The object of this research is the profile of the wheels of the 50 tons capacity coal transport train, the Babaranjang Train, which is operated by PT Kereta Api Indonesia (Persero), or PT KAI, in South Sumatra, Indonesia. The Babaranjang Train uses a wheel called as Roda Golongan DD, with a slope profile of 1:40. In this paper, it is proposed to use a more conical wheel profile to reduce the potential for derailment. Derailment, mainly caused by changes in the geometry of the wheel profile due to wear that occurs in the contact between wheel and rail surface. Research is to use rail vehicle dynamics analysis on wheel and rail contact using Universal Mechanism software. In this paper, a comparison will be made using the wheel profiles of 1:40, 1:20 and 1:10 on the Babaranjang Train. The result is that wheels with a tread profile slope of 1:20 show a 18.59% lower derailment potential than wheels with a tread profile slope of 1:40. The 1:10 wheel profile shows an even greater reduction in potential derailment than the 1:40 wheel profile, which is 40.80%. Replacing the 1:40 wheel profile with a more conical wheel profile will reduce PT KAI’s financial losses due to the Babaranjang Train derailment.
