updated functionality.
