An apparatus for transporting goods to and from shelves has a carriage supported frame travelling on inverted T-rails secured to the floor. A vertically extending guide member rides in an overhead U-rail, vertically aligned with the T-rails. The carriage has at least one swivelling axle with wheels travelling on the rails and at least one carriage guiding device with guide rollers guided by an upwardly extending central web of the inverted T-rails except in rail junctions where the central web is omitted. In the rail junctions, guide rails with a U-cross-section take over the guiding of at least one of the guide rollers of each carriage until the central web of the inverted T-rail in the branching rail section takes over the guiding again. Thus, the carriage may be guided selectively into any branching rail section without using railroad type switches nor transfer bridges in the rail system. This construction also avoids the need for separately controllable guiding devices since the guiding of the guide rollers or at least one guide roller is continuous and automatic.
