European foreword
This document (prEN 18166:2025) has been prepared by Technical Committee CEN/CLC/JTC 20 "Hyperloop
Systems”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
Introduction
The purpose of this document is to describe and define the high-level requirements for the hyperloop concept.
The hyperloop is a new mode of transportation for high speed ground transportation and low pressure closed
environment.
These features imply to have commercial operations with passengers in conditions that never have been
considered before what leads to the need of creating new standards and requirements to influence in all the
stages of the development.
1 Scope
This document provides a general view of the most relevant requirements to ensure safety, reliability, system
automation, security, comfort, interoperability and operations of the hyperloop system used for the transport
of passengers and goods.
This document will be the basis to set the general common requirements for the hyperloop system as a whole.
2 Normative references
