This is done in barrels or in tank containers. It is far more common to filter the harvested latex, dilute it with water and then to cause it to coagulate using substances such as acetic acid or formic acid or by means of electrophoresis. This separates the raw natural rubber from the water, forming a solid mass coagulum that is then further processed.
Freight train on the Suihua — Jiamusi Railway in YichunHeilongjiang There are four major interconnecting rail networks on the Eurasian land mass, along with other smaller national networks. Most countries in the European Union participate in an auto-gauge network.
The United Kingdom is linked to this network via the Channel Tunnel. The km Gotthard Base Tunnel improved north-south rail connections when it opened in Spain and Portugal are mostly broad gauge, though Spain has built some standard gauge lines that connect with the European high-speed passenger network.
A variety of electrification and signaling systems is in use, though this is less of an issue for freight; however, overhead electrification prevents double-stack service on most lines. Buffer-and-screw couplings are generally used between freight vehicles, although there are plans to develop an automatic coupler compatible with the Russian SA3.
See Railway coupling conversion. The countries of the former Soviet Unionalong with Finland and Mongoliaparticipate in a Russian gauge -compatible network, using SA3 couplers.
Major lines are electrified. Russia's Trans-Siberian Railroad connects Europe with Asia, but does not have the clearances needed to carry double-stack containers.

Numerous connections are available between Russian-gauge countries with their standard-gauge neighbors in the west throughout Europe and south to China, North Korea, and Iran via Turkmenistan. While the USSR had important railway connections to Turkey from Armenia and to Iran from Azerbaijan's Nakhchivan enclavethese have been out of service since the early s, since a number of frozen conflicts in the Caucasus region have forced the closing of the rail connections between Russia and Georgia via Abkhazia, between Armenia and Azerbaijanand between Armenia and Turkey.
China has an extensive standard-gauge network. Its freight trains use Janney couplers. China's railways connect with the standard-gauge network of North Korea in the east, with the Russian-gauge network of Russia, Mongolia, and Kazakhstan in the north, and with the meter-gauge network of Vietnam in the south.
India and Pakistan operate entirely on broad gauge networks. Indo-Pakistani wars and conflicts currently restrict rail traffic between the two countries to two passenger lines.
There are also links from India to Bangladesh and Nepal, and from Pakistan to Iran, where a new, but little-used, connection to the standard-gauge network is available at Zahedan. The four major Eurasian networks link to neighboring countries and to each other at several break of gauge points.
Containerization has facilitated greater movement between networks, including a Eurasian Land Bridge. North America[ edit ] Mixed freight running downhill in Caliente, California CanadaMexico and the United States are connected by an extensive, unified standard gauge rail network.
The one notable exception is the isolated Alaska Railroadwhich is connected to the main network by rail barge.
Rail freight is well standardized in North America, with Janney couplers and compatible air brakes. The main variations are in loading gauge and maximum car weight.
Most trackage is owned by private companies that also operate freight trains on those tracks. Since the Staggers Rail Act ofthe freight rail industry in the U. Freight cars are routinely interchanged between carriers, as needed, and are identified by company reporting marks and serial numbers.
Most have computer readable automatic equipment identification transponders.Container ship, oceangoing vessel designed to transport large, standard-sized containers of freight. Rail-and-road containers were used early in the 20th century; in the s containerization became a major element in ocean shipping as well.

Containerization incorporates supply, transportation, packaging, storage, and security together with visibility of container and its contents into a distribution system from source to user.
Feb 26, · Containerization is a system of intermodal freight transport using intermodal containers (also called shipping containers and ISO containers) made of weathering steel. The containers have. An intermodal container is a large standardized shipping container, designed and built for intermodal freight transport, meaning these containers can be used across different modes of transport – from ship to rail to truck – without unloading and reloading their cargo.
Intermodal containers are primarily used to store and transport materials and products efficiently and securely in the. used for international transportation under Customs seal, proposes a definition of "container" as "an article of transport equipment (Iiftvan, portable tank.
