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.
