When the HO scale ballast is distributed, Josh takes an angled painting brush to spread it out and brush the excess off of the track, focusing on one rail and then the other. An easy way to remove the excess on the ties is to simply use a finger. To glue it all down, Josh sprays the track with some wet water in a spray bottle that produces a finer mist. Starting in the middle of the track, he

The negative impact of the ballast on the service life of the track led to initial designs of ballastless track. The ballast is replaced by sub-layers of concrete or asphalt which, unlike ballast, have no or only slight plastic deformation. The lack of elasticity of these layers is compensated by the conscious use of elastic components. Only in this way can the necessary deflection of the
