It's strange, we admit. But there is an explanation.
It’s a commonly asked question: why does Eurail still offer paper train passes when modern technology offers E-ticketing directly from your cell phone, laptop, or tablet?
Simply put: because it’s the only way to get you anywhere you want to go. All 28 countries that the Eurail Pass gives you access to have different systems for train ticketing. A paper pass can be easily used in all countries and across multiple train companies.
