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... ;-)
