Railway light grids

Fasnacht Dynamics AG has been manufacturing light grid systems for more than 30 years. Our specialty is railway light grids that reliably detect individual coaches and distribute them to the individual tracks at the marshaling hump so that new train components are created. Even before the marshaling hump is switched, it is important to ensure that the separations occur at the correct locations.

Coupled coaches continuously interrupt the beam during their entire transit. An uninterrupted beam means "decoupled". Each system employs two channels and is designed so that potential disturbances will never result in clearance.
