The rail rod functions as a load that holds the weight of the train traveling on it. The large circuit weight can result in excessive friction and wear, requiring a hard, wear-resistant rail surface. The purpose of this research is to design a prototype tool which serves as an effort to increase the resistance on the rail road surface. The method used in the concept of this research is the flame hardening theory, namely heating the railroad using oxy-acetylene gas then quenching quickly to increase the hardness on the railroad surface. Prototyping begins with hardware design which includes Surface Treatment tools and designing automatic control program software. The results of the prototype were tested for the successful functioning of a tool that can be operated properly using manual mode with a maximum speed of 0.1 m/s and an automatic mode of 0.08 m/s.
