Mauritania Railway iron ore train at the station in Nouadhibou.


The length of a train, including the longest trains, may be measured in number of wagons (for bulk loads such as coal and iron ore) or in metres for general freight. Train lengths and loads on electrified railways, especially lower voltage 3000 V DC and 1500 V DC, are limited by traction power considerations. Drawgear and couplings can be a limiting factor, tied in with curves, gradients and crossing loop lengths.

Conventional freight trains can average nearly 2,000 metres.[1] Freight trains with a total length of three or four times that average are possible with the advent of distributed-power units (DPUs), or additional locomotive engines between or behind long chains of freight cars (referred to as a "consist"). These DPUs enable much longer, heavier loads without the increased risks of derailing that stem from the stress of pulling very long chains of train-cars around curves.

Bulk

A BHP Billiton Iron Ore train heads out of Port Hedland on the Mount Newman railway towards Newman, Western Australia, with lead units at right, and distributed power units at left.
  • Rail gauge: 1,435 mm (4 ft 8+1⁄2 in) except where shown.
  • Australia
    • Rio Tinto—29,500 tonnes of iron ore—2.4 km, three locomotives
    • BHP Billiton iron ore typically 336 cars, 44,500 tonnes of iron ore, over 3 km long, six to eight locomotives including intermediate remote unit
    • Leigh Creek coal—2.8 km, 161 wagons and 2 locomotives.[2][3]
    • Cane tramway - 75 waggons (610 mm (2 ft) gauge) [4]
  • Brazil
    • Carajás Railway 1,600 mm (5 ft 3 in) gauge iron ore typically 330-car trains, each 3 km long.[5]
  • China
  • Mauritania—3 km[6]—iron ore from Zouérat—trains lurch violently when accelerating or braking
  • Indonesia (proposed)
  • South Africa

General

A BNSF train of loaded well cars (or double-stack cars) at Caliente, California, United States.
A Canadian National Railway double-stack container train.
Indian Railways term this as increased vehicle length (IVL). This reduces the traffic in this single-lined region; two goods train attached back to back, each train is led by two locomotives.
  • 1000 m
  • 835 m—In Denmark and to Hamburg, Germany; 2 locos and 82 waggons.[14][15]
  • 800 m—RVR in East Africa (Kenya–Uganda) to introduce longer trains, which needs longer crossing loops.
  • 750 m – Normal for mainlines in several countries in Europe.
  • 750 m – UIC standard single length train
  • 400 m – New South Wales steam era, where lengths also limited by practical length of crossing loops mechanically operated from signal boxes.

Passenger

Two DB AG ICE 3 trains combined, on the Fils Valley Railway, near Lonsee, Germany.
  • Australia – up to 99 coaches (approximately 1.2 km) on The Ghan
  • Japan - Tōkaidō Shinkansen N700 16-car trainset 404 m
  • the Netherlands – up to 15 coaches (five 3-coach NS Intercity Materieel trains combined)[16] – 403 m
  • Sweden – 17 coaches (26.7 m each plus two Rc locomotives at 15.4 m) – 484 m between Stockholm and Luleå. Sometimes charter trains are longer than that. E.g. 22 coaches, 530 m on 24-25 Febr 2012.[17]
  • Germany – two ICE 3 trains combined – 402 m
  • France – two TGV Atlantique trains combined – 476 m
  • United Kingdom, Belgium, France – Eurostar / British Rail Class 373 (20 cars multiple unit) – 394 m
  • United States — Auto Train between Lorton, Virginia, and Sanford, Florida — up to 49 cars. 4 coaches, 2 lounges, 3 diners, 6 sleepers, one transition sleeper and up to 33 autoracks.
  • United States - Ringling Bros. and Barnum & Bailey Circus trains - Longest privately operated passenger trains in the world at nearly sixty cars each. Two trains, the Red unit and the Blue unit, tour the country in an overlapping two-year cycle. Each circus train consists of around 40-45 passenger cars with dorm rooms for the circus performers and crews, four animal cars usually placed at the front of the train for a smoother ride, a dining car referred to as the "pie car," a generator car to provide power to the train, two merchandise boxcars and 15-20 flatcars carrying circus vehicles and containers.
  • India - 24 coach trains are standard for most popular long distance services, which translates into approximately 600 meters per train.
  • Canada - The Canadian transcontinental train may have 33 train cars during peak season (May to September)

The length of passenger trains generally has to match the length of platforms, especially high-level platforms. These platforms cannot always be extended to suit extended train lengths due to bridges, tunnels, pointwork, narrowing track centers and stabling yards, though "selective door opening" can help long trains stop at short platforms.

Special test runs

(These are one-off to set records)

Bulk (ore, coal etc)

  • Australia BHP Run on 21 June 2001, comprising 682 wagons and hauled by eight 6000 hp General Electric AC6000CW diesel-electric locomotives controlled by a single driver with a total length of 7.353 km on the 275 km iron ore railway to Port Hedland in Western Australia – total weight 99,734 tons[18]
  • South Africa Sishen–Saldanha, South Africa. Run on 26–27 August 1989, comprising 660 wagons, 7.302 kilometres (4.537 mi) long and a total weight of 71 765 tons. The train comprised 16 locomotives (9 Class 9E 50 kV AC electric and 7 Class 37 diesel-electric).[19][20]
  • Soviet Union The longest and heaviest freight train ran on 20 February 1986 from Ekibastuz to the Urals, Soviet Union, was carried out with the coal train. The composition consisted of 439 wagons and several diesel locomotives distributed along the train with a mass of 43,400 tonnes and the total length of 6.5 kilometres (4.0 mi).

General cargo

  • United States Union Pacific, United States. Run from 8 January – 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. Around 618 double-stacked containers were carried at speeds up to 70 mph/112 km/h. 14,059 t.[21][22]
  • United States BNSF, United States, 2010—3.03 km [23]

Passenger

  • Netherlands Kijfhoek–Breda, Netherlands. Run on 19 February 1989, as a test and publicity stunt what would become the longest passenger train in the world. The train was pulled by one 1500 V DC locomotive and had 60 passenger cars, of which only the first 14 cars held actual passengers during the run.[24]
  • Belgium Ghent–Oostende, Belgium. On 27 April 1991, one electric locomotive and 70 passenger cars (totalling 1733 m and 2786 ton, excluding locomotive) held a charity run for the Belgian Cancer Fund, thereby exceeding the Dutch record.[24]

Longest Freight Train in History

The longest freight trains in history are recorded to have been at least 3 to 5 miles long or roughly 500 freight cars to nearly 800 freight cars.
