Frequently Asked Questions (FAQs)
1. When did railroads stop using ice reefers?
The use of ice-cooled reefers by railroads ceased in 1971. By 1980, the U.S. refrigerator car roster had dropped to 80,000.
2. How does the refrigerated railroad car work?
Refrigerated railroad cars have a customized air distribution system that ensures optimal airflow. They are designed with three air ducts in the ceiling to evenly distribute air throughout the car, maintaining a cool temperature regardless of where the freight is placed.
3. Do trains have refrigerators?
Yes, trains have refrigerated cars known as refrigerator cars or reefers. These specialized boxcars are designed to transport perishable goods at specific temperatures. Unlike insulated or ventilated boxcars, reefers are equipped with cooling apparatus to maintain the required temperature for the freight.
4. What industry was most affected by the refrigerated railcar?
The refrigerated railcar revolutionized the meatpacking and agricultural industries by expanding the market for fresh produce. It provided a means to transport perishable goods over long distances, opening up new opportunities for these industries.
5. Do trains have trouble with ice?
Trains can face difficulties when operating on icy tracks. Just like driving on icy roads, acceleration and braking are more challenging due to the lack of friction between the steel wheels of the train and the steel rails. This can cause wheels to slip, making it harder to control the train's speed.
6. How much does a refrigerated railroad car cost?
The cost of a modern refrigerated railroad car can range from $30,000 to $50,000, depending on its size and features. The price may vary based on the specific requirements and specifications of the car.
7. How are refrigerated containers powered on trains?
Refrigerated containers on trains are powered by diesel-powered power packs. These power packs, with capacities ranging from 200 to 500 KVA, are installed in the empty containers that are part of the train formation. They generate electric power, which is then transmitted to individual reefers through cables running along the wagons.
