16. F5? That probably could topple a locomotive.

This one was only an F1 or F2.

There's more involved than only weight. How many square feet of surface area of the building were facing the winds?

I can't guess how much a brick church weighs, but it's still going to contain a lot of empty space. With its broad outer walls, it acts like an airfoil.

Locomotives are dense, low to the ground, and don't present as much surface area as either a one- or two-story building. The cars in the train are more easily blown over, as they are lighter. Box cars and covered hoppers especially present a big flat area to oncoming winds. F2 tornado winds are something like 100 to 150 mph; I'm not sure.

A double-stack container train, with its big broad area, sticking way up higher than locomotives, would go over in a stiff breeze.

I'm not saying that a locomotive can't be blown over, but it's going to take some effort.

Here are drone pictures of the scene. The cars were easily derailed. I believe 31 of them went over.

BNSF locomotives show the effects of a storm that saw some of the train’s freight cars derailed by a tornado. Sam Brodersen

WAVERLY, Neb. — A BNSF train was derailed this afternoon when it was struck by a tornado between Waverly and Lincoln, Neb.. The tornado was one of a series in an outbreak across the Midwest today (Friday, April 26).

KSBN-TV reports the incident occurred about 3:25 p.m., according to a BNSF representative. There were no injuries to the crew and no hazardous materials were released.

It's like this: if there were a tornado headed right at me, and a building and a locomotive were at an equal distance from me, I'd head for the locomotive.

And good afternoon to you too.
