SWOT Hydrail -SWOT HydrailStrengths
Government support for the railway system- Turnkey baseTurnkey base
Accumulation of technology- propulsion system, inverter, electric motor,
reduction gear, battery system, super capacitor t tsystem etc- railway vehicles/systems by mostly national
projectproject- cost down through domestic engineering
SWOT Hydrail -SWOT HydrailWeaknesses
Fuel cell- high price- poor durability- high maintenance cost
Railway is less sensitive to the changeRailway is less sensitive to the change
Uneasiness on the safety of hydrogen
SWOT Hydrail -SWOT HydrailOpportunities
Commercial use of FC bus and car is slow
Refueling hydrogen stations are not even ready yet nationwidey yNeed for hydrogen transportation is stillencouragingencouragingHydrogen supply and flow are not
economical with bus and car
SWOT Hydrail - ThreatsSWOT Hydrail Threats
Current trend is diesel to electricity in railwayrailwayRailway is recognized behind
roadwayin timeliness and urgency- railway is generally recognized as- railway is generally recognized asenvironment-friendly
FC Bus and TrainFC Bus and Train
Both of them are public transportationBoth of them are public transportation
Price portion of fuel cell system is of great advantage to trainOperation condition is better on railwayOperation condition is better on railway
Hydrogen infrastructure is easier with railway
National project / CommercialNational project / Commercialuse
Demonstration program for FC bus and car is underway
Hydrogen production and storage are developed
Commercial use of the development is strongly askedCommercial use of the development is strongly asked
Bus service is operated by private companies. Even if FC
bus are financially supported with the part of purchase cost
by government, additional costs for repair and maintenance
as well as durability are still unsatisfactory.

Approach to Commercial UseApproach to Commercial Use
Safety for the use of hydrogen needs to be recognized by the general public through technical demonstration and developmentdevelopment
It doesn’t have a great impact on the deploy of hydrail just
to build a railway car/locomotive/shunterto build a railway car/locomotive/shunter.
With infrastructure of hydrogen and transportation on the
cutting edge, public railway transportation service needs to be
provided as a package.
An optimum site with the package project to realize the
hydrail service is proposed.y
