Longest trains

The length of a train may be measured in number of wagons (commonly used for bulk commodities such as coal and iron ore) or in metres for general freight. On electrified railways, particularly those using lower-voltage systems such as 3 kV DC and 1.5 kV DC, train lengths and loads are often limited by traction and power supply constraints. Other limiting factors include drawgear strength, coupling systems, track curvature, gradients, and the lengths of crossing loops.

The development of distributed power—where locomotives are placed mid-train or at the rear of the consist and remotely controlled from the lead unit—has enabled the operation of very long freight trains, sometimes exceeding in length. By distributing traction and braking forces more evenly throughout the train, this configuration allows for longer and heavier consists while reducing the risk of derailment, particularly on curves.

• Australia
  • BHP iron ore train has typically 268 cars and a train weight of 43,000 tonnes carrying 24,200 tonnes of iron ore, Template:Cvt 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 Template:Cvt 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.
  • Leigh Creek coal—Template:Cvt, formerly ran as 161 wagons and three locomotives.
  • Cane tramway – 75 wagons (Template:RailGauge gauge).
• Brazil
  • Carajás Railway Template:RailGauge gauge iron ore trains are typically 330 cars long, totaling Template:Cvt in length.
  • VLI Template:RailGauge Grain with 160 hopper cars, or 80 hoppers plus 72 FTTs (for pulp transport) totaling about Template:Cvt long.
• China
  • Datong–Qinhuangdao railway is a dedicated coal-transport railway. Every day 50 pairs of long trains consisting of 210 wagons and two HXD1 locomotives use the line. Each train hauls over 20,000 tons of coal.
• Mauritania
  • Iron ore trains on the Mauritania Railway are up to Template:Cvt in length. They consist of 2 diesel-electric EMD locomotives, 200 to 210 cars each carrying up to 84 tons of iron ore, and 2-3 service cars.

• > – United States – BNSF Railway and Union Pacific Railroad (UP) regularly operate intermodal container trains exceeding in length on main lines in the western United States. On the UP, these trains can stretch to over with 5 locomotives and 280 well cars. Trains longer than accounted for approximately 6% of BNSF's and 10% of UP's total train volume since December 2024Template:Dated maintenance category (articles). The practice has drawn criticism due to concerns about blocked road crossings, which can cause delays for motorists and impede emergency response times. Railroads have argued that longer trains improve efficiency, lower emissions, and reduce the number of crossing activations, the most likely time for a collisions between a train and vehicles. According to the Association of American Railroads, fewer than 1% of trains in the United States exceed in length.

Special test runs

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

Bulk (ore, coal etc)

• Template:Flagicon BHP ran a world record-breaking ore train on 21 June 2001 the Template:RailGauge gauge line iron ore railway to Port Hedland in Western Australia. The train comprising 682 wagons and hauled by eight Template:Cvt 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 long, with a total weight 99,734 tons, largest in the world. The train carried 82,000 metric tons of ore.
• Template:Flagicon Sishen–Saldanha, South Africa. Run on 26–27 August 1989, comprising 660 wagons, long and a total weight of 71,765 tons on a Template:RailGauge gauge line. The train comprised 16 locomotives (9 Class 9E 50 kV AC electric and 7 Class 37 diesel-electric).
• Template:Flagicon Norfolk and Western Railway unit coal train from Iaeger, West Virginia to Portsmouth, Ohio, 15 November 1967. The train consisted of 500 cars and six EMD SD45 diesel-electric locomotives distributed throughout the train for a total weight of 48,170 tons and total length of .
