Почасовой тариф включает док-станцию.

Почасовой means hourly or charged by the hour.

It is built from:

• по- = a pattern often used for rates or distribution
• час = hour
• -овой = an adjective ending

So почасовой тариф literally means something like an hourly rate/tariff.

Because тариф is a masculine singular noun.

Russian adjectives must agree with the noun they describe in:

• gender
• number
• case

So in the nominative singular:

• masculine: почасовой
• feminine: почасовая
• neuter: почасовое

Since тариф is masculine, почасовой is the correct form.

Тариф means rate, fee, or pricing plan.

In this sentence, почасовой тариф is most naturally:

• the hourly rate
• the hourly plan
• the hourly pricing

It is a common word in contexts like transport, rentals, mobile plans, parking, and subscriptions.

Yes, включать / включить can mean different things depending on context.

Common meanings include:

• to switch on
• to include

In this sentence, Почасовой тариф включает док-станцию, the subject is the hourly rate, so includes is the natural meaning:

• The hourly rate includes the docking station.

If the subject were a person, then switches on might make sense:

• Он включает свет. = He switches on the light.

Включает is a conjugated verb: he/she/it includes or includes.

The dictionary form is включать (imperfective) or включить (perfective).
Here we need a finite verb for the sentence, so Russian uses:

• включает = includes

This is 3rd person singular present tense of включать.

Because it is the direct object of включает.

The verb включает takes an object in the accusative case.
The noun is док-станция in the dictionary form (nominative singular), but in the accusative singular it becomes:

• док-станция → док-станцию

This happens because it is a feminine noun ending in -я.

The dictionary form is док-станция.

Case forms:

• nominative: док-станция
• accusative: док-станцию

So if you look it up in a dictionary, search for док-станция, not док-станцию.

Because it is a compound borrowed term, based on English dock station / docking station.

In Russian, some borrowed compound words are written with a hyphen, especially newer technical terms.
So док-станция is the standard written form.

It is a borrowing, but it is used as a normal Russian noun.

Russian often adapts technical English words and gives them:

• Russian spelling
• Russian pronunciation
• Russian grammar

So док-станция behaves like a regular feminine noun and declines by case:

• док-станция
• док-станции
• док-станцию, etc.

Russian has no articles like a/an/the.

So:

• Почасовой тариф can mean an hourly rate or the hourly rate
• док-станцию can mean a docking station or the docking station

The exact meaning depends on context.

Yes. Russian word order is more flexible than English because case endings show the grammatical roles.

The neutral order here is:

• Почасовой тариф включает док-станцию.

But you could also say:

• Док-станцию включает почасовой тариф.

That version is more marked and may emphasize док-станцию.
In ordinary usage, the original order sounds more natural.

The stress is:

• почасово́й
• тари́ф
• включа́ет
• до́к-ста́нцию

Stress is important in Russian, because it is not always predictable from spelling.
