Rails can be duplicated when they are pushed downwards (or sideways) by a piston.
In the setup pictured, when the rail on a block is pushed downwards by the top piston and block, the rail is remains placed on the lower block, but also drops an extra rail, allowing it to be infinitely duplicated.
[media]Also affects other types of rail also, though these break when pushed back up.
This issue was brought to my attention by means of this video: https://youtu.be/J0OeQ--oSxU

After an hour of testing this i have concluded it dose happen but its extremely rare for it to work and currently i have found no possible way to automate it reliably like the video cliams. So my cunclusion is its not a real dupe bug because it works once every ~30 tries for me and its impossible to automate. I will continue testing later and see if it can be made 100% reliable or automatable making it a real dupe glitch and then actually making it a problem.
After half an hour of experimenting i have created a fully automatic rail farm, but like i said before its extremely rare for the dupe to occour but it is AFK friendly making it still be classed as a dupe farm. now this has become a problem. Unless you need rails...

As seen in the setup pictured here, the duplication of the rail can be reliably reproduced in great quantities.
