HELP ME WITH THIS SENTENCE PLEASE!

[roseriver1012]

Subway Line4, _________ into use in September 2009, has made traveling in Beijing easier.
A. having been put B. put
Which one do you think is proper for the sentence? or both? And please, tell me your reason. Thanks a lot!

p.s. What do you think is the grammatical function of "_________ into use in September 2009" in this sentence? What if I change the sentence into this: _________into use, Subway Line4 has made traveling in Beijing easier.?

I am not a teacher.

I would use the simple "put into use."

There is nothing wrong with "having been put" but it is needlessly wordy and potentially confusing for non-native speakers.

anyone can explain it in terms of grammar?

You need to consider the unwritten/unspoken words here. As a full sentence, it would say:

Line 4, which was put into use in September 2009......

However, we simply remove the "which was" and you are left with "Line 4, put into use......." which makes just as much sense. We are given a date, which is clearly in the past, so we don't really need to add extra information to show that we are referring to the past.

It works when you are talking about when people were born. For instance:

Beethoven, born in December 1770, was one of the greatest composers of his time.

What you are actually saying is:

Beethoven, who was born in December 1770......

but "who was" is redundant though grammatically perfectly correct.
