The diesel version of the TRAXX platform was introduced with the 2E version of the TRAXX platform. In the diesel version, the fuel tank occupies the same space as the transformer in the electric versions, centrally and below the main frame members. Installed motor power is 2.2MW. The diesel and electric TRAXX locomotives share the same driver cabin and control desk, body, bogies, and drive system. The maximum tractive effort is slight reduced by 30 kN to 270 kN due to the lower power of the diesel engine.
