Why Railroad tracks do NOT prove a Flat Earth!

"Railroads PROVE a Flat Earth!", Learn why this isn't actually proof of a flat earth.

Eric Dubay and others commonly use railroad tracks to try to prove the earth is flat because railroad tracks are allegedly laid flat over hundreds of miles. Such an explanation fails to take into account one small detail: the way railroad tracks are actually laid out.

A simple google search on how railroads account for earth's curvature will bring you to scores of people who can testify to their job. One example of this is this Q and A page: https://answers.yahoo.com/question/index?qid=20090117165813AA0SxcY

"David K" who works at Norfolk Southern answers: "Rail is very flexible. A normal 39' piece will bend if picked up wrong. On the rail train 1400' pieces are loaded on 20 flat cars and the rail will bend a round the curves."
There you have it! Rail material is very flexible. But how flexible does it have to be for a long 1400 inch piece? With the earth's upward curvature being 8 inches per mile squared, we calculate:

1400 inches / 5280 inches = 0.2651515151515152 miles.
0.2651515151515152 miles * 0.2651515151515152 miles * 8 inches = 0.56244260789715355739210284664832 inches of curvature.

In other words, each long 1440 inch piece have to flex a grand total of half an inch. Taking into account the flexible nature of rail material and the great measures given to ensure it's conformance with earth's curvature, it is easy to see how railroad tracks fit inside the spherical curved earth. The flat earth explanation falls flat and treats railroad tracks as perfectly rigid. If they want rigid, they better consult the rectilineator experiment, and we all know where that led to... ;-)

Have you taken into account the distance between each sleeper that the tracks are laid on? The rail will be substantially shorter than 1400 inches. The nature of any solid object of any length's strongest points are also the shortest points within the length.

Bend a steel ruler at the furthest tip and then try to bend it at the shortest distance possible. Does it easily bend?

Calculate the distance between the sleepers, the bend needed for the curvature of the earth and calculate stress(breaking) points of the rail then apply the weight of a few hundred ton freighter, laws of motion, vibration, friction, heat, cold etc

Then do the same for a 1400 inch rail that has a sleeper only on the ends and tell me the predicted results

Not to mention that on order for the track to bend it has to have little or no resistance from opposing forces i.e. they're bolted to the sleepers. Each sleeper must have to move with the rail. The whole track would then increase and decrease in length under all variances named above and take into account the earths curvature!!

Is the earth round still?

I think not!
