Yes. I'm way ahead of you. I wasn't going to post more nonsense but now I have to.

I was simply going to point out less than 50 lbs but we can use your 30 lbs. Not to get weird but given a college girlfriend could probably lay on top of her male counterpart we can assume an additional 100 lbs. This will be important in a minute. So 30 lbs of force times 2 means only 2 layers with people only 1 foot apart would be required to make the rail fail. 60 lbs. And we see there was much more than 2 layers of people.

Now why did I mention the weird girlfriend thing. It seems like it would take even less force applied to the poor individuals at the rail so they might not have even been in discomfort at the force required to make the rail fail.

Again, none of this matters and I'm not a structural engineer but just lowly electrical engineer. So we'll go with whatever your final word is on the matter.
