The English translation of ‘stukkie wukkie’ would surely be the train is ‘stuck’?
Google translates "stukkie wukkie" as "piece of shit" or "wonky", depending on other nearby words, and "stukkie" as "broken". but neither of these words is in a dutch dictionary afaict. And google doesn't translate anything i tried to those words.
I’m not a Dane though so could be wrong.
Dutch is the language (and demonym) of the Netherlands.
Dane is the demonym for people from Denmark, where they speak the Danish language.
