Increasing environmentally awareness led to the development of environmentally harmless lubricants made by biodegradable materials. Biodegradable lubricants are suitable for various kinds of application, one of the promising usages is for railways. Oils or greases are applied for railways or points to keep sufficient friction coefficient or to avoid wear damage. These lubricants are "once-through" lubricants, and never recovered but defused into the earth's surface. The oxidantion of lubricants on the railways will take place because of the sunlight effect. The solar radiation at the top of earth's atmosphere contains a significant amount of UV radiation of shorter wavelength, and therefore higher energy. This study shows that the UV-B radiation can deteriorate rapeseed oil immadiately. It is showed by the results of peroxide value, total acid number.
