This can be achieved by internal or external expansion. Because the different firms are involved in the same stage of production, horizontal integration allows them to share resources at that level. Topics
Up until the 1990s, the average freight train in Canada was about 5,000 feet (1.54 kilometres) long and weighed 7,000 tons. But it is now not uncommon to see these trains stretch to 12,000 feet, sometimes as much as 14,000 feet (more than four kilometres), weighing up to 18,000 tons.he CN train involved in the derailment outside Brighton, for example, was built as a conventional train would be, with three locomotives in the front hauling 137 rail cars behind. But it was stretched out 8,850 feet and weighed nearly 12,000 tons.
Maximum Speed. Locomotive engines for freight are designed to shut off automatically when they reach 910 RPMs (approximately 70-75 mph). However, freight trains seldom reach that level of operation because of track conditions or speed regulations. Most trains move slower depending on the track level. For instance track 1 classification has a limit of 10 mph while level 4 tracks can support speeds up to 60 mph. For the first decade of the 21st century, freight train speed has varied between 20 and 23 mph.
