The UK Rail network is complex with more than twenty operators managing over six thousand locations running thousands of different services and millions of products sold. The underlying systems are all being updated and KCOM are delivering the replacement Availability and Reservations Service with an engine built on top of Neo4j.
The challenge is to build a service capable of handling millions of requests per day with under 50 ms response times whilst maintaining a complex demand model to help the privatized rail companies maximize their revenue.
