• Using advanced AC system• Advanced inverters with Skiip Semikron IGBTs• Recovering brake energy by regenerative

braking• Noise-less especially at stand still and idle times• Diesel generator downsizing from 1000 kVA to

50 kVA• Better maneuver especially when the direction is

changed• Cost saving up to $700,000 / Locomotive• Possibility of using the old system chassis and

converting that to a very efficient modern system• Cruise control option outside the station yard• Able to carry 10 wagons with 400 Tons pay load• Up to 60 km/h at zero slope

• Prototype is built and tested • More powerful Hybrid Locomotives

are Designed (Up to 2000 HP) • Proposal is sent to Railway system

to built 50 locomotives by overhaul the old G12 locomotives

• Can Hybridize the line locomotives that bring 15% saving in the diesel fuel consumption and 2000 HP power boost for 4000 HP Alstom Diesels

• Hybrid Technology• Advanced AC systems• Plug in Hybrid• Up to 80% fuel savings• Up to 80% emissions reduction• 30% price of a normal

locomotive• Regenerative braking• Downsized diesel engines



صنعت خودرو


• Shunting Locomotive for Stations

• Line locomotives • GM plans to change all

locomotives to hybrid and 15% saving in the main line locomotives



صنعت خودرو


• Railway stations and their contractors for passenger and load transportation

• All private companies that deliver goods by trains

• Steel manufacturing Plants • Iron ore mines



صنعت خودرو


• Traction Motors from Overseas• Inverters can be home build• Old chassis are available• Controller and control

localized• Training• Joint venture with wagon

Manufacturers



صنعت خودرو


• Functional tests are approved by Iran Railway System

• Field tests are done



صنعت خودرو


• Around $300,000 for each locomotive if 50 locomotives are ordered

• Compared with $1 Million for similar locomotives bought from overseas

• Our own know how• Possible export capabilities by a joint

venture with Wagon manufacturing companies

• 240,000 liters/Year Diesel Fuel and $50,000 /Year Spare Parts Saving for each shunting locomotive



صنعت خودرو


• Wagon manufacturers can support the after sales services

• All electric components and soft wares can be localized

• All inverters and DC/DC converters can be built

• Wagon manufacturers can built or overhaul the chassis
