HO Ballast Size - Model Railroader Magazine - Model ...

Also it needs to be noted that when comparing types of HO scale track, different ballast sizes need to be considered. Atlas HO code 100 ties are 13" scale inches wide. Code 83 8". The spacing is about the same. Using a smaller ballast distracts seems to cause the eye to not see the extra wide code 100 tie.

The complete guide to ballasts for fluorescent lights

The ballast (sometimes called control gear) is a small device wired to the light's circuitry which restricts the amount of electrical current travelling through it. Because your home's mains power has a higher voltage than the light needs to operate, the ballast gives the light a small boost of voltage to start and then just enough of a ...

Ballastless track - Superstructure :: Trackopedia

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.
