This invention relates to a tipping rail vehicle including a wheeled frame and an open topped container body characterised in that it includes means (38) pivotally connecting the body (12) to the frame (14, 16, 18 and 20) for rotation of the body (12) at least partially about the pivot axis (26) of the connecting means (38) with the pivot axis (26) being normal to the intended direction of travel of the vehicle (10) and at least one formation (36) on the container body (12) for rotating the container body (12) about the pivot axis (26) to discharge material in the body (12) from its open top (30). Preferably the container body (12 is in the form of a substantially cylindrical drum with the pivot axis (26) of the connecting means (38) passing through parallel side walls (22, 24) of the body (18) on or adjacent the axis (26) of the cylinder with the body opening (30) extending over the length of the cylindrical portion of the body (12) between its side walls (22, 24) above the pivot axis (26) of the connecting means (38). The invention additionally relates to a tipping arrangement (80) for engaging and rotating the container body (12) of the vehicle of the invention.
