The 10 longest trains in the world

According to FRECKED, The length of a train is measured by the no of wagons containing bulk loads such as ore, oil etc. that are attached to the main locomotive. The length of a train and the load bearing capacity of the wagons can be limited on electrified rail gauges which are of a lower voltage rating such as 3000V DC or 1500V DC as they face issues with traction power. Elevation changes, curves and bends along the route, loop lengths, couplings and draw gears can also be limiting factors to the length of a train.
 Longer lengths can be achieved with the help of distributed power units, which can stretch the overall length to more than three or four times the average length, i.e. up to 8000 meters. The main advantage of using distributed power systems is that they enable much longer and heavier loads to be carried across without the risk of the train derailing from the stress of pulling these long wagons along steep curves.
Adding a locomotive in between the freight wagons also aid in pulling the wagons more efficiently with efficient weight distribution among more than one locomotive. So without further ado, here is the list of the 10 longest trains in the world.

10 The Ghan, Australia

The Ghan is a passenger train, the only one in this list runs between the cities of Adelaide and Darwin. The entire journey is of 2979 kilometers and takes about 54 hours to undertake. The train’s name honors the Afghan camel drivers who came to the country in the late 1800s and the used the train as the medium to explore the interiors if the country.
The entire carriage consists of anywhere between 16 to 26 carriages made of stainless steel on average but it once carried a total of 99 carriages which stretched the overall length of the length to around 1200 meters.

9 Maruti freight train,Plane

Launched in 2011 by the Central Railway of India, this freight train will generally operate between the routes of Bilaspur to Bhuswal. It runs at an average speed of 50 kmph and is pulled by four locomotives (two in the front and two in the middle).
The train has a load bearing capacity of about 9000- 10000 tons and comprises of 118 wagons and runs a total length of about 1400 meters. It was planned to be of longer length but issues such as driver- guard communications, sharp bends along the route and gradient changes acted as a hindrance. Nevertheless, it is one of the longest freight trains in South East Asia and the easily the longest in the country.

8 Rio Tinto Railway Services, Australia

Rio Tinto owns and operates the largest private railway network system in Australia. It has access to 15 mines with the help of mainline systems which spans over 1700 kilometers long. It has 173 locomotives and 10500 wagons at its disposal at service.
Hamersley Iron and Robe River Iron are the two organizations which frequently operate service to these mines to extract iron ore deposits. They assembled huge trains which comprised on an average of 226 wagons each with a carrying capacity of 105 tons for each of them. One such fully loaded train has a freight bearing capacity of about 30000 tons and are up to 2400 meters in length.

7 Mauritania Railway Iron ore trains, Mauritania

The Mauritania Railway is the national railway of the country of Mauritania. These trains are responsible for carrying iron ore from the mining center of Zouerate to Nouadhibou along a 704 kilometer line. Passengers rarely travel along this track on specialized passenger cars with this train but many hop along in the wagons itself!
Trains running on this railway line are up to 2500 meters in length and comprise of 3 or 4 diesel-electric EMD locomotives to pull them. There are a total of 200-210 wagons in total and the trains have a load carrying capacity of about 85 tons. It is used to transport more than 16 million tons of ore every year.

6 Daqin Railway Coal Trains, China

The Daqin Railway coal trains is used to transport coals along a 653 kilometer coal transport facility in northern China. The railway line passes through the provinces of Beijing and Tianjin and is publicly operated by a stock trading company. The track was built in 1984 with a single line but was modified to a double line in 1992 to meet growing demands.
Freight trains operating on the Daqin line can carry goods up to 20000 metric tons, the largest carrying capacity in the country. This is made possible by the use of powerful locomotive models such as the HXD1 and HXD2 which have a power output of close to 10 MW and are much powerful than the older DJ1 variant locomotives. The trains carrying coal are generally about 210 wagons long spanning a length of up to 3200 meters.

5 Cajaras Railway Freight trains, Brazil

The Cajaras Railroad is 892 kilometers long and was fist inaugurated in 1982, links the largest open pit iron ore mines in the world from the Cajaras to Ponta de Madeira Port in Sao Luis. Over 120 million tons of iron ore and 350,000 passengers travel through this railroad, which is considered as the most efficient one in Brazil.
The revenue generated by these ores contribute to a major part of Brazil’s economy. One this route a total of 10756 wagons and 217 locomotives are available for use. Over 35 different trains circulate on this route including one of the world’s largest train in regular operation, consisting of 330 wagons and a total length of 3300 meters.

4 AAR standard S-400, USA

Freights trains make up a $60 billion industry, play an important role in the country’s economy for the movement various minerals and renewable energy deposits. Most of the freight railroads are privately owned and operated by organizations, and about 15 to 20 percent of their expenditure is invested to maintain them.
One of the most popularly deployed freight trains is the AAR standard S-400 which comes with a host of safety features such as air brakes and electronically controlled pneumatic brakes equipped on the locomotives which prevent wagons it from derailing when going through sharp bends. The S-400 generally comprises of 180 wagons adding up to a total length of around 3659 meters.

3 RDP trains, South Africa

Also known as the Ore Export Line this railway line is 861 kilometers in length. Built in 1976 It connects Iron Ore mines from Sishen in the Northern Cape to Port Saldhana in the Western Cape and is primarily used to transfer iron ores and not used for transporting passengers. It is a single track with tens passing loops for trains to pass the other way.
Initial train lengths along this route consisted of electric locomotives pulling 210 wagons carrying a weight of 80 tons each. Train lengths have been increased to 342 wagons since then comprising of a total length of 3780 meters and can carry a weight of 42000 tons.

2 Double Stack Container Trains, Canada

Double stack container trains are operated by the Canadian National Railway system and with the help of multiple locomotives which bear the load bearing capacity. Up until the 1990s the length of an average freight train was about 1500 meters, which was increased significantly with the use of distributed power units.
Nowadays it is hardly uncommon to see trains which have a carrying capacity of up to 18000 tons and a length of more than 4000 meters. General cargo trains are of around 3700 meters in length and bulk trains are around 3000 meters in length on an average. The longest length of a freight train in Canada is of 4200 meters.

1 BHP Billitron Iron Ore train, Australia

BHP Billitron operates the Mount Newman railway, which is a private railway line used to carry iron ore. The length of the track runs for 426 kilometers and is Australia’s one of the longest private Railway lines. It was officially opened to be used in 1969.
The journey to cove the entirety of the track, from Newman to Port Hedland tales about 8 hours and on average 250 wagons, stretching over more than 2.6 kilometers carry the ore. But on 2001 the train broke the world record for being the heaviest and longest train the world by joining 682 wagons, carrying 82000 tons of ore in the train which spanned a total length of 7300 meters long. It ran between Yandl and Port Hedland was carried forward with the help of eight locomotive engines.
