Railway applications — Rail project planning process — Part 2: Conditions

ISO/TR 21245-2:2016 aims to identify basic conditions of rail projects, which are essential input for the design of rail systems. This document does not interfere with existing national and local laws, legal requirements and regulations. It considers only the "planning stage" of rail projects and does not deal with the "execution stage". Any type of rail projects is intended to be dealt with, such as building a new line, retrofitting or upgrading of existing lines and change of operation or maintenance. In ISO/TR 21245-2:2016, conditions are dealt with as premises or constraints, which can be difficult to adjust or change by stakeholders concerned in the project.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
Railway represents an efficient transport mode to overcome societal and environmental issues, such
as economic growth, road traffic congestion, pollution emission reduction, accessibility, and so on.
Therefore, rail projects can provide great benefits for people all over the world. However, desired
outcomes cannot always be gained, since all rail projects are influenced by many factors and external
conditions as well as by stakeholder’s expectations. It therefore requires time and funding to identify
conditions and translate stakeholder’s expectations into specifications and requirements.
Expectations and conditions can be common or different among projects. These need to be identified,
analysed, prioritized and taken into account while advancing the project. If not, it is possible that the
project will not produce the expected
