Interrail's The Interrail Effect campaign

We Are Pi and social agency Butterfly Effect launched Interrail's new campaign, The Interrail Effect, on 10 September to make the case that the long route is the point. The creative turns a poster into a tiny puzzle and backs it with short, social-first travel films made by creators who actually used the pass.

Why it matters

For travellers who think of flying as the only fast, rewarding option, this campaign reframes rail as meaningful time. Interrail’s own customer research — used to shape the messaging — found that around 70% of customers said a trip changed how they see the world, and roughly a quarter said it was much more impactful than other holidays. That’s the emotional claim the brand now builds around.

The idea in one poster

The launch creative is simple and sly: a stylised map of Europe crossed by a single yellow line that reads as a train route. The route’s stops are words, and they join to form the sentence: “Realising the best bit is between here and there.” The line keeps going past the last word as a dotted, straight track — a small visual cue for open‑ended exploration.

Creators and formats

Alongside the poster roll‑out, Interrail worked with 30 creators from the US, Canada, Australia and Europe. Their short videos sit between casual social clips and glossy travel films, aiming for authenticity without feeling low‑effort. The campaign will run across paid media, organic social, EDM, partnerships and PR, plus the creators’ own Instagram, TikTok and other channels.

“The Interrail Effect isn’t something we invented.”

The campaign also tidies up Interrail’s brand architecture after a business name change earlier in the year: one unified Interrail brand now covers what had been split between Interrail and Eurail. Launch markets on 10 September included the UK, Australia and the US, with further roll‑out across Interrail’s channels planned.

It’s not a radical creative move, but the approach fits the product: a travel pass that sells itself more easily when the idea is lived and shown by people on the move. For anyone tempted to skip rail for speed, these ads ask you to notice what you might miss when you race past it.
