Багажное отделение закрыто.

Literally, it means baggage/luggage section, department, or compartment.

• багажное = baggage-related, luggage-related
• отделение = section, department, compartment, branch, office

The exact English translation depends on context. In different situations, it could mean something like a baggage office, luggage compartment, or baggage department.

Because багажное has to agree with отделение.

The noun отделение is neuter singular, so the adjective must also be neuter singular:

• masculine: багажный
• feminine: багажная
• neuter: багажное
• plural: багажные

So багажное отделение is a normal adjective + noun combination with agreement.

A very common pattern in Russian is that nouns ending in -ие are neuter. Отделение follows that pattern.

Because it is neuter, other words connected to it also appear in neuter forms:

• багажное
• закрыто

So all the key words in the sentence match the gender and number of отделение.

It is in the nominative case.

In this sentence, багажное отделение is the subject, and закрыто tells you its state. So the structure is basically:

[багажное отделение] [закрыто]
= [the baggage department/compartment] [is closed]

In Russian, the verb to be is usually omitted in the present tense.

So where English says: The baggage department is closed

Russian simply says: Багажное отделение закрыто

But in the past or future, Russian does use forms of быть:

• Багажное отделение было закрыто = The baggage department was closed
• Багажное отделение будет закрыто = The baggage department will be closed

Because закрыто is the form Russian normally uses when saying that something is closed.

Compare:

• закрытое отделение = a closed department/compartment
  
  • this is the full form, used before a noun
• отделение закрыто = the department/compartment is closed
  
  • this is the short form, used as the predicate

This is very common in Russian:

• Дверь закрыта = The door is closed
• Окно открыто = The window is open

So in your sentence, закрыто is exactly the form you would expect.

For a learner, the most useful way to think of it is as a predicate adjective/short-form participle meaning closed.

It is connected historically to the verb закрыть / закрывать = to close, but in this sentence it functions like a description of the noun’s state.

You can see agreement forms:

• закрыт — masculine
• закрыта — feminine
• закрыто — neuter
• закрыты — plural

No. Russian has no articles like a/an or the.

So Багажное отделение закрыто could, in theory, mean either:

• The baggage department is closed
• A baggage department is closed

In real life, context usually makes it clear. On a sign or announcement, it will normally be understood as the baggage department/compartment.

Yes, Russian word order is flexible, but the neutral, most straightforward order here is:

Багажное отделение закрыто

You could also say: Закрыто багажное отделение

That version is more marked and may sound more like an announcement or give extra emphasis to closed. So for standard learning purposes, the original order is the best one to remember.

You would make both the adjective and закрыто plural:

Багажные отделения закрыты
= The baggage departments/compartments are closed

Notice the changes:

• багажное → багажные
• закрыто → закрыты

This shows the same agreement pattern as in the singular sentence.

Yes, sometimes, but it means something slightly different.

• закрыто = closed
• не работает = not working / not open for service

For example:

• Магазин закрыт = The store is closed
• Касса не работает = The ticket desk is not operating

So Багажное отделение закрыто specifically tells you that it is closed, not just unavailable or malfunctioning.
