In today’s world, innovation is happening at an unprecedented pace in various fields, including material, technology, renewable energy, artificial intelligence, and processes, among others. It is important to not only follow a long-term vision but also to make innovations quickly available. At Alstom, we therefore differentiate between “innovation in the now” and “innovation for the future”.
This paper is part of a series of documents that explain our approach to a specific topic to deliver innovation in the now and to prepare innovation for the future.
Alstom’s interest to innovate with weight is motivated by the role weight plays on train performance, safety, and cost.
Weight vs energy consumption: Given that a significant proportion of a train’s energy consumption is linked to
rolling resistance, and how a significant portion of this is driven by a train’s weight, Alstom chooses to innovate
with both weight sensitive and energy efficient designs.
