Customer Experience Design

Understanding passengers is critical to designing customer experiences that attract people to use rail. To get to the heart of what is important to passengers, we walk a mile in their shoes; mapping journeys, interpreting trends, generating personas, conducting interviews, and designing scenarios to identify and solve pain points. We help you to locate and act on competitive points of difference that have the potential to deliver better, ownable customer experiences for rail services.

Depending on the insights and opportunities identified through research, design outcomes might involve the design of spaces, digital and physical products, or service blueprints to inform how facilities should be provisioned and how staff should support them. By considering every detail of the passenger journey we help you to craft customer experiences that drive engagement and improve loyalty with passengers.

Proven track record

We have been working in the rail industry since 2011, having been invited by the UK’s favourite rail operator, Heathrow Express, to transform their first-class carriage in time for the London 2012 Olympic Games. Our innovative train carriage design introduced premium single aisle seating, giving passengers a reason to upgrade their ticket on the rapid 15-minute journey between London Paddington and Britain’s busiest airport, Heathrow.

Since then, we have designed over 18 different rolling stock vehicles for CRRC Changchun Railway Vehicles Co. Ltd. and its worldwide customers, using some of the most advanced rail vehicle technologies in the world. Through a strategic partnership, we’ve been helping CRRC Changchun to raise the design quality of its passenger rail cars, including high-speed trains, maglev trains, metros, sleepers, and light rail. Most notably, tangerine and CRRC Changchun won the prestigious competition to design China Rail’s Beijing Winter Olympic 2022 high speed train, which took athletes, media personnel, VIPs and fans from Beijing to the ski centre in Zhangjiakou.
