• Source: 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.
The record-breaking ore train from the same company, 682 cars and 7,300 m (7.3 km; 24,000 ft; 4.5 mi) long, once carried 82,000 metric tons of ore for a total weight of the train, largest in the world, of 99,734 tonnes. It was driven by eight locomotives distributed along its length to keep the coupling loads and curve performance controllable.
Leigh Creek coal—2.8 km (1.7 mi), formerly ran as 161 wagons and three locomotives.
Cane tramway – 75 wagons (610 mm (2 ft) gauge).

China
Datong–Qinhuangdao railway is a dedicated coal-transport railway. Every day 50 pairs of 2.6 km (1.6 mi) long trains consisting of 210 wagons and two HXD1 locomotives use the line. Each train hauls over 20,000 tons of coal.
Shuozhou–Huanghua railway is a heavy haul freight railway that has successfully tested 30,000 ton coal trains that stretch over 4 km (2.5 mi) in April 2024. The train consists of 324 cars wagons hauled with four China Energy Investment HXD1 variants.
India
Indian Railways operated the longest train in India on 15 August 2022. The 'Super Vasuki' freight train was 3.5 km (2.2 mi) long had a total of 6 locomotives pulling 295 wagons of coal.
Indonesia (proposed)

Super Babaranjang 120 cars testing. The testing train consisted of 120 coal cars with 4 EMD G26 leading. The consist was roughly 1.7 km (1.1 mi) long.
Mauritania
Iron ore trains on the Mauritania Railway are up to 3 km (1.9 mi) in length. They consist of 3 or 4 diesel-electric EMD locomotives, 200 to 210 cars each carrying up to 84 tons of iron ore, and 2-3 service cars.
South Africa
Sishen–Saldanha railway line ore trains on 1,067 mm (3 ft 6 in) – 4.1 km (2.5 mi)
Ukraine
12,000 tonnes




General



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.
1,524 metres (5,000 ft) – France – intermediate locomotive – trial
1,222 metres (4,009 ft) – The Bangalore–Dharmavaram goods train (India)
1,000 metres (3,300 ft)
The Netherlands–Germany—trial trains of this length
Saudi Arabia 1,000 m (3,300 ft) double stack
900 metres (3,000 ft) — Babaranjang Baratarahan from Tanjung Enim Coal Mine to Tarahan Port, Indonesia. 2 or 3 locomotive and 60 to 61 coal wagons.
835 metres (2,740 ft) — In Denmark and to Hamburg, Germany; 2 locomotives and 82 wagons.
