Would VS Would have

Hi!

*****

The noise of the train filled the air now. The bridge began to shake as the train charged across it. I was on the narrow walkway on one side of the tracks. It was so narrow that the wind of a passing train would blow me off the bridge. My legs felt like water. My mouth opened by itself. I couldn’t move. Far in front I could see my friends screaming, “Run!” I thought that I would be soon joining them. That thought unlocked my body. I jumped to my feet. My left foot almost slipped, but I recovered and ran on. When I was almost across, finally I jumped and landed onto the solid ground. And when the train passed completely, I felt a warm hand on my neck. It was Chris’s.

The underlined part, the context considered, definitely means, "It was so narrow, so if there had been the wind of a passing train, I would have been blown off the bridge by the wind", referring to the past situation.

Then, the sentence above is correct one, or simply wrong?

colorady says that it should be "It was so narrow that the wind of a passing train would have blown me off the bridge", and I think I should agree with the opinion.

PS: The name of member coloraday starts not with a capital "C", then "coloraday says that" is allowed?
