The effects of a winter environment on the design of rolling stock

CAF (Construcciones y Auxiliar de Ferrocarriles S.A.) asked Comatec to help determine what effects the Nordic winter conditions would have on the structure and systems of the tilting body trains they were tendering for use on Swedish railways. Once commissioned, the trains must be able to cope with sub-zero temperatures, ice, snow and blizzards in the often harsh northern conditions.



Comatec has previously been involved in carrying out similar winter condition consultation for the Helsinki region Sm4 local trains. In that project CAF was the train manufacturer. Comatec has also carried out similar consultation on the Sm5 trains manufactured by Swiss company Stadler Rail.
