On-track work- or rescue vehicle
An on-track work or rescue vehicle for fire-fighting and/or the rescue of persons in tunnels or subway tubes has a drive which can be operated for at least a limited duration without ambient air. A liquid tank is arranged on the work or rescue vehicle. A fan blower with a fluid spraying device is connected to the liquid tank for producing a spray mist. The work or rescue vehicle is a traction vehicle for pulling or pushing other rail vehicles. A work or rescue vehicle of this type can move to a fire source under the protection of the spray mist blown into the tunnel or subway tube and, if required, pull or push a damaged rail vehicle from a danger zone.
