Onboard the train you will find free WiFi at your disposal and electric power sockets commonly available on the coach. Passengers can purchase food at a buffet car with cafeteria service and light meals (except on the Alentejo line).

In 2026, the Intercidades (IC) trains operated by Comboios de Portugal (CP) do offer complimentary Wi-Fi, but the quality can be inconsistent depending on the route. The service relies on mobile cellular networks, meaning that when the train passes through rural areas, deep valleys, or tunnels—especially on the North Line between Lisbon and Porto—the signal may drop entirely. While it is sufficient for checking emails or messaging, it is often not robust enough for high-definition video streaming. For 2026 travelers, a high-value "pro-tip" is that the Alfa Pendular (AP) high-speed trains typically offer a more stable and faster Wi-Fi connection than the IC trains. If you need to work during your journey, it is wise to have an offline backup of your documents or a local SIM card with a good data plan, as the shared "CP-WiFi" can become significantly throttled during peak commute hours when many passengers are connected simultaneously.
