Vi har en hurtig omstigning i Aarhus, så vi må skynde os til den anden perron.

Yes. Vi har literally means we have, and in this context Danish uses have much like English does in sentences such as We have a quick transfer in Aarhus.

It refers to a situation in the journey:

• Vi har en hurtig omstigning = We have a quick transfer

So har is not possession in the strict sense only; it can also describe what is happening in your travel plans, schedule, or situation.

Omstigning means a transfer, especially in travel: changing from one train, bus, etc. to another.

It comes from the verb at stige om, which means to change trains / change transport.

Examples:

• Vi har en omstigning i Odense. = We have a transfer in Odense.
• Der er kun fem minutters omstigningstid. = There are only five minutes for the transfer.

So in this sentence, en hurtig omstigning means a transfer that must happen quickly.

Because omstigning is a common-gender noun in Danish, so it takes en, not et.

That affects the adjective too:

• common gender singular indefinite: en hurtig omstigning
• neuter singular indefinite: et hurtigt ...

So the adjective hurtig stays in its basic form here because omstigning is an en-word.

A useful comparison:

• en hurtig togforbindelse
• et hurtigt skift

The -t on the adjective appears with et-words, not en-words.

I usually means in and is used for cities, countries, and many enclosed or defined places.

So:

• i Aarhus = in Aarhus
• i København = in Copenhagen
• i Danmark = in Denmark

Here it marks the place where the transfer happens.

Here så means so or therefore.

It connects the two ideas:

• Vi har en hurtig omstigning i Aarhus
• så vi må skynde os til den anden perron

In other words:
We have a quick transfer in Aarhus, so we need to hurry to the other platform.

This så is a conjunction linking cause/result.

Here må means must, have to, or need to.

So:

• vi må skynde os = we must hurry / we need to hurry

The verb is at måtte. In Danish, må can express:

1. necessity
   
   • Jeg må gå nu. = I have to go now.
2. permission
   
   • Må jeg komme ind? = May I come in?

In this sentence it clearly expresses necessity, not permission.

Because at skynde sig is a reflexive verb in Danish. It means to hurry.

That means it uses a reflexive pronoun:

• jeg skynder mig = I hurry
• du skynder dig = you hurry
• vi skynder os = we hurry
• de skynder sig = they hurry

So vi må skynde os literally means we must hurry ourselves, but in natural English just we must hurry.

This is very common in Danish, and English learners often need to remember that some verbs require a reflexive pronoun even when English does not.

Because til shows movement toward a destination.

• til den anden perron = to the other platform

If you were already there, you would more likely use på:

• Vi står på den anden perron. = We are standing on the other platform.

So the contrast is:

• til = movement to
• på = location on / at

In this sentence, they need to move from one platform to another, so til is the natural choice.

Anden means other or second, depending on context.

Here den anden perron means the other platform.

A few useful points:

1. anden often means the other one when there are two relevant options.
2. It can also mean second in some contexts:
   • første, anden, tredje = first, second, third

In a station context, den anden perron is usually understood as the other platform rather than simply platform number two.

If you wanted to say platform 2, you would normally say something like:

• perron 2

Because Danish usually uses double definiteness when a noun has an adjective.

With an adjective, Danish often needs:

1. a definite article before the adjective
2. the adjective in definite form

So:

• perron = platform
• den anden perron = the other platform

You do not say anden perronen here.

Compare:

• perronen = the platform
• den store perron = the big platform
• den anden perron = the other platform

This pattern is very important in Danish.

Yes, it is normal.

Så here is a conjunction linking two main clauses:

• Vi har en hurtig omstigning i Aarhus
• så vi må skynde os til den anden perron

After this kind of så, Danish uses normal main-clause word order:

• subject + finite verb
• vi må

So:

• så vi må skynde os = so we must hurry

This is different from subordinate-clause word order, where adverbs often come before the finite verb. But in this sentence, the structure is straightforward main-clause order.

Sometimes yes, but the nuance is a little different.

• må often suggests necessity because of the situation
• skal often suggests requirement, plan, or something that is supposed to happen

In this sentence, må sounds natural because the quick transfer creates a practical necessity:

• We have a quick transfer, so we need to hurry.

If you said så vi skal skynde os, it could also work, but må fits the idea of we really have to, given the circumstances especially well.

Yes. Perron is the standard word for a railway platform.

Examples:

• Hvilken perron går toget fra? = Which platform does the train leave from?
• Vi skal over på en anden perron. = We need to go over to another platform.

So in this sentence, den anden perron is exactly the expression you would expect at a train station.
