Because we need so many pieces of rails for our sheet metal work.
Because how much easier do you want it to be ?: Score a rail anvil. Such a piece of rails (approximately 25 cm / 15 kg) can be used in various ways. You can use the top (tread) to form repair parts. By tilting the rails, you can use the side for tapping an edge to create a seam. Rail tracks are made of the hardest steel.
Due to its dimensions and weight, such a tool is also very useful as a door opener.
Consult your local station manager or a company such as Rustbuster!
Note: The removal of rails for hobby purposes includes heavy penalties. Even if it concerns hardly used routes such as the Betuwe line
