Transformers for railway

The fast urbanization, the increasing demand for mobility, and the excess of CO2 emissions are developing fast. It has never been so important to provide efficient and reliable transportation solutions consuming less energy and delivering more uptime at the lowest cost of ownership. Our purpose is to help our customers to meet their mobility demands on rail, land, water, and air, without consuming the earth.

Safer, greener, consuming less.

The future of Transport: towards a carbon-neutral vision

The global demand for transport is growing fast wherein, based on given present trends, passenger and freight transportation activities will be more than double by 2050. This growth carries with it greater energy demand, increased in carbon dioxide (CO2) emissions, and atmospheric pollutants. Rail travel has been well-matched to a world that is becoming more urbanized. 

With rail being among the most energy-efficient mode of transport for freight and passengers, the heavy reliance on electricity makes the rail sector the most energy-diverse mode of transport.

Together with Hitachi Energy and anchored by our mission, the purpose of helping our customers meet their mobility demand with green, safe, reliable, and efficient railways with low operating costs. This is how we will achieve a sustainable energy transition - globally.
