Advantageously only one and preferably, the outer of the driving wheels acts to produce the pivotal movement of its corresponding driven wheel during cornering of the trolley. An override mechanism for user engagement or disengagement when the trolley is stacked is also provided. An arcuate handle bar and side bars may also be provided. Ease of maneuverability is assisted by differential offsets in the drive and driven wheels.
