French rail operator SNCF spent Monday, 27 October scrambling to restore services after an overnight arson attack on signalling cables outside Valence crippled the high-speed line linking Paris and Lyon with Marseille, Nice and the Riviera. Investigators believe several separate fires were set deliberately along a two-kilometre stretch of track, destroying fibre-optic command circuits and safety relays.
The damage forced SNCF to cancel an estimated 40 TGV INOUI and OUIGO services during the morning peak, with knock-on delays of up to four hours throughout the day. Business travellers heading to technology clusters in Lyon-Part-Dieu and Sophia-Antipolis reported missing client meetings and onward flights. Logistics managers said time-critical freight riding TGV La Poste services had to be rerouted by road at short notice, adding cost and creating CO₂-heavy detours.
While emergency repair teams restored two of the four affected tracks by late afternoon, SNCF warned that residual delays would persist into Tuesday as signalling software is recalibrated and rolling-stock cycles are re-balanced.
The government has asked the préfet of Drôme to coordinate a judicial investigation for “sabotage of a transport network in organised gang,” an offence that carries a 20-year prison sentence. Transport Minister Patrice Vergriete called the incident “an intolerable attack on the backbone of French mobility” and pledged accelerated installation of flame-retardant cable ducts on high-risk sections.
For corporate mobility managers the episode underlines the importance of multi-modal contingency planning. Firms with travel-risk programmes that could switch staff to Air France’s shuttle flights or long-distance buses reported lower productivity losses than those tied exclusively to rail. Insurers also cautioned that ‘force majeure’ clauses may not automatically cover extra accommodation costs if employees ignored SNCF’s re-booking guidance.
