SWOT Hydrail - Strengths
Government support for the railway system - Turnkey base
Accumulation of technology - propulsion system, inverter, electric motor, reduction gear, battery system, super capacitor systttem etc - railway vehicles/systems by mostly national project - cost down through domestic engineering
SWOT Hydrail - Weaknesses
Fuel cell - high price - poor durability - high maintenance cost Railway is less sensitive to the change Uneasiness on the safety of hydrogen
SWOT Hydrail - Opportunities
Commercial use of FC bus and car is slow Refueling hydrogen stations are not even readyyet nationwide Need for hydrogen transportation is still encouraging Hydrogen supply and flow are not economical with bus and car
SWOT Hydrail - Threats
Current trend is diesel to electricity in railway Railway is recognized behind roadway in timeliness and urgency - railway is generally recognized as environment-friendly
FC Bus and Train
Both of them are public transportation Price portion of fuel cell system is of great advantage to train Operation condition is better on railway Hydrogen infrastructure is easier with railway
National project / Commercial use
Demonstration program for FC bus and car is underway Hydrogen production and storage are developed Commercial 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.

Safety for the use of hydrogen needs to be recognized by the general public through technical demonstration and development It doesn’t have a great impact on the deploy of hydrail just to 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.
