Abstract
The invention relates to a method to form a rail joint, in which staggerings () corresponding to each other are made in joinable solid-profile rail ends () of parts () of a rail () so that when a completed rail joint is viewed from above the rail heads bond; both rail ends are secured to a corresponding mounting; the rail ends secured to the mountings are brought against each other whereby said bonding is established; and the mountings that are against each other are secured to one another. The staggerings () are made in such a manner that the lower edges () of the rail ends () are left substantially unstaggered whereby the staggerings extend from these lower edges towards the top surfaces or the rail ends; and the rail ends () are welded by their lower edges () at their entire width to their mountings (). The invention also relates to a rail joint made by this method.
