The FKC Sanford-Day brakeman car is an eight wheeled rail car with six magnetic brakes designed to provide protection against runaway trips on mine slopes due to rope breakage or loss of control. The FKC Sanford-Day is an improved version of the reliable brakeman car which has been the standard in slope mines for many years. The original sturdy mechanical design has been maintained but the control system and speed sensing have been improved to make the "FKC Sanford-Day Brakeman Car" more reliable, accurate, and safer.

Major improvements include digital speed sensing for improved sensing capability and reliability with decreased sensitivity to vibration caused by rough track conditions, an on-board PLC control that replaces old relay logic providing superior accuracy, improved reliability, simplified calibration, adjustment, and increased monitoring and annunciation capability, and improved safety and reliability through redundant speed sensing circuits which are compared by the PLC continuously. The car includes a stainless steel control panel, battery box, and car control station. The car also features a self leveling battery box for slopes to 18 degrees for longer battery life. Custom FKC Sanford-Day Brakeman Cars are available for special requirements.
