Next Challenge for Germany’s Vintage Rail Lines: Integrating Cybersecurity Into Workplace Safety by 2026

But a cascade of derailments, broken cables, heat closures, and now a looming IT security regulation is piling pressure on museum and park rail operators.

A new technical rule — TRBS 1115 Part 1 — took effect on 15 January 2026. It requires that cybersecurity be incorporated into occupational risk assessments. That mandate applies to museums and transport operators alike, including the small heritage lines that run on nostalgia and volunteer labour.

The new TRBS 1115 regulation requires you to incorporate cybersecurity into your risk assessments. Many employers underestimate the gaps this reveals in their current documentation. A free Risk Assessment Toolkit offers 41 ready-to-use templates and checklists — covering fire safety, manual handling, first aid, and lone working — to help you stay compliant and protect your workforce.

The rule is not theoretical. On 15 March 2024, the German Oceanographic Museum in Stralsund was hit by a massive cyberattack. Two-thirds of its systems were encrypted. While the aquariums remained safe thanks to a separate backup, the administration operated without email or telephone for weeks. Similar attacks have targeted Berlin’s Natural History Museum and the Dresden State Art Collections. Experts are now calling for significantly higher investment in IT infrastructure across the cultural and transport sector.

Collision, Heat, and Cable Failure

Tangible breakdowns continue to plague the rolling stock itself. The Döllnitzbahn suffered a severe blow on 23 June, when a locomotive collided with a lorry at a level crossing in Oschatz and derailed. The damage runs into six figures. The engine had only returned to service on 2 June after a major inspection and will now be out of action for three to four months. The disruption hits school transport between Oschatz Süd station and Oschatz main station particularly hard. The lorry driver told investigators he was distracted by a bee sting.

Technical faults also force closures. A cable defect in the train radio system shut down the line between Uelzen and Gifhorn, which only reopened for regional traffic on the afternoon of 26 June.

Heat is an equally stubborn enemy. Dresden’s park railway suspended all operations until 28 June because of extreme temperatures. The park authorities feared falling branches in the castle gardens. All events and guided tours were cancelled. Such heat-related shutdowns are becoming more frequent, creating a logistical headache for operators.

Not everyone stops. The Bergische Museum Railways are holding a regular running day on 28 June with historic trams departing from the Kohlfurther Brücke depot.

Nationwide Radio Failure Exposes Ageing Infrastructure

Behind the scenes, a nationwide disruption on the night of 24 June revealed the fragility of the German rail radio network. A routine switch replacement in the GSM-R system — which is more than 20 years old — triggered a fault that paralysed traffic for roughly two hours. A successor system will not arrive for at least another decade.

As heritage railways face new digital obligations, a systematic risk assessment is essential. Over 37,000 UK businesses already use a free toolkit that provides professional templates for all aspects of health and safety management. It saves time and ensures nothing is overlooked when documenting risks. Get the free Risk Assessment Toolkit

In response, Deutsche Bahn has temporarily suspended component swaps and now restricts maintenance work to the window between midnight and 4 a.m. Security politicians are demanding a critical review of the hardware in use to ensure long-term stability.

For heritage railways, the combination of ageing physical equipment, climate volatility, and new digital obligations means the old ways of running trains are no longer enough. Operators must now assess not only the risk of a snapped coupling or a hot axle, but also the threat of ransomware that could lock up their booking systems or signalling controls. The 2026 mandate makes that assessment a legal requirement — and one more unexpected cost for the volunteers and small companies keeping history on the rails.
