a mobile train ticket counter


Trainline is Europe's leading independent train ticket retailer and train travel app. They sell tickets to customers worldwide, enabling more than 125,000 journeys every single day in and across 24 countries, covering 87 different rail carriers.

simplabs' team worked closely with Trainline’s in-house engineering team and helped them build and extend a mobile site to accompany the existing desktop app.


It has been an absolute pleasure to work with simplabs. Their team of experienced JavaScript engineers quickly slotted in to our in-house development teams. Their expertise with modern, agile software development best practices and tools meant they were able to work with our processes to deliver fantastic customer experiences.

Mark Holt, Trainline CTO

simplabs spearheaded several engineering efforts focussed around mobile performance, improved load times, server side rendering and localization. We helped establish modern and idiomatic practices for developing mobile apps and helped Trainline's in-house engineering team internalize those through code reviews.

In addition to supporting Trainline with engineering resources and expertise, we were able to help improve the engineering process by establishing and solidifying a sprint based approach. This resulted in more efficient prioritization and a better sense of progress by both engineers and management.
