What is BS EN 14067‑4 about?
BS EN 14067 is a series of the European standard on railway tracks that addresses the topics of aerodynamic loadings and resistance to motion.
BS EN 14067‑4 is the fourth part of the BS EN 14067 series of documents that deals with requirements, test procedures, and conformity assessment for aerodynamics on an open track.
BS EN 14067‑4 refers to rolling stock and infrastructure issues.
NOTE: BS EN 14067‑4 does not apply to freight wagons and applies to railway operation on gauges GA, GB, and GC according to EN 15273.
Who is BS EN 14067‑4 for?
BS EN 14067‑4 on aerodynamics is useful for:
- Railway engineers
- Mechanical engineers
- Manufacturers of railway rolling stock
Why should you use BS EN 14067‑4?
The train aerodynamics are related to aerodynamic drag, pressure variations inside the train, train-induced flows, crosswind effects, ground effects, pressure waves inside the tunnel, impulse waves at the exit of the tunnel, noise, and vibration, etc.
BS EN 14067‑4 provides requirements on locomotives and passenger rolling stock in order to describe and limit the train-induced aerodynamic pressure loads.
BS EN 14067‑4 provides guidance on infrastructure i.e., flat structures parallel to the track and beside the track.
Methods and test procedures are given to assess train-induced pressure variations and airflow besides the track, aerodynamic loads in the track-bed, and resistance to motion.
Overall, BS EN 14067‑4 specifies standardized test and assessment methods to overcome aerodynamic loadings and resistance to motion of trains running on an open track that help you ensure safety and stability of the train as well as its functioning in case of failure or accident.
