the structure: were a railroad strike to take place
I would like you to teach me the grammar about this sentence:
..., believing that the U.S. economic recovery would be threatened were a railroad strike to take place.
I couldn't find "subject" for "were," and then I guessed the meaning from the context.
I though it like this:
..., believing that the U.S. economic recovery would be threatened if a railroad strike were to take place.
Is this used the subjunctive mood and inversion?
Thank you.
