Questions & Answers about densha no jouhou o kakuninshimashita.

How do you read 電車の情報を確認しました?

It is read:

でんしゃのじょうほうをかくにんしました
densha no jouhou o kakunin shimashita

A natural English gloss is I checked the train information or I confirmed the train information.

What does の mean here?

の links two nouns together.

In this sentence:

電車 = train
情報 = information
電車の情報 = train information / information about the train(s)

So の is showing a relationship between the two nouns. In English, this is often translated as of, about, or sometimes just by putting one noun before the other.

Why is を used?

を marks the direct object of the verb — in other words, the thing that was checked.

So here:

電車の情報 = the train information
を確認しました = checked/confirmed it

Putting it together:

電車の情報を確認しました = checked the train information

確認しました is the polite past form of 確認する.

確認する = to confirm, to check, to make sure
確認しました = confirmed / checked

This verb often implies checking something carefully to make sure it is correct or to verify it.

So compared with some other verbs:

見ました = looked at / saw
調べました = investigated / looked up
確認しました = checked/confirmed

If you just glanced at train info, 見ました might work.
If you looked it up in detail, 調べました might work.
If you checked it to make sure of the details, 確認しました is very natural.

Why is the verb in the past tense, しました?

Because the sentence is describing an action that has already been completed.

確認します = will check / check
確認しました = checked / did check

Japanese often uses the past tense when reporting that something has been done.

So 電車の情報を確認しました means that the checking has already happened.

Why is there no subject, like I?

Japanese very often leaves out the subject when it is clear from context.

So even though the sentence does not say 私は, the meaning is often understood as:

I checked the train information
or sometimes We checked the train information

The exact subject depends on the situation. This is completely normal in Japanese.

Does 電車の情報 mean information about trains, or information from a train?

In this sentence, it normally means information about the train or train-related information.

For example, it could mean:

departure time
delay information
platform information
route information

The particle の can show different kinds of relationships, but here the most natural interpretation is information about trains.

Is this sentence polite?

Yes. It is in the polite form because of しました.

plain form: 電車の情報を確認した
polite form: 電車の情報を確認しました

The polite version is appropriate in many everyday situations, especially when speaking to someone you do not know well, to a teacher, a coworker, or in customer-service-style language.

Could I say this without spaces, as normal Japanese writing?

Yes. Normal Japanese writing would usually be:

電車の情報を確認しました。

The spaces are often added only for learners to make the sentence easier to read.

Can this sentence be translated as I checked the train schedule?

Sometimes, depending on context, but not literally.

情報 means information, which is broader than schedule. It could include:

timetable
delay notices
platform changes
service updates

If you specifically mean schedule or timetable, Japanese would more directly use words like:

時刻表 = timetable
スケジュール = schedule

So 電車の情報を確認しました is broader than just I checked the train schedule.

Why use 確認しました instead of a simpler verb like 見ました?

Because 確認しました sounds more purposeful.

Compare them:

見ました = I looked at it
確認しました = I checked it / verified it

If you want to say you looked at the train info to make sure of something, 確認しました is better.

For example:

電車の情報を見ました = I looked at the train information
電車の情報を確認しました = I checked the train information

The second one suggests more intention and certainty.
