One of Germany's busiest stretches of railway was brought to a standstill by fire, and now a radical group has stepped forward to say the blaze was no accident. In an online statement, a collective calling itself Kommando Angry Birds claimed responsibility for planting incendiary devices in trackside cable ducts north of Leverkusen, targeting the arteries that keep trains running between Cologne and Dusseldorf.
The disruption began on Friday, when a fire broke out along the line and forced an immediate closure of the affected section. Because the damage struck the cabling that carries signals and power rather than the rails themselves, the effect rippled far beyond the point of the attack, freezing services on a corridor that thousands of passengers and freight movements depend on every day. Restoring that kind of severed nervous system is slow and painstaking work.
How the attack was carried out
According to the claim, the saboteurs did not act at a single spot. The statement described incendiary devices placed at two separate locations in the cable ducts that run alongside the track, a method designed to maximise the damage and complicate any quick repair. It is a low technology approach that requires little more than access to the trackside and a willingness to break the law, which is part of what makes it so hard to guard against across a network stretching for thousands of kilometres.
Security officials are treating the claim as credible and have opened a broad investigation into the deliberate disruption. Cable ducts sit in the open along vast lengths of the railway, far from stations and cameras, and that exposure is exactly the vulnerability the attackers appear to have exploited. Proving who lit the fires, and stopping the next attempt, is a far harder task than acknowledging that the sabotage took place.
