Why is layover/layup heat necessary?Let's assume ambient temperature is below freezing. The interior temperature was well above freezing, when the cars were in service. The air was moist (water vapor), in part due to passengers exhaling. The water vapor will precipitate out in the form of water, as the ambient temperature within the car decreases. The water may settle in critical moving parts door mechanisms. If the water freezes, so do the doors. Therefore, it's advisable to keep car interiors at a temperature well above freezing, when not in service on cold days. The higher the temperature, the less water will condense out of the air. Less water within the car interior will mean less damage to the equipment. |
