The Refrigerated Car

The refrigerated car was first invented in 1868 by Charles Hamilton Davis. It had horizontal air passages that extended the length of the car, dead-air chambers and circulating air to cool them. Davis’s version was a prototype, but it failed to live up to its potential. The shifting meat hanging racks made the original model impractical and dangerous to use. To improve upon Davis’s design, Gustavus Swift hired engineer Andrew Chase.

The new TrinityRail reefer is a hybrid model with an extra-strength aluminum platform for increased payload capacity. Its interior was stretched to 72 feet, an increase of about 20 feet from the standard shipping car. The new models also feature global positioning systems, which allow customers to track each car’s location and temperature. The new model’s floor is thinner and offers an additional 150 square feet of storage space.

รถห้องเย็น were first used in the meat-packing industry. In California, fruit growers organized association cars for shipping. The idea was later applied to the meat-packing industry in Chicago. A few years later, a mechanical reefer was a viable alternative to the traditional refrigerated car. The original fruit growers’ express company used gasoline-powered cars to transport citrus fruit. After the war, they began using diesel-electric locomotive technology. They replaced the gasoline engines with an alternator powered by a diesel engine.

Trinity’s refrigerated car plant was idled for some time while it converted to a new model. The company also offered temporary positions to its employees. After the transition, the company made the final decision to invest $5 million in the new refrigerated car plant. The plan to produce four cars a day meant hiring another 100 employees and a new generation of skilled tradesmen. With demand for refrigerated car transportation increasing, Trinity began looking for ways to increase production levels.

The refrigerator car was used on trains as far as 1880, but it was not common for railroads to use the cars until the early 20th century. Swift teamed up with the Grand Trunk Railway, which then transports cattle east through Canada. At the time, the Grand Trunk Railway was not generating much revenue from live cattle, so they were not shy to use Swift’s refrigerated car trains. Later, they were used by the Erie and Lackawanna Railroads to reach the Northeast.

The invention of the refrigerated car was not without risk. First developed by William Davis, the refrigerated boxcar had a compartment at the top that contained ice. It was a breakthrough in shipping perishable goods by rail. It also required the installation of icing stations at regular intervals. Additionally, the railroad had to have reliable scheduling and marketing systems to keep the cargo fresh. The refrigerated car was soon in widespread use.

In addition to transporting produce, the refrigerated car also transported beef. In 1939, the railroads received nearly 35,000 carloads of fresh vegetables and fruits in Boston alone. Ten thousand of them came from California, eight hundred and twenty-four from Florida, and one thousand and ninety-four from Texas. That is a huge difference from the days when the railroads were the primary means of transportation. If you have ever wondered how fresh beef was shipped to your doorstep, refrigerated rail cars could save you time and money.
