German Rail Operators Urge Travelers to Avoid Non-Essential Trips as Heat Disrupts Service

Deutsche Bahn and several other rail operators in Germany are urging passengers on Saturday, June 27, 2026, to avoid non-essential travel as extreme heat puts the network under strain.

The warning applies to both long-distance and regional travel. AP reported that the advice covers not essential journeys this weekend, while WELT said Deutsche Bahn described the transport infrastructure as heavily affected by record heat.

The immediate message for travelers is straightforward: expect disruption, and if a trip is not necessary, postpone it.

National Express pauses five RRX lines

The clearest operational response so far comes from National Express. The operator said it will suspend service on five RRX lines in North Rhine-Westphalia between 1 p.m. and 7 p.m. local time.

The affected routes are RE1, RE4, RE5, RE6 and RE11.

National Express said the pause is precautionary. The company framed the move as a way to protect passengers and employees and to avoid unplanned service failures later in the day.

What Deutsche Bahn is saying

Deutsche Bahn has not announced a full shutdown of its network. According to WELT, the company plans to keep operating, even as it warns that rail service is being hit hard by the temperatures.

That distinction matters for travelers. The story is not about a system-wide closure, but about a network under unusual pressure, with operators trying to reduce risk and manage service interruptions as conditions worsen.

The warning developed over the day

The situation escalated in stages. WELT first reported early on Saturday that National Express was preparing to pause the RRX lines in the afternoon.

Later in the morning, WELT reported Deutsche Bahn's broader warning against unnecessary travel.

By early afternoon, AP was also reporting on the rail disruption in Germany and the strain on transport infrastructure. The Guardian's live coverage later updated the wider European heatwave context and again noted rail disruption in Germany.

Wider strain on transport

The rail problems are part of a broader infrastructure stress test caused by the heatwave. AP reported temperatures near 40 degrees Celsius in Germany and said some highways were buckling under the heat.

That wider context helps explain why rail operators are taking a cautious stance. The heat is affecting not just passenger comfort, but the reliability of transport systems themselves.

What travelers should expect

For passengers, the practical consequences are delays, cancellations and reduced service on some routes.

Trips that are not urgent may need to be moved to another day. Travelers with fixed plans should check their operator's latest service updates before departure and be prepared for short-notice changes.

What remains uncertain

The main open question is how far the disruption will spread by the end of the day. It is not yet clear whether more operators will announce additional restrictions or whether Deutsche Bahn will tighten its own measures.

The research packet also flags the weather outlook itself as a factor to watch, including warnings about thunderstorms and heavy rain that could further complicate rail operations.

For now, the story is a live example of how record heat is forcing rail companies in Germany to manage both safety and service continuity at the same time.
