My face must be conveying

[JACEK1]

Hello everybody!

I have always enjoyed travelling by train or streetcar, anything that rolls on rails. Unfortunately, in our little town there are only water trams also known as ferries.

A few days ago, while searching for an article about a handcar (a kind of a trolley that glides over a rail-track thanks to using the power of human muscles) on the Internet, I came across the article "This Man Bikes the Railroad Tracks. Can he do that?"

It is from this article that I chose one sentence. It can be found below and reads as follows:

My face must be conveying an air of trepidation as I gawk at the strange contraption he suggests that I ride.

I understand the above sentence as follows:

When I look stupidly at the strange piece of equipment which/that he suggests that I ride, there must be a trace of anxiety written all over my face.

What do you think?

The reason I used "my" own words as substitutes for the original ones in the sentence was to make sure that I got it right.

"When" suggests that you repeatedly gawk at the contraption. You'd need "while" or "as" there. Either word will tell the reader that the gawking and the visible anxiety are happening at the same time.
