The basic design of the bogie came around after finding bogies with out compensating springing would not stay on our own garden railway. The springs are designed to push the wheel sets down to keep them in contact with the rail. This is especially important on tight curved track where the leading wheel is trying to ride up and over the rail. The positioning of the springs ensures loads are evenly distributed and down pressure isn't lost due to un even track.

The design even allows the wheel sets to drop when a train is unloaded.

If you are running on very level track with large sweeping curves then cheaper bogies are OK. In the real world tracks usually aren't level and these bogies will even cope with curves with superelevation.
