Rail Fleet Overhaul, Rebuild and upgrade

Rail Fleet Overhaul , Rebuild and upgrade

Our facilities for rail fleet Overhaul , Rebuild and upgrade of Rail Fleet is located inside the Iran Railways 30000 Sq. meter Locomotive Rebuild factories in 1300000 Sq. meter area. Remanufacturing will increase performance and add 15 to 20 years to the life of locomotives . Locomotives are disassembled to the frame and their components are distributed throughout the shop to be qualified and replaced as needed.  Mechanical, electrical and rotating equipment parts are remanufactured using today’s finest technology.  The main frame, cab, long hood and truck frames are sandblasted, checked for wear, repaired and completely painted.

 Projects:

  • Remanufacture of 28 GE Locomotives(C30-7)
  • Remanufacture and Upgrade of 5 GE Locomotives(Converting U30C model to C30-7)
  • Remanufacture of 10 EMD Locomotives(GT26-CW)
