Abstract: A trolley for track systems with essentially right-angled intersections is equipped with raisable and lowerable rollers which can be lowered to engage with, and raised to disengage with, one of the pairs of tracks. A common actuator (76,78) simultaneously lowers, in relation to the trolley, the rollers associated with one pair of tracks and raises the rollers associated with the intersecting pair of tracks.
