The correct spare wheelsets are a guarantee against pesky derailments
Only if suitable wheel geometry and wheel flange to run locomotives and cars smoothly

For all rail vehicles, the wheel flange on the inside of each tire shall ensure that the vehicle is run on the rails and can not slip off the rails. The flange is designed very differently and can be a bead or a right pane. As with the model train also plays at the model, the wheel geometry and the flange for a central role in the reliability and compatibility.
Since there are different wheel geometry and wheel flanges, even for the same model railroad tracks, are the use of incorrect wheel sets with false wheel flanges of one of the most common mistakes of novice model railroad. For example, have a scale railway models H0 gauge of 16.5 mm at different wheel profiles and wheel flanges, so that models run with isolated two-wire DC wheel sets in spite of them not reliable to gauge Marklin M-and K-rails. Particularly preferred model railroader wheelsystems with low wheel flanges ( "Fine Scale wheelsets). Here, the fault-free operation, however, depends very much on the used track system. For the model, the dimensions of the flanges in 310/311 MOROP-NEM are described.
