Curved based on Regulation of the Minister of Transportation No. 60 of 2012 Concerning Railway Track Technical Requirements has a minimum radius of 200 m, but in certain cases the curve radius can be planned to be less than the written regulations with special provisions. One of the track locations on the MRT Jakarta operating route has a radius of around 180 m, which is very interesting to discuss, especially in terms of wear which may occur greater than curves with a radius that meets the requirements in written regulations. Analysis of rail wear related to rail service life will be the main discussion. Passing tonnage will be the independent variable and time period will be the dependent variable which has the final result that the rail can still be used for at least the next 6 years.
