Blue Tiger locomotive was developed jointly by GE - Transportation and Bombardier, the Blue Tiger diesel-electric locomotive has an axle weight of less than 25 metric tonnes. It is available in various horsepower ratings and may use either AC or DC propulsion systems.
Initially the axle load was expected to be a light 18 tonnes and the power at 2500 kW. In practice, the German locomotives had an axle load of 21 tonnes, mass of 126 tonnes and engine power of 2,430 kW. General Electric supplied diesel engines and electrical transmission system (which utilised IGBT-based inverters driving AC traction motors).
