P160 AC, and that of the planned quadruple voltage SBB locomotive TRAXX F140 MS. When Bombardier introduced the first TRAXX 2 types, the original family was also designated TRAXX 1, and the number 1 was added at the end of the type designation of first-generation locomotives still in delivery. TRAXX 2 and TRAXX 2E platforms In 2004, the basic TRAXX design was subjected to a major overhaul, with the carbody and the front redesigned to suit current crashworthiness standards, and the replacement of GTO thyristor based inverters with IGBT based inverters. The option of individual axle control in place of individual bogie control was also introduced. The coolant of the inverters and the main transformer was also changed from ester to water. The carbody design was completely standardised, by default providing a space for the mounting of a flip-disc display above the windshield, which is covered by a non-structural hood in freight versions. The bogie frame was strengthened, to allow an increase of axle loads to 22 tons. This generation of the family is also referred to as the TRAXX 2 platform, and is sometimes also indicated with a number 2 at the end of the type designations. The TRAXX carbody design and internal configuration was modified again in 2006 when the first actual Diesel-electric version was built, to provide the same layout for Diesel and electric versions. In the electric versions, the central location of the diesel engine was used for the AC transformer or the DC chokes. The weight of the component at the central location is supported on a horizontal mounting plate that fits onto the main frame using the same fixtures. This generation of the family is also referred to as the TRAXX 2E platform, the type designations themselves didn't change. The TRAXX 2E generation also included the first actual deliveries of the DC versions of the TRAXX platform. The AC version of the TRAXX 2 remained in production in parallel with the 2E versions of other types. Traxx Africa In March 2014 Transnet ordered 240 dual-voltage Traxx Africa locomotives, to be built in South Africa. The first locomotive was handed over to Transnet in December 2017, with revenue service planned to begin early in 2018. This model's appearance more closely resembles its predecessors than the European TRAXX. Production All Traxx locomotives are assembled and tested at Alstom's (originally Bombardier) plant in Kassel Germany, except the
