انا في محطة القطر دلوقتي عشان عندي سفر.

Because Arabic usually leaves out the present-tense verb to be.

So انا في محطة القطر is literally I in the train station, but it means I am at the train station.

This is very normal in both Egyptian Arabic and Standard Arabic. You only use an actual verb for was / will be / has been, etc., not for simple present am/is/are in sentences like this.

في often means in, but in Arabic it can also cover English at depending on context.

So:

• أنا في البيت = I’m at home / in the house
• أنا في الشغل = I’m at work
• أنا في محطة القطر = I’m at the train station

English splits these ideas into in and at more often than Arabic does.

This is an idafa structure, often called a construct phrase.

محطة القطر literally means station of the train, which is how Arabic expresses the train station.

In an idafa:

• the first noun usually does not take ال
• the second noun can take ال
• the whole phrase becomes definite because the second noun is definite

So:

• محطة قطر = a train station
• محطة القطر = the train station

That is why محطة does not have ال here.

Yes. In Egyptian Arabic, القطر is a common word for the train.

A learner may also know the Standard Arabic word القطار. They are related, and القطر is the Egyptian colloquial form you will commonly hear in speech.

So:

• محطة القطر = the train station

If you already know قطار, just think of قطر here as the Egyptian everyday version.

دلوقتي means now, right now, or at the moment.

It is a very common Egyptian Arabic word and is definitely colloquial. In more formal Arabic, you would usually see الآن instead.

You may also hear slight spoken variations like دلوقت.

Examples:

• أنا مشغول دلوقتي = I’m busy right now
• تعالى دلوقتي = Come now

Here عشان means because or since.

So:

• أنا في محطة القطر دلوقتي عشان عندي سفر = I’m at the train station now because I have to travel / because I have a trip

In other contexts, عشان can also mean for or so that, so its exact meaning depends on the sentence.

Examples:

• جيت عشان أشوفك = I came to see you / so I could see you
• مقدرش أجي عشان تعبان = I can’t come because I’m tired

Literally, عندي سفر means something like I have travel or at me there is travel.

But idiomatically, it means:

• I have a trip
• I need to travel
• I’m traveling
• I have travel plans

Arabic often uses a noun where English would prefer a verb or a fuller expression.

So even though I have travel sounds odd in English, it is a natural Arabic way to express the idea.

عندي comes from عند plus the suffix -ي.

• عند = at
• -ي = my / me

So عندي literally means at me, but very often it functions like I have.

Examples:

• عندي عربية = I have a car
• عندي شغل = I have work
• عندي فكرة = I have an idea

So in عندي سفر, the structure is the same: I have travel / I have a trip.

Sometimes, yes.

You could hear:

• في محطة القطر دلوقتي عشان عندي سفر

if the context already makes it clear who is speaking about themselves.

But keeping انا is very natural and often clearer, especially because this sentence has no verb showing person. Since there is no equivalent of am, the pronoun helps anchor the sentence.

So:

• انا في محطة القطر دلوقتي... = clear and natural
• في محطة القطر دلوقتي... = possible, but more context-dependent

عندي سفر is natural and understandable. It means you have a trip or need to travel.

But another very common Egyptian phrasing would be:

• أنا في محطة القطر دلوقتي عشان مسافر

This is closer to I’m at the train station now because I’m traveling / because I’m about to travel.

So both work, but the nuance is slightly different:

• عندي سفر = I have travel plans / I have a trip
• مسافر = I’m traveling / I’m the one traveling

Both are good Egyptian Arabic.
