FIELD: construction, road engineering.
SUBSTANCE: invention refers to the field of railway transport, namely to structures of track crossing. Crosspiece for rails crossing comprises core (1) with working edges (2), (3), crossing in its mathematical centre (4), and two wing rails (5), (6). Crosspiece is arranged with rise of longitudinal profile in zone of wheels rolling from core (1) to wing rails (5), (6) and back. Maximum ordinate of its longitudinal profile is arranged in cross section (19), passing through mathematical centre (4) of crosspiece.
EFFECT: improved conditions for rolling stock passage through crosspiece and increased service life of crosspiece for rail crossing by improvement of its longitudinal profile shape.
