Case Study: Rail Europe achieves 20% faster page loads and cuts tag deployments from months to minutes with Google Analytics Solutions

Rail Europe enhances page load speed by 20%, eliminates inconsistencies and saves effort

Rail Europe, a White Plains–based booking service that aggregates maps, schedules and fares for over 50 European train companies across up to 20 B2C and B2B domains, struggled with fragmented, developer‑dependent tag deployment. Multiple vendor tags and custom data needs created inconsistent tagging, slow pages, and long wait times for new measurement or marketing tags, diverting IT resources to repetitive tagging work and limiting timely, actionable data for marketers.

Rail Europe implemented Google Tag Manager and a single dataLayer/snippet to centralize and expose custom data to all tags, migrated tags into one interface, and removed unused code. Tags now load asynchronously and marketers can deploy changes in minutes rather than months. The cleanup improved page load speed by 20%, established consistent tagging across sites, freed IT to focus on core development, and enabled faster, richer analytics and remarketing.
