The locomotives are essentially a rebuild/modernisation of the
CFR Class EA that were built from the mid 1960s to the early 1990s by the
Craiova locomotive works. Starting with the mid 1990s, it was decided to rebuild a number of locomotives, a number of them being modernised between 1998 and 2002 by Siemens-Secheron, resulting in
CFR Class 45. The project however was stopped and it wasn't until 2006 when PROMAT and Softronic decided to rebuild a number of locomotives for freight use. Starting in 2007, the passenger locomotive modernisations began as well, but only by Softronic. Modernisation continues, but it is uncertain if it will be stopped or continued as only a small number of locomotives have been modernised in the past years. == Operation ==
