Abstract (en)

[origin: CA3114829A1] In order to fix a rail (12) of a rail track using a rail machine (4), the rail machine (4) is moved in a working direction (100) so that at all times a rail portion (12) which is not attached to a cross-member (8, 10) of the rail track (2) passes through a thermal conditioning zone (30) of a thermal conditioning device (32) of the rail machine (4), a temperature of a surface region of the rail portion passing through the thermal conditioning zone (30) is modified using the thermal conditioning device (32) by generating a non-homogeneous temperature distribution in the rail portion, and the rail portion (12) is fixed to a cross-member (10) of the rail track, after modification of the temperature of the surface region of the rail portion, without waiting for the temperature distribution in the rail portion to be homogenised.
