Dedicated to sustainable development, Arup is a collective of 16,000 designers, advisors and experts working across 140 countries. Founded to be both humane and excellent, we collaborate with our clients and partners using imagination, technology and rigour to shape a better world.

Arup is at the forefront of transformative rail around the world, helping shape tomorrow’s sustainable travel.

Across the world and Indonesian cities, we shape and deliver major rail projects for clients in the public and private sector. Our approach combines systems-thinking, the latest technologies and decades of experience.

From a single commuter journey to a country’s wider economy, rail can transform lives, businesses and communities. And in a world trying to cope with ever-increasing demand for mobility and the effects of climate change, while adapting to rapidly evolving technology, rail is a sustainable long-term investment.

Rail projects demand a complex mix of skills and insights – from initial strategy and economics, through to engineering, people-centred design, operations and asset management. Success depends on bringing all these elements together – brilliantly. That’s why our technical expertise is always backed by sharp strategic thinking, whether we’re optimising existing assets and services, or designing whole new railways.
