The present invention relates to a train coupler adapted for energy absorption by the use of a deformation unit. According to the invention an axial expansion module is provided and mounted together with the deformation unit and an anchor in the housing of the train coupler. By expanding the axial expansion module after being mounted into the housing, the deformation unit and the anchor will be biased between the front and rear lugs of the housing and held in place by a predetermined force in the axial direction only. 112321. A train coupler () for coupling of a train car , comprising a bar () , which at a front end is adapted to engage with coupling means and at a rear end attached to an anchor () , the longitudinal extension of the bar () in a relaxed position defining an axial direction and a central axis of the train coupler () , wherein{'b': 3', '4', '4', '3', '3', '2', '3', '4', '5', '5', '5, 'i': a', 'b, 'the anchor () is arranged to interact with a deformation unit (), the deformation unit () positioned coaxially with the anchor () and after the anchor () in the axial direction from the bar (), the anchor () and the deformation unit () comprised in an housing () in-between a pair of front lugs () and a pair of rear lugs (),'}{'b': 7', '5', '3', '3', '4', '4', '5, 'i': a', 'b, 'at least one axial expansion module () is inserted in-between the front lugs () and the anchor () or in-between the anchor () and the deformation unit () or in-between the deformation unit () and the rear lugs (), and'}{'b': 7', '5', '7', '4', '3', '7', '4', '3', '5', '5, 'i': a', 'b, 'the axial expansion module () is arranged to be expandable in the axial direction and expanded after having been inserted into the housing (), the axial expansion module () exerting a predetermined force on the deformation unit () and the anchor () so that the axial expansion module (), the deformation unit () and the anchor () are held between the front lugs () and the rear lugs ().'}217.
