This is a patented ballast dispensing control system that is currently in use throughout the US on every major railroad. Using a reliable data network with a precision GPS receiver, this system provides real-time control and monitoring of a ballast "train",  Individual control units contain up to 16 channels of 24 bit analog input, 32 FET driven discrete outputs, and 32 opto-isolated discrete inputs. An on-board system controller provides network and power control; satellite, cellular, and RF communication; precision DGPS reference input, and local IO for monitoring and control.
