Overview
EN 16186-5:2021/FprA1 - published by CEN - specifies external front and rear visibility conditions from driver’s cabs for tram vehicles and describes the associated assessment method. The standard applies to vehicles operating on tram networks and sets out how to assess what the driver can see from the cab (front, rear and side). The amendment (prA1) updates scope wording, adds key definitions (including tram-train), and permits technical devices (e.g., mirrors) where a direct line of sight is not possible.
Key topics and requirements
- Scope: Defines applicability to tram vehicles on tram networks; the draft amendment removes the prior exclusion for tram-train operations, clarifying the standard applies to tram‑trains operating on tram and suburban networks.
- External visibility assessment: Specifies assessment methods for front, rear and side visibility from the driver’s cab and the conditions to be met for safe operation.
- Line-of-sight definitions: New definitions added - direct line of sight, indirect line of sight, on sight driving operation, tram-train, and external side visibility - to standardize terminology used in assessments.
- Use of technical devices: Where a direct line of sight to a detection object (for example a cylinder used in visibility tests) is impossible, technical devices such as mirrors are permitted, provided the device meets the design requirements referenced (see Figures 4 and 6 in the standard).
- Driver ergonomics and signal visibility: Annex updates clarify sight points for different driver statures (note explaining Point A for tall drivers and Point B for small drivers to ensure visibility of high and low signals).
Applications and who uses it
This standard is practical for:
- Tram vehicle designers and manufacturers - to ensure cab glazing, sightlines and optional mirror systems meet visibility requirements.
- System and vehicle integrators - when validating vehicle fit for operation on tram networks (including tram‑train services).
- Railway safety assessors, testing laboratories and type-approval bodies - for formal visibility assessments and compliance checks.
- Operators and infrastructure managers - to evaluate operational procedures tied to on‑sight driving and to inform platform/signal placement.
