In combination, a self guarded railway frog and a self guarded railway frog weld fixture,
- said self guarded railway frog comprising
- first and second raised flanges spaced apart from each other,
- said self guarded railway frog weld fixture comprising:
- a longitudinally extensive rail form having
- a longitudinal axis, and
- a first longitudinally extensive and generally vertical side edge configured to abut with said self guarded railway frog first raised flange and define a proper repaired geometry for a first portion of said self guarded railway frog first raised flange, and further configured to separate from material additively welded to said first portion of said self guarded railway frog first raised flange when said rail form is abutted thereto;
- a first transverse locator arm having a rail form coupling pintle about which said first transverse locator arm pivots relative to said rail form between a deployed position extending transversely from said rail form and a storage position extending longitudinally generally parallel to said rail form longitudinal axis;
- said first transverse locator arm configured in said deployed position to engage with and apply a first force in a first direction to said railway frog second raised flange while simultaneously applying a second force to said rail form in a second direction opposed to said first direction;
- a first lock configured to selectively lock said first transverse locator arm in at least said deployed position;
- a second transverse locator arm having a rail form coupling pintle about which said second transverse locator arm pivots relative to said rail form between a deployed position extending transversely from said rail form and a storage position extending longitudinally generally parallel to said rail form longitudinal axis, said second transverse locator arm rail form coupling pintle spaced apart from said first transverse locator arm rail form coupling pintle;
- said second transverse locator arm configured in said deployed position to engage with and apply a third force in a third direction to said railway frog second raised flange while simultaneously applying a fourth force to said rail form in a fourth direction opposed to said third direction;
- and
- a second lock configured to selectively lock said second transverse locator arm in at least said deployed position;
- said first and second transverse locator arms each configured in said deployed position to independently span across and contact a top of said railway frog second raised flange and distal thereto a top of said railway frog first raised flange, to thereby vertically locate said longitudinally extensive rail form relative to said railway frog first raised flange;
- whereby when said first and second transverse locator arms are in said deployed position, said rail form longitudinally extensive and generally vertical side edge abuts with and is in contact with a proper repaired geometry of said first portion of said self guarded railway frog first raised flange, and wear in said first portion of said self guarded railway frog first raised flange that deviates from said proper repaired geometry is defined by a repair weld gap between said rail form longitudinally extensive and generally vertical side edge and said self guarded railway frog first raised flange.
