Case Study: Danish State Railway achieves world-class reservation performance with Capgemini

Danish State Railway (DSB) - Customer Case Study

The Danish State Railway (DSB) needed a robust and advanced reservation system to manage its passenger train services. They partnered with vendor Capgemini to develop and maintain the Plads90 IT system, which would face the ongoing challenge of remaining current with rapidly changing technology while handling millions of annual booking requests.

Capgemini's solution was the Plads90 system, built on an HP NonStop mainframe and using sophisticated allocation algorithms. The system successfully handles over six million reservations a year and was adapted to support a surge in online bookings, which now account for 42% of all sales, without requiring fundamental changes. The long-term result for DSB is a stable, highly adaptable platform that has been successfully maintained by Capgemini for over 20 years and continues to be considered one of the most advanced reservation systems in its class.
