This way the keywords give information to the photo

The keywords are sorted by letters prior to every single keyword. First the cathegory of the keyword is explained, f.e. "A - Station". This means: The A-Keyword shows the next station where the picture was taken. Then there may follow "A Lillehammer" when the picture was taken in Lillehammer. Or there are two different stations mentioned, if the photo was taken between these stations. That's important to know: Each keyword with "-" behind the pre-letter(s) explains what the following keywords using that pre-letter mean. These explanations are in german, because my whole keyword system is in german language. But here you get an explaining translation:
