Longest trains
The length of a train, including the longest trains, may be measured in number of wagons 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 in the India can average nearly 2.8 km. Freight trains with a total length of three or four times that average are possible with the advent of distributed power, or additional locomotive units between or behind long chains of freight cars. 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

- 1500 m – UIC standard double length train
- 1222 m – The Bangalore–Dharmavaram goods train —The train runs between Bangalore and Dharmavaram almost every day. There is no stop for this train, and there is no railway station on this route which can accommodate the whole train on a single track or platform. Indian Railways term this as increased vehicle length. This reduces the traffic in this single-lined region; two goods train attached back to back, each train is led by two diesel electric locomotives.
- 1000 m
- * The Netherlands–Germany—trial trains of this length
- * Saudi Arabia 1000 m double stack
- 835 m — In Denmark and to Hamburg, Germany; 2 locomotives and 82 waggons.
- 800 m — RVR in East Africa 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.

- Kijfhoek–Eindhoven, Netherlands. In 1989 the ' Nederlandse Spoorwegen' celebrated their 150th anniversary. On 19 February 1989, NS ran a test with 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. Twenty years later, in 2009, Railz Miniworld repeated the stunt on a smaller scale, inside their exhibition in Rotterdam.
- Ghent–Oostende, Belgium. On 27 April 1991, one electric locomotive and 70 passenger cars held a charity run for the Belgian Cancer Fund, thereby exceeding the Dutch record.
