Der Zielbahnhof fehlt im Fahrgastrechte-Formular.

Zielbahnhof means destination station.

It is a compound noun:

• Ziel = destination, goal
• Bahnhof = train station

So der Zielbahnhof is the station you are traveling to, not the one you started from.

Because the gender of a German compound noun usually comes from its last element.

Here, the last element is Bahnhof, and Bahnhof is masculine:

• der Bahnhof

So the full compound is also masculine:

• der Zielbahnhof

This is a very useful rule:

• das Haus → das Wohnhaus
• die Karte → die Fahrkarte
• der Bahnhof → der Zielbahnhof

No. In Zielbahnhof, Ziel is not acting like an adjective. It is the first part of a compound noun.

So:

• der Zielbahnhof = one noun made from two noun elements

That is why Ziel does not get any adjective ending.

Compare:

• der große Bahnhof = the big station
  
  • here große is an adjective
• der Zielbahnhof = the destination station
  
  • here Ziel- is part of the noun itself

Here fehlt means is missing or is absent.

The verb is fehlen.

So:

• Der Zielbahnhof fehlt. = The destination station is missing.

This is important because fehlen does not work like English to miss in I miss you.

Compare:

• Der Zielbahnhof fehlt. = The destination station is missing.
• Ich vermisse dich. = I miss you.

So in this sentence, fehlen means that some required information is not there.

Because with fehlen, the thing that is absent is usually the subject.

So:

• Der Zielbahnhof fehlt im Fahrgastrechte-Formular.

Literally, the structure is closer to:

• The destination station is missing in the passenger-rights form.

That is why the verb agrees with der Zielbahnhof:

• singular subject → fehlt

If it were plural:

• Die Zielbahnhöfe fehlen. = The destination stations are missing.

So der Zielbahnhof is in the nominative case.

im is a contraction of:

• in dem

So:

• im Fahrgastrechte-Formular = in dem Fahrgastrechte-Formular

This is very common in German:

• im = in dem
• am = an dem
• zum = zu dem
• vom = von dem

In this sentence, im means in the.

It is dative case.

The preposition in can take either:

• accusative for direction/movement into something
• dative for location

Here it describes a location, not movement:

• the information is missing in the form

So German uses dative:

• in dem Formular
• contracted: im Formular

That is why the phrase is:

• im Fahrgastrechte-Formular

That is just a normal German way to express where information appears in a document or where it is missing.

German often uses:

• im Formular
• im Antrag
• im Vertrag
• im Dokument

Even when English might prefer:

• on the form
• from the form
• in the document

So this is a good example of a place where you should not translate word-for-word too mechanically. In German, in is very natural here.

Fahrgastrechte-Formular is a compound noun meaning something like passenger rights form.

It is built from:

• Fahrgast = passenger
• Rechte = rights
• Formular = form

So this is a form related to passengers' rights, for example compensation or complaint rights in rail travel.

A natural English translation depends on context, but it is basically:

• passenger rights form
• passenger compensation form
• form for passenger rights claims

German often writes long compound nouns as one word, but a hyphen is also common and correct in many cases, especially for:

• readability
• official or administrative terms
• very long compounds

So the hyphen helps make the structure clearer:

• Fahrgastrechte
  • Formular

Without a hyphen, it can be harder to read quickly.

In many official contexts, the spelling with the hyphen is simply the preferred form of that term.

Because the compound is based on passenger rights in the plural, not just one single right.

• das Fahrgastrecht = passenger right
• die Fahrgastrechte = passenger rights

So Fahrgastrechte-Formular means a form connected with passenger rights as a whole.

This is common in German compounds: the first part can be singular or plural, depending on the meaning the word is built from.

Yes. German word order is flexible as long as the finite verb stays in the second position in a main clause.

So these are both possible:

• Der Zielbahnhof fehlt im Fahrgastrechte-Formular.
• Im Fahrgastrechte-Formular fehlt der Zielbahnhof.

The second version puts more focus on where the problem is.

That is a very common German pattern:

• place/time element first
• verb second
• subject after the verb

German often uses the definite article when talking about a specific item that is expected in a known context.

Here, the sentence is about a particular field or piece of information in a specific form:

• the destination station

So der Zielbahnhof sounds natural.

Without the article, Zielbahnhof fehlt, the sentence would sound more like a note, label, or very abbreviated checklist language. In full normal prose, der is the expected form.

A very literal breakdown is:

• Der Zielbahnhof = the destination station
• fehlt = is missing
• im Fahrgastrechte-Formular = in the passenger-rights form

So the structure is:

The destination station is missing in the passenger-rights form.

Even if the best English translation might be something like:

• The destination station is missing from the passenger rights form
• The destination station has not been entered in the passenger rights form

the German grammar is built around the destination station as the subject and is missing as the verb.
