The high-speed and regional rail lines serving Paris-Charles de Gaulle Airport (CDG) experienced significant disruption on 4 October after an unidentified object was discovered on the tracks near the airport complex. Eurostar’s real-time French-language service bulletin reported “Retards à Aéroport Paris-Charles de Gaulle le 04/10/2026” as trains were slowed or held while maintenance teams removed the obstruction. The incident affected TGV-inOui and Ouigo services on the inter-airport line as well as the RER B suburban link that connects CDG with central Paris and major business districts such as La Défense. Several morning departures were delayed by up to 45 minutes, and at least one CDG-bound TGV from Lyon was terminated at Marne-la-Vallée, forcing passengers to transfer to shuttle buses. For international travellers transiting through CDG—including thousands of delegates heading to Paris trade fairs this week—the rail hiccup compounded already lengthy EES passport-control queues inside Terminal 2E. Airport operator Groupe ADP deployed additional staff to guide passengers towards alternative bus options, but highway congestion on the A1 limited the benefit. Mobility managers should flag the risk of rail-access interruptions when drafting arrival instructions for visiting staff. Corporate travel policies may need to budget for last-minute taxi or chauffeur services until the autumn engineering-works season ends later this month.
