# Longest trains

The length of a train 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 and power considerations. Drawgear and couplings can also be a limiting factor, along with curves, gradients and crossing loop lengths.
Very long freight trains with a total length of 3 km (1.9 mi) or more are possible with the advent of distributed power, or additional locomotive units between or behind long chains of freight cars (referred to as a "consist"). Additional locomotive units 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

* Australia
** BHP iron ore train has typically 268 cars and a train weight of 43,000 tonnes carrying 24,200 tonnes of iron ore, 2.8 km (1.7 mi) long, two SD70ACe locomotives at the head of the train and two remote controlled SD70ACe locomotives as mid-train helpers.
*** BHP used to run 44,500-tonne, 336-car long iron ore trains over 3 km (1.9 mi) long, with six to eight locomotives including an intermediate remote unit. This operation seems to have ceased since the trunk line was fully double tracked in May 2011.

* 6,100 metres (20,000 ft) – United States – a June 2024 third-party study over 10 days in Arizona found that Union Pacific routinely runs intermodal trains of more than 5,500 m (18,000 ft) in length, of which the longest was a 6,100-metre train (20,000 ft) carrying 506 containers in 280 well cars.
* 4,300 metres (14,000 ft) – United States – According to the Association of American Railroads, "Fewer than 1%" of trains in America are longer than 14,000 feet.
* 1,222 metres (4,009 ft) – The Bangalore–Dharmavaram goods train (India)
* 1,000 metres (3,300 ft) – Saudi Arabia 1,000 m (3,300 ft) double stack
* 835 metres (2,740 ft) — In Denmark and to Hamburg, Germany; 2 locomotives and 82 wagons.

## Special test runs

These are one-off runs, sometimes specifically to set records.

### Bulk (ore, coal etc)

* BHP ran a world record-breaking ore train on 21 June 2001 the 275 km (170.88 mi) 1,435 mm (4 ft 8+1⁄2 in) gauge line iron ore railway to Port Hedland in Western Australia. The train comprising 682 wagons and hauled by eight 6,000 hp (4,500 kW) General Electric GE AC6000CW diesel-electric locomotives controlled by a single driver. The eight locomotives were distributed along its length to keep the coupling loads and curve performance controllable. The total length of the train was 7.352 km (4.57 mi) long, with a total weight 99,734 tons, largest in the world. The train carried 82,000 metric tons of ore.
* 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 on a 1,067 mm (3 ft 6 in) gauge line. The train comprised 16 locomotives (9 Class 9E 50 kV AC electric and 7 Class 37 diesel-electric).
* Norfolk and Western Railway unit coal train from Iaeger, West Virginia to Portsmouth, Ohio, 15 November 1967.
