Sammanfattning:
In Sweden, the winter of 2009-10 was especially severe, with cold and snowy conditions. Regardless of the weather, train operators must ensure the maximum availability of their vehicles with a minimum of risk and downtime. To this end, important tasks are to maintain high wheel quality, reduce wheel wear and ensure a steady supply of new wheels. This paper studies the problems created by severe weather, with a focus on wheel damage. It found an increase in wheel damage and wheel maintenance which put a great deal of strain on the workshops responsible for wheel turning and supplying fresh wheels. The study confirms a relationship between temperature and wheel wear and suggests the influence of the train
brake system on wheel damage in cold weather.
