हम शाम की ट्रेन से जाएँगे।

A useful breakdown is:

• हम = we
• शाम = evening
• की = a linking form of का/की/के, used here to connect evening and train
• ट्रेन = train
• से = by / via / using
• जाएँगे = will go

So the structure is roughly:

we + evening-associated train + by + will go

Very literally, it is close to We will go by the train of the evening, which natural English expresses as We will go by the evening train.

Hindi often uses noun + का/की/के + noun where English uses a noun as an adjective.

So:

• शाम की ट्रेन = evening train
• सुबह की फ्लाइट = morning flight
• रात का खाना = night meal / dinner

The idea is not really possession in the English sense. It is more like the train associated with the evening.

Because का/की/के agrees with the noun that comes after it, not with शाम.

Here the noun after it is ट्रेन, and ट्रेन is treated as feminine singular in Hindi. So the correct form is:

• शाम की ट्रेन

Compare:

• शाम का खाना = dinner because खाना is masculine singular
• शाम के कार्यक्रम = evening programs because कार्यक्रम is masculine plural
• शाम की बस = evening bus because बस is feminine

Here से means by, via, or using. It marks the means of travel.

So:

• ट्रेन से जाना = to go by train
• बस से जाना = to go by bus
• कार से जाना = to go by car

In this sentence, ट्रेन से tells you how the speaker will go.

Yes, but the nuance changes.

• ट्रेन से जाएँगे = we will go by train
  Focus: the means of transport

• ट्रेन में जाएँगे = we will go in/on the train
  Focus: being inside/on the train

When talking about travel generally, से is very common and natural. में is also possible, but it highlights the physical location more.

This is an important difference.

• शाम की ट्रेन = the evening train
  The train itself is the one associated with evening.

• शाम को ट्रेन से = by train in the evening
  Here शाम को tells you when the action happens.

So:

• हम शाम की ट्रेन से जाएँगे। = We will go by the evening train.
• हम शाम को ट्रेन से जाएँगे। = We will go by train in the evening.

These are related, but not exactly the same.

जाएँगे is a future form of जाना (to go).

It tells you:

• the action is in the future
• the subject is plural or honorific
• the ending -गे is typically used for masculine or mixed-gender plural groups

So with हम, जाएँगे means we will go.

If the speakers were an all-female group, you might hear:

• हम शाम की ट्रेन से जाएँगी।

So the ending can reflect gender as well.

Yes, but Hindi word order is somewhat flexible compared with English.

The neutral order here is:

• हम (subject)
• शाम की ट्रेन से (by the evening train)
• जाएँगे (will go)

Hindi very often puts the main verb at the end, so जाएँगे naturally comes last.

You can move some parts for emphasis in conversation, but this sentence is the normal, straightforward order.

Hindi does not have articles like a, an, and the.

So Hindi often leaves that idea to context.

That means शाम की ट्रेन could, depending on context, be understood as:

• the evening train
• an evening train

In many real situations, context makes it clear which one is meant.

ट्रेन is completely normal and very common in everyday Hindi. It is a widely used loanword.

You can also say:

• रेलगाड़ी

But in ordinary speech, ट्रेन is often the more natural choice.

So:

• हम शाम की ट्रेन से जाएँगे। = perfectly natural
• हम शाम की रेलगाड़ी से जाएँगे। = understandable, but less common in casual speech

जाएँगे is pronounced roughly like jaa-EN-gay, with a slight nasal quality on the middle vowel.

The mark ँ shows nasalization. You do not pronounce it as a full extra consonant; instead, it nasalizes the vowel.

So जाएँगे is not pronounced like three completely separate English-style syllables. It flows together smoothly.

If you are just starting out, a reasonable approximation is:

• hum shaam kee train say jaa-engay

That is not perfect, but it will help you get close.
