Questions & Answers about Rano wsiadam do tramwaju, a moja siostra wysiada dwa przystanki później.

Why is it rano and not w rano?

Rano by itself is a very common adverb meaning in the morning or in the morning hours.

So:

• Rano wsiadam do tramwaju = In the morning, I get on the tram

You do not normally say w rano.

Compare:

• rano = in the morning
• wieczorem = in the evening
• nocą = at night

If you want a fuller phrase, you can also say:

• wczesnym rankiem = early in the morning
• o poranku = at dawn / in the morning

But in everyday Polish, rano is the natural choice here.

Why are wsiadam and wysiada in the present tense if the sentence describes a usual action?
