Learn Spanish (Spain): Mire, la estación está allí.

The word mire is the formal command form of mirar. You use it when talking to someone respectfully using usted (for example, a stranger you are asking for directions). If you were talking to a friend using tú, you would use mira.

Why does this sentence use está instead of es?

We use the verb estar (here as está) to talk about the physical location of people, places, or things. Even though a station's location is permanent, you always use estar for locations.

How do I know whether to use allí, ahí, or aquí?

These words show how far away something is. Use aquí for things close to you (here). Use ahí for things close to the person you are talking to (there). Use allí for things far away from both of you (over there).

Is the word estación always feminine?

Yes! A very helpful rule in Spanish is that almost every noun ending in -ción is feminine. That is why it is paired with the feminine article la.
