Transportation Geography and Network Science/Freight rail networks

Freight rail networks are one of the networks transport goods by using railway networks.

U.S.
America railroads started to build 190 years ago and have become an essential part of America’s development.

Why choose freight rail?
Rail freight can make sure that a number of cargos can be hauled at the same time while shipping. It can transport goods as many as they can to reduce the cost. Rail transportation can ensure that goods are transported in a single batch of trucks. Furthermore, rail can provide the most cost-effective cost mode to ensure that goods can be delivered if it needs to be transported for a quite long distance. Besides, different goods such as cars, manufacture goods, and flowers can be transported at the same time rather than transporting them separately. Flexibility is also the main choice for rail transportation. This is because the railway network can cover the furthest countries, and it is possible to transport trucks to all parts of the world by truck. Rail freight transportation can ensure that the goods can be delivered to those areas which have the most convenient location of delivery as possible because some areas are way too far and have poor infrastructure such as roads for other types of transportations to develop. Meanwhile, during transportation, safety is a crucial factor to be considered. Rail transportation is regarded as the safest way to ship goods since railways are safe and containers can be provided to protect the goods so that theft can hardly happen. == Freight train names == Unlike the passenger train, the freight train is hardly ever named.

Freight railway network developed in America
America’s first railroad was built in 1830. Nowadays, there are almost 140,000 miles of freight routes in operation. The U.S. freight rail network is widely regarded as the largest, safest, and most cost-effective freight system in the world. On the seven Class I railroads, they produce nearly $80-billion freight rail industry. It provides more than 167,000 jobs in the United States and provides side benefits that other modes of transportation cannot provide, including reduced road congestion, fatalities on highways, fuel consumption, greenhouse gases, logistics costs, and public infrastructure maintenance costs.

The technology used in freight rail networks
=== Innovative “Ears” === For a long time, ultrasound technology is used in freight railroads to examine the track whether it is health, like the way a doctor examines the health of a human body. This technology helps people to test the track where they cannot find by their bare eyes before the dangerous happens during the transport. Although ultrasonic technology has been proven to be effective, rail freight researchers have recently questioned whether they can further improve safety by listening to (rather than just looking for) track defects. When a train travels on any section of the track, energy is transmitted from the train through the track to the underground. These energies can be measured as a series of sound waves, which are collectively called acoustic features. The acoustic characteristics of the track depending on the health of the track. In 2013, scientists installed fiber optic cables next to the test track of an industry test facility in Colorado. As the train ran overhead repeatedly, they began to listen to the sound characteristics of the track. The track is designed to break the rules, and once it is done, the experts will get the data they need. Specifically: the sound characteristics of a healthy track, the sound characteristics of a broken one, and the sound characteristics of a nearly broken.

Sci-Fi “Eyes”
In recent days, railroads can be monitored from the sky. This cannot be imagined in the past 20 years ago. For example, the BNSF Railroad Company flew unmanned aerial vehicles or drones on tracks in parts of Texas and Oklahoma and installed high-definition video cameras, which were flooded several years ago. Security experts monitored the drone's video input to see exactly where the rails were washed away and to check the condition of the iron bridges, some of which were hit by debris. By identifying the location of the damage, BNSF was able to safely deploy employees after the flood receded and quickly restore the safe operation of the railway line. Today, Class I railways across the country are deploying drones for various safety and environmental purposes. In remote areas, drones are used to explore thousands of miles of tracks to ensure that freight trains continue to safely traverse this unforgiving terrain. Drones are also used to test air quality to ensure compliance with federal and state environmental regulations, and to inspect bridges and telecommunications infrastructure.
