A natural breakdown is:

• この電車なら = if it’s this train / as for this train
• 乗り換えなしで = without changing trains / with no transfer
• 空港まで = to the airport / as far as the airport
• 行けます = can go

So the structure is roughly:

[condition/topic] + [manner/condition] + [destination] + [can go]

なら is often used to present something as a condition or topic, like:

• if it’s ...
• when it comes to ...
• as for ...

So この電車なら means something like:

• If it’s this train, ...
• With this train, ...
• As for this train, ...

In this sentence, it implies that this particular train is suitable for getting to the airport without a transfer.

Using は would simply make this train the topic:

• この電車は、乗り換えなしで空港まで行けます。

That sounds like a plain statement about the train.

Using なら adds a nuance of selection, contrast, or condition:

• If you take this train, you can get to the airport without changing trains.

This is very common when giving advice or answering a question like Which train should I take?

乗り換え means transferring or changing from one train, bus, etc. to another.

It comes from the verb 乗り換える, which means:

• to change trains
• to transfer

So:

• 乗り換えなし = no transfer
• 乗り換えあり = there is a transfer / transfer required

Here, で shows the condition/state/manner in which the action happens.

So 乗り換えなしで行けます means:

• can go without transferring
• can get there with no transfer

You can think of なしで as a set expression meaning without in many cases.

Examples:

• 予約なしで入れます = You can enter without a reservation.
• お金なしで生活できない = I can’t live without money.

Both are possible, but they feel a little different.

• 乗り換えないで = without changing trains
  This directly uses the verb 乗り換える.

• 乗り換えなしで = with no transfer / without a transfer
  This uses the noun 乗り換え plus なし.

In train and travel situations, 乗り換えなし is especially common because it sounds like a practical travel description, similar to nonstop or no transfer.

まで means up to, until, or as far as.

In this sentence, 空港まで means:

• to the airport
• as far as the airport

It marks the endpoint or destination.

Compare:

• 駅まで歩きます = I walk to the station.
• 3時まで待ちます = I’ll wait until 3.

So まで can be used for both place and time.

行けます is the potential form of 行く, meaning:

• can go
• am able to go

So the sentence is not just saying that the train goes there. It is saying that it is possible to get there on this train.

That is important because the point is about convenience or accessibility:

• この電車なら、乗り換えなしで空港まで行けます。
  With this train, you can get to the airport without transferring.

If you said 行きます, it would sound more like:

• This train goes to the airport without transfers.

That is sometimes possible in context, but 行けます is very natural when talking to a person about what they are able to do.

In English we usually translate it as you can go, even though Japanese often leaves the subject unstated.

So the understood meaning is something like:

• If you take this train, you can get to the airport without changing trains.

Japanese does not need to explicitly say you here. The subject is understood from context.

Yes. この電車 means this train, referring to a train near the speaker or one currently being discussed.

• この must be followed by a noun.
• So この電車 = this train

Compare:

• この電車 = this train
• その電車 = that train near the listener or previously mentioned
• あの電車 = that train over there

The comma is not required in every case, but it is very natural here.

It helps separate:

• この電車なら = the condition/topic
• the rest of the statement

So it reflects a pause, like:

• As for this train, you can go to the airport without changing.

Japanese commas often show rhythm or clarity more than strict grammar rules.

Yes. Japanese word order is flexible as long as the particles make the relationships clear.

For example, these are all possible:

• この電車なら、乗り換えなしで空港まで行けます。
• この電車なら、空港まで乗り換えなしで行けます。

Both are natural. The original version puts 乗り換えなしで before 空港まで, which emphasizes the no-transfer point early.

In expressions like this, なし behaves like a noun-like element meaning without or none.

So:

• 乗り換えなし = no transfer
• 予約なし = no reservation
• 問題なし = no problem

Then adding で lets it connect to the verb:

• 乗り換えなしで行けます = can go with no transfer

This pattern is very common in everyday Japanese.

No. Standard Japanese is normally written without spaces:

この電車なら、乗り換えなしで空港まで行けます。

Spaces are often added in beginner materials to make the sentence easier to read, but they are not used in normal writing.

It sounds like practical guidance, such as at a station, ticket counter, or in conversation when helping someone choose a route.

The nuance is:

• This is the convenient train to take
• You won’t need to transfer
• You’ll be able to get to the airport directly

So it is not just a dry fact about the train; it often feels like helpful advice or a recommendation.
