Railway applications - Infrastructure - Demountable machines, trailers and associated equipment - Part 2: General safety requirements
This document specifies the general safety requirements for demountable machines and trailers, including road-rail trailers - henceforward referred to as ‘machines, for use when travelling and working on railway track.
NOTE Trailers, including road-rail trailers, are considered as machines because they are moved along the track by powered machines.
This document specifies the requirements to deal with the common hazards presented by their use on the railway during transport, assembly and installation, commissioning, travelling and working on track, use including setting, programming, and process changeover, operation, cleaning, fault finding, maintenance and de-commissioning of the machines and associated equipment when they are used as intended and under conditions of misuse which are reasonably foreseeable.
These machines will not run on railway lines open to normal traffic.
NOTE Other rail mounted railway maintenance and infrastructure inspection machines are dealt with in other European standards, see Technical Report CEN/TR 17498:2020.
This document is also applicable to machines and associated equipment that in working mode are partly supported on the ballast or the formation.
The requirements in this document are based on the assumption that the machines are used, operated and maintained by skilled person(s).
This document does not apply to the following:
- requirements for quality of the work or performance of the machine;
- use of separate equipment temporarily mounted on machines;
- machines that utilize external power supplies such as the overhead contact line system for traction purposes or as a power source;
- hazards due to air pressure caused by the passing of high-speed trains at more than 200 km/h;
- operation subject to special rules, e.g. potentially explosive atmospheres;
- hazards due to natural causes, e.g. earthquake, lightning, flooding;
- working methods;
- operation in severe working conditions requiring special measures, e.g. corrosive environments, contaminating environments, strong magnetic fields;
- hazards occurring when used to handle suspended loads which may swing freely.

Overview
SIST EN 15955-2:2025 - "Railway applications - Infrastructure - Demountable machines, trailers and associated equipment - Part 2: General safety requirements" defines the general safety requirements for demountable machines and trailers (including road‑rail trailers) used when travelling and working on railway track. It covers the full lifecycle: transport, assembly/installation, commissioning, travelling and working on track, setting/programming/process changeover, operation, cleaning, fault finding, maintenance and de‑commissioning, including reasonably foreseeable misuse. Trailers are treated as machines when moved on track by powered equipment. The standard assumes use by skilled personnel and excludes machines intended to run on lines open to normal traffic.
Key topics and technical requirements
SIST EN 15955-2:2025 addresses core safety hazards and prescribes measures across many technical areas, including:
- Hazard identification & categories for demountable machines and attachments partly supported on ballast or formation.
- Derailment safety and dynamic track testing (different requirements by maximum travelling speed: v > 60 km/h, v ≤ 60 km/h).
- Stability and overturning prevention, stationary stability proof, stability in working mode and load‑moment control with display.
- Machine structure & frame design rules (different provisions for machines with v > 30 km/h and v ≤ 30 km/h), lifting/jacking points, ROPS and FOPS.
- Rail gear, wheel suspension and inter‑machine couplings specifics for safe on‑track movement.
- Braking systems (including holding on gradients and remote brake application).
- Operator ergonomics and cabs: visibility, minimum dimensions, emergency exits, environmental protection, noise and vibration mitigation.
- Access, egress, seats and fall protection, walkways and working platforms.
- Controls and safety‑related control systems, start/stop, inadvertent activation prevention, movement controls, emergency stopping devices.
- Electrical systems & EMC, batteries, overhead contact line considerations and antenna/pantograph interfaces.

document harmonized with the European Machinery Directive 2006/42/EC.
Part 1 specifies requirements for approval of the machine for use on the railway. Depending on the
decision of the Infrastructure Manager, Urban Rail Manager or the requirements in National rules the
assessment of conformance could be undertaken by the Infrastructure/Urban Rail Manager concerned,
by a third party assessor or by the manufacturer as a declaration of conformity.
Part 2 specifies requirements for the machine to be declared conformant by the manufacturer, except in
the case of machines classified under Annex 4 of the Machinery Directive, which require a conformity
check in conjunction with a notified body.
