Bright minds

Our ability to bring together teams comprising developers, designers, infrastructure and data scientists to create a world-class experience for our customers and carrier partners is what defines us and allows us to continually innovate and maintain our superior customer experience.

Platform One

Through our agile, proprietary technology – Platform One – we are bringing together millions of routes, fares and journey times from hundreds of carriers. Platform One is the engine behind our Trainline consumer app and website, and it also powers the rail booking and retailing solutions for our partners and B2B clients such as rail carriers, travel sellers, businesses and public sector organisations. We leverage our technology, customer insight, data and scale to provide a seamless travel experience for our customers and put rail at the heart of more journeys.
