Questions & Answers about asa no densha wa joukyaku ga ookute, eki no hoomu mo kanari komimasu.

Why is it 朝の電車 and not something like 朝に電車?

朝の電車 means morning train or trains in the morning. Here, 朝 is being used like a noun that modifies another noun, and の connects them.

So:

• 朝 = morning
• 電車 = train
• 朝の電車 = morning train(s)

If you said 朝に電車, that would sound incomplete, because に marks a time for an action, but here there is no verb directly after it. の is the natural choice when one noun describes another noun.

Why is there both は and が in the same sentence: 電車は乗客が多くて?

This is a very common Japanese pattern.

• 電車は sets the topic: as for the morning trains...
• 乗客が多い gives the specific statement: the passengers are many

So the structure is roughly:

• As for morning trains, passengers are many...

In more natural English, that becomes something like:

• Morning trains have a lot of passengers...

Japanese often uses は for the bigger topic and が for what is being described inside that topic.
