Learn English – What does “ducked into an arched doorway heading for the subway – and got lost…” mean in this passage

phrase-meaningsentence-meaning

I turned into Grand Central from Vanderbilt Avenue, and went down the steps to the first level, where you take trains like the Twentieth Century. Then I walked down another flight to the second level, where the suburban trains leave from, ducked into an arched doorway heading for the subway — and got lost. That's easy to do. I've been in and out of Grand Central hundreds of times but I'm always bumping into new doorways and stairs and corridors.

This sentence referred to the man or trains?! I don't get the meaning clearly. If it referred to the man why he got lost if that is easy to do?! as mentioned in the bold sentence.

The context is from the short story named "The Third Level" by Jack Finny.

As @EllieK said, the sentence means that

  1. I turned into Grand Central from Vanderbilt Avenue,
  2. I went down the steps to the first level,
  3. I walked down another flight to the second level,
  4. I ducked into an arched doorway, and
  5. I got lost.

(Of course the first item on the list means that he entered the station, not that he became the station.)

The speaker does not mean that finding his way is easy to do. On the contrary, he means that getting lost is easy, because there are lots of doorways and stairs and corridors.
