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.

described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the

different types of ISO documents should be noted. This document was drafted in accordance with the

editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).

ISO 37164:2021(E)
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.
