Nor I, but I have an interest in various European railways and OHLE problems both self-inflicted and otherwise are not uncommon.
Apart from some of the new-build high speed lines, I can't think of any mainland lines that operate at the combined frequency and speed of the EC or WC main lines, let alone at around twice the frequency compared with when the wires were put up. Statistically that is likely to lead to more incidents being more disruptive.
BTW I spotted a report of wires damage on the GWML west of Swindon this morning, a route equipped with the latest version of OHLE (and IIRC ultra-heavy-duty at that) - it can happen anywhere
