Longest trains - Wikiwand

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 6 kilometres (3.7 mi; 20,000 ft) 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.

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.^[2]
  - 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.^[3]
- Leigh Creek coal—2.8 km (1.7 mi), formerly ran as 161 wagons and three locomotives.^[4]^[5]
- Cane tramway – 75 wagons (610 mm (2 ft) gauge).^[6]

General

>5,000 metres (16,500 ft) – United States – BNSF Railway and Union Pacific Railroad (UP) regularly operate intermodal container trains exceeding 5,000 metres (16,500 ft) in length on main lines in the western United States. On the UP, these trains can stretch to over 6,100 metres (20,000 ft) with 5 locomotives and 280 well cars.^[14] Trains longer than 4,000 metres (13,200 ft) accounted for approximately 6% of BNSF's and 10% of UP's total train volume as of December 2024^[update]. The practice has drawn criticism due to concerns about blocked road crossings, which can cause delays for motorists and impede emergency response times.^[15] 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.^[16] According to the Association of American Railroads, fewer than 1% of trains in the United States exceed 4,300 metres (14,000 ft) in length.^[17]
1,222 metres (4,009 ft) – India – The Bangalore–Dharmavaram goods train^[18]
1,200 metres (3,900 ft) – United States – Auto Train, an Amtrak motorail service transporting passengers and their cars between the Washington, D.C. and Orlando regions. Typical consist includes 2 or 3 locomotives, 14 passenger cars and more than 23 autoracks for transporting vehicles.^[19]^[20]^[21]

Special test runs

Perspective

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.^[25]^[26]^[27] The train carried 82,000 metric tons of ore.^[28]
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).^[29]^[30]
