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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

Introduction
Light rail transit (LRT) has been used as convenient urban public transportation in cities for over
100 years, due to its smooth acceleration and deceleration performance, good ride comfort and larger
passenger capacity than bus vehicles. Although LRT has high energy efficiency and operation stability,
as well as producing zero emissions, it has shortcomings. Conventional LRT is powered with electricity
supplied from the outside of vehicles through catenaries and pantographs. Setting up catenaries and
substations calls for considerably high capital cost and long construction times, and spoils urban views.
The voltage of electricity depends on power grids and service lines, resulting in poor interconnection
in rail service networks by LRT. If the grid power fails, services are suspended on all LRT lines. LRT
equipped with energy storage using batteries and super capacitors is available, but the working
distance in relation to charging time is not long enough for commercial services.
Fuel cell light rail transit (FC-LRT) solves such problems with conventional LRT. Normally, hydrogen
fuel cells are adopted as power sources for FC-LRT. It is not necessary to equip rolling stock with
pantographs, hang catenaries or install substations, resulting in preservation of the urban view and
open skies. The elimination of the facilities leads to reduction in construction and maintenance costs
and time, and also safety improvements, especially on the risk with high-voltage grids exposed in
cities. Fuel-cell-powered vehicles emit no GHGs or small particles, only water. LRT vehicles with energy
storage, which do not rely on grids for power supply, can run on tracks independently of voltage,
whether electrified or not, wherever the track gauges are the same. The on-board power source makes
LRT highly resilient, especially when the power grid fails. Fuel cells enable LRT vehicles to run for
longer distances than possible with other on-board energy storage.

Smart community infrastructures — Smart transportation
using fuel cell light rail transit (FC-LRT)
1 Scope
This document specifies a procedure to introduce smart transportation into cities by means of fuel
cell light rail transit (FC-LRT). This service contributes to a cleaner atmosphere, with zero emission of
greenhouse gases (GHGs) and small particles, an urban view free of catenaries and easy installation of
LRT transportation operations, providing safe and comfortable rides for citizens.
