A plastic drum is formed with a generally circular sidewall and a bottom. The sidewall includes two sets of handles, one set being disposed near a top rim, and a second set being disposed at an intermediate position below the first set. A third set of handles is disposed at the bottom of the drum. The bottom of the drum is profiled to form a channel that accepts a rail having predetermined at least a predetermined width. Several drums can be turned upside to support rails in their channels and form barriers or traffic lanes.
