Rail Vehicle Having an Improved Cooling System and Method for Its Internal Combustion Engine

---

Abstract

---

A cooling system for a rail vehicle having an internal combustion engine as a generator of electricity is operative to exchange heat between a cooling fluid circulating in a cooling circuit connected to the internal combustion engine and air located in an underfloor space of the rail vehicle. A heat exchanger and a fan, located in the underfloor space, are fluidly connected to an exhaust in a side skirt depending from a floor of the rail vehicle. The fan is operative to force air from the underfloor space through the heat exchanger and through the exhaust to an ambient space located on an external side of the side skirt.
