The diesel-electric locomotives will be assembled at Mapna’s plant in Karaj near Tehran using parts supplied from supplied by Siemens’ facility at Allach in Munich.

Prior to the imposition of large-scale international sanctions, which have now been largely lifted, Siemens worked with Mapna to supply 150 Bo-Bo single-cab EuroRunner ER24PC locomotives, known locally as IranRunner. Thirty of these were built at Allach in 2009-2010 and the remaining 120 units were assembled in Iran.
