This is the Real SECRET Way You Were Supposed to get On a Rail Achievement in Minecraft Beta!
This way of getting On a Rail works until Java Edition Release 1.3 (?)
This is a combination of the Infinite Nether Portal Item duplication glitch + Minecart disappearing into NaN position glitch.
(Yes, please... don't try to say that the items are cheated in, they were not)

Random video showcasing the Infinite Item glitch: https://www.youtube.com/watch?v=rhGTgbL-EGg
It also works in Beta 1.5 and before, but you can't survive (not enough food/no way to get infinite food)
Using a better setup & everything done faster, you can do everything in less than 2 minutes.
(Fixed 65-67 seconds to get On a Rail after the setup)
