Case Study: Trainline achieves rapid agility and continuous delivery with Amazon Web Services

Trainline - Customer Case Study

Trainline, founded in 1997, is a leading train-ticketing website and app focused on making rail travel easier and smarter. Faced with developers spending 30–50% of their time troubleshooting, annual hardware refresh costs of about £1.2M, and weeks-long onboarding for new software and hardware, the company needed a faster, more scalable infrastructure to support aggressive growth across Europe. To meet that goal Trainline committed a year-long effort, dedicating about 25% of its technical resources to migrating and rearchitecting its platform.

Trainline moved to AWS and redesigned services into a microservices model using EC2, S3, RDS/ElastiCache, DynamoDB, Kinesis and other AWS tools, enabling continuous delivery four months ahead of plan. The migration raised availability by four percentage points, cut developer time spent on system administration by roughly two-thirds, shortened development cycles from six weeks to rapid weekly updates (over 10,000 updates in three months), and reduced environment setup from two weeks to two days — laying a scalable foundation for European expansion.
