Abstract: This invention relates to a tipping rail vehicle including a wheeled frame and an open topped container body. It includes a connector pivotally connecting the body to the frame for rotation of the body at least partially about the pivot axis of the connector, with the pivot axis being normal to the intended direction of travel of the vehicle, and at least one formation on the container body for rotating the container body about the pivot axis to discharge material in the body from its open top. Preferably the container body is in the form of a substantially cylindrical drum with the pivot axis of the connector passing through parallel side walls of the body on or adjacent the axis of the cylinder with the body opening extending over the length of the cylindrical portion of the body between its side walls above the pivot axis of the connector. The invention additionally relates to a tipping arrangement for engagign and rotating the container body of the vehicle of the invention.
