Abstract:
1. In a railroad locomotive for operation in low ambient temperature conditions with the locomotive having an engine which includes a cooling system using a coolant liquid, a coolant liquid containment system, comprising: a containment tank; an inlet port in fluid flow communication with an outlet from the engine cooling system and with the interior of said containment tank; an inlet valve for controlling the flow of coolant liquid through said inlet port; an outlet inlet port in fluid flow communication with said interior of said tank for discharge of the coolant liquid from said containment tank and out of the locomotive; an outlet valve for controlling the flow of coolant liquid from said containment tank and out of the locomotive, a sensor for monitoring a parameter indicative of the temperature of coolant liquid in the engine cooling system and generating a signal indicative of said temperature of the coolant liquid; and a control device for receiving information indicative of said temperature of the coolant liquid and in communication with said inlet valve for controlling the operation of said inlet valve and said flow of the cooling liquid into said tank, when said temperature of the coolant liquid falls below a predetermined level.
