Learn Danish: Viser den der afgangstavle vores tog? - Does that departure board show our train?

Danish doesn't use helper verbs like 'do' or 'does' to form questions. Instead, you simply start the sentence with the main verb. By putting the verb viser (shows) first, it automatically becomes a yes/no question: 'Shows that departure board our train?'

Why is it 'den der afgangstavle' instead of adding the definite ending to the noun?

The phrase den der literally means 'that there' and is very common in spoken Danish for pointing something out. A special rule applies here: when you use den der (or den her for 'this here'), the noun that follows must be in its basic, indefinite form without the -n or -t tacked onto the end.

What is the purpose of the 's' in the middle of 'afgangstavle'?

It is a connecting 's' used to glue two words together into a single compound noun. It links afgang (departure) and tavle (board or screen). You will encounter this extra 's' very often when learning Danish compound words.

Is the word 'tog' singular or plural in this sentence?

It could be either! The word tog is a neuter noun (et tog) and its plural form is exactly the same (flere tog). Furthermore, the possessive word vores (our) never changes its spelling regardless of the noun's gender or number. Therefore, we must rely entirely on context to know if they are looking for one train or multiple trains.
