SIST EN 14752:2020/kFprA1:2021

Overview

SIST EN 14752:2020/kFprA1:2021 is a European standard developed by CEN that specifies requirements for bodyside entrance systems on railway rolling stock. It applies to passenger access doors on newly designed vehicles including trams, metro, suburban, mainline, and high-speed trains. The standard includes both manual and power-operated entrance systems and outlines safety, functionality, and testing protocols to ensure optimal performance and passenger safety.

This document also addresses refurbishment scenarios where existing vehicles undergo door equipment upgrades as far as reasonably practicable. Notably, this standard excludes entrance systems intended solely for equipment access, maintenance, crew use, freight wagons, and emergency escape doors.

Key Topics

• Scope and Applicability: Covers all passenger bodyside doors on new and refurbished rolling stock in various rail applications, including metropolitan and regional trains.
• Door Operation Types: Differentiates requirements for manual and power-operated doors. Clauses related to powered doors do not apply to manual systems.
• Safety Mechanisms: Specifies interlock systems that prevent train movement if doors are improperly closed or unlocked.
• Signal and Control Systems: Defines conditions for door release and opening signals to ensure coordination with train operation and passenger safety.
• Testing Procedures: Stipulates testing methods to verify compliance with functional and safety requirements.
• Exclusions: Clearly states non-applicability to crew-only doors, freight wagons, and emergency escape hatches.
• Amendments and Updates: Incorporates recent modifications ensuring alignment with interoperability legislation and evolving safety protocols.

Practical Applications

Railway manufacturers, rolling stock designers, refurbishment providers, and railway operators benefit from adopting SIST EN 14752:2020/kFprA1:2021 to:

• Ensure passenger safety by implementing reliable entrance door systems that meet standardized safety interlocks and control signals.
• Achieve regulatory compliance with European directives governing interoperability and railway vehicle safety.
• Enhance operational efficiency through standardized door control mechanisms that coordinate door operation with traction and train speed.
• Facilitate maintenance and refurbishment by providing clear guidelines for upgrading existing bodyside entrance systems.
• Support diverse rail transport modes including high-speed, suburban, metro, tram, and light rail vehicles, ensuring consistency across different vehicle types.

Related Standards

• TSI (Technical Specifications for Interoperability): Relates to interoperability requirements for European rail systems, with EN 14752 addressing door systems where applicable.
• EN 45545 series (Railway Applications - Fire Protection): Complementary safety standards ensuring materials and components used in entrance systems meet fire safety requirements.
• EN 50126/50128/50129 (Railway Safety Standards): Set requirements for reliability, safety, and software controlling safety-critical systems like power-operated doors.
• EN 15227 (Crashworthiness): Supports structural safety aspects of rolling stock, complementing entrance system requirements.
• IEC 61375 (Train Communication Network): Addresses communication protocols that may interface with automatic entrance door control systems.

By adhering to SIST EN 14752:2020/kFprA1:2021, stakeholders in railway rolling stock development can ensure bodyside entrance systems that maximize passenger safety, operational integrity, and regulatory compliance across a wide range of railway applications.
