Why is there no word for “in/at” before 早上? Can I say 在早上她常常…?

In Chinese, specific time words (like 早上, 晚上, 星期一, 三点) are usually used directly, without a preposition like in/at.

So:

are both natural and common.

You can say 在早上, but:

在早上她常常… sounds more formal or bookish.
In everyday speech, native speakers would almost always just say 早上她… or 她早上….

So the sentence is natural without 在.

Why is 常常 placed after 她 and before 从地铁站? Could it go in other positions?

常常 is a frequency adverb (often, frequently). The most typical place for frequency adverbs is:

Subject + 常常 + (place/time etc.) + verb…

In your sentence we have:

早上　她　常常　从地铁站　走到公交站…

Some common, natural variations:

早上她常常从地铁站走到公交站…
她早上常常从地铁站走到公交站…
她常常早上从地铁站走到公交站… (less common, but possible if you want to stress “in the morning” as the time when this often happens)

Positions that are awkward or wrong:

So the given position (after the subject, before the rest of the verb phrase) is the most neutral.

What exactly do and do here? Could I leave one of them out?
