European train Wi‑Fi: summary of Ookla analysis (Q2 2025)

Modern high-speed trains are widespread in Europe, but onboard digital equipment — especially Wi‑Fi — still lags behind passenger expectations. An Ookla (Speedtest) analysis compared train Wi‑Fi performance across European countries. Key findings:

• Top performers (average download on trains): Sweden ~64.6 Mbps, Switzerland ~29.8 Mbps, Ireland ~26.3 Mbps.
• Germany: sits in the mid‑range with noticeably lower Wi‑Fi speeds than the leaders (not among the top performers).
• Main issues identified: limited coverage (tunnels, rural areas), insufficient onboard hardware/network equipment, and mobile backhaul capacity constraints.

Passengers increasingly expect broadband-quality connectivity for streaming, social media and work — this puts pressure on rail operators and mobile providers to upgrade infrastructure both onboard and along rail corridors.

What can improve train Wi‑Fi?

• Upgrade onboard Wi‑Fi hardware (routers, caching, antenna systems).
• Increase mobile backhaul capacity along rail lines (more cells, faster links).
• Better handover and in-train network optimization to reduce dropouts in tunnels and rural areas.
