Abstract (en)
[origin: EP1842962A1] The method involves detecting both ends (24) of a rail using a rail traction device in a separating section. A traction force necessary for contracting the rail ends and an actual rail temperature are recorded by force and temperature measuring devices for evaluating the length of a replacement rail to produce a target-rail tension. Another separating section is arranged at a distance to the former separating section by path measurement, where the distance is estimated based on the selected length of the replacement rail. Independent claims are also included for the following: (1) a machine with a frame movable on a rail carriage (2) a machine arrangement for making a rail weld.
