General cargoUnion Pacific, United States. Run from 8–10 January 2010, consisting of 296 container cars and hauled by nine diesel-electric locomotive spread through the train with a total length of 18,000 feet (3.4 mi; 5.5 km), from a terminal in Texas to Los Angeles.
At any given time on Class Is' networks, trains stretching from 10,000 to 15,000 feet long are snaking their way to a destination. Pulling well more than 100 cars, the trains are much longer than — and in some cases more than double the size of — a typical 5,000- to 6,000-foot train.
A 150-car freight train at 50 mph needs 8,000 feet (1 and 1/2 miles) to stop; an 8-car passenger train at 79 mph needs about 6,000 feet (1 and 1/8 miles) to stop.
This is probably the closest to the actual dimensions since most cars have 2 levels, plus the Sub-Train and the wheel mechanisms underneath them. However, the scale used during the set is downscaled. According to Wilford, the train is 10 miles long (Three thousand souls stufffed into a ten miles steel tube).
As far as I'm aware, there's no legal limit. Passenger trains do not normally exceed 12 cars (around 900 feet, dependent on rolling stock type), but many are much shorter than this.
he Texas Eagle is the longest train route in the United States operated by Amtrak. Alone, the train navigates 1,306 miles daily between Chicago, Illinois to San Antonio, Texas; but three days a week, it operates with the Sunset Limited—a train route that runs between New Orleans, Louisiana to Los Angeles, California.
The Australian BHP Iron Ore is the longest train ever recorded in history at approximately 4.6 miles (7.353 km). In the Pilbara region of Western Australia, BHP owns and runs the Mount Newman railway. This is a private rail network designed to transport iron ore.
In general, freight trains typically operate at speeds ranging from 40 to 80 mph (64 to 128 km/h). However, some high-speed freight trains can reach speeds of up to 120 mph (193 km/h) on dedicated tracks.
Sometimes, the trains can stop in the middle because of technical or mechanical problems with locomotives or picking or dropping off the freight cars at the industrial tracks. They can also stop in the middle because they are waiting for the section ahead of them to get clear of a train occupying it.
Union Pacific CEO Lance Fritz said recently that he doesn't think accident data shows that long trains are riskier. But the Federal Railroad Administration cited three derailments involving trains longer than 12,250 feet (3,734 meters) where train length was a factor in its advisory.
The average freight train is about 1 to 1? miles in length (90 to 120 rail cars). When it's moving at 55 miles an hour, it can take a mile or more to stop after the locomotive engineer fully applies the emergency brake.
