EN 18141:2026 - Emergency Push Button Specifications for Train Driver’s Cab

Railway applications - Braking - Emergency push button

EN 18141:2026 introduces harmonized requirements for the design, function, and testing of emergency push buttons located in train driving cabs. This standard is crucial for rolling stock safety and complies with the latest operational, environmental, and user interface guidelines.

Key sections cover the two-state function (emergency brake application demanded or not), mechanical and electrical specifications, and performance under various environmental influences (shock, vibration, temperature, humidity, corrosion, and solar exposure). The emergency push button must provide consistent, reliable actuation to initiate train-wide emergency braking safely and is distinct from emergency handles. Detailed type test and in-service assessment protocols are included, ensuring field robustness.

Key highlights:

• Unambiguous two-position actuation and mechanical linkage
• Extensive environmental resistance (shock, vibration, pollutants)
• Strict fire/smoke, insulation, and corrosion test requirements

EN 50155:2026 - Electronic Equipment for Railway Rolling Stock

Railway applications - Rolling stock - Electronic equipment

EN 50155:2026 is the definitive standard for electronic equipment installed on railway vehicles. It covers hardware used for control, regulation, protection, diagnostics, energy supply, and subsystem control (for doors, ETCS [European Train Control System] on-board functionality, and wheel slide protection). The scope includes electronic components, sensors, and semiconductor drive units linked to railway rolling stock subsystems.

The document addresses all critical phases—design, integration, operating conditions, documentation, maintenance, and repair. Notably, requirements for reliability, maintainability, hardware (printed circuit boards, insulation), software integration, and environmental robustness (temperature, humidity, shock, vibration) are specified. The document aligns with related standards, and for software development, relies on EN 50716.

Key highlights:

• Complete lifecycle requirements for electronic equipment on rolling stock
• Demanding environmental class specifications (temperature, vibration, pollutants)
• Best practices for software/hardware verification and maintainability
