# Rail traction: Relationships

Source page: https://www.materialinsights.org/energy/e_rail_traction/links/

Every element and industry that Rail traction is linked to, and how. Each pair has its own card explaining the relationships between the two.

- [Vehicles, ships, rail, aircraft](https://www.materialinsights.org/links/rail-traction-and-vehicles-ships-rail-aircraft/): Rail traction is what rolling-stock builders sell: locomotives and trainsets with their motors, transformers and converters. In India, near-complete electrification of the network has turned locomotive demand almost entirely electric and pulled Siemens and Alstom into large localised factories. *(researched)*
