"in the UK with a 102 m span distance (good at wind speeds up to 61 mph), and in Hungary with 99 m span distances. For higher speeds, Siemens Sicat HA, good for speeds up to 350 kmh, has a span distance of 70 m. An in-between system good for ~300 kmh": are 350 and 300 kmh wind speeds or train speeds? And what happens to the British catenary if the wind is over 61 mph? Does it sway out of alignment? Fall over? 61 mph sounds to me like a low threshold.
