Lease company Angel Trains Cargo ordered EURO4000 freight locomotives with two different configurations. The units designated as 335 series are being built for the Spanish/Portuguese market and have 1668 Iberian gauge bogies. Other machines will have normal gauge 1435 mm bogiges and will be homologated for services in France, Belgium and Germany. First test runs to get this new sub serie homologated started in 2009.
First machine being used was Vossloh 2505, the machine re-appeared in France in June 2009. It got an French NVR-number; 92 87 0004 001-9. On 05.08.2009 the machine was spotted near Bebra, Germany, arriving in Munich on 06.08.2009. The days after that the machine was spotted in a test train with two ECR class66 diesel-electrics and two 152 series electrics of DB Schenker, one of them being the 152 005 with Claas livery. On 13.08.2009 the '4001' arrived in Belgium for test runs on lign '94' from Ath to Silly.
These test runs were performed at the end of August.
In August 2009 a second machine arrived in France, to perform trials over there. On 01.02.2010 the French rail safety authority (Etablissement Public de SÚcuritÚ Ferroviaire or EPSF) officially authorised the EURO4000 to run in France.
Both test units in Alpha colours ended up in Kiel in 2010, which were then repainted into silver and blue and sold to Beacon Rail. Europorte from France will use them now in central Europe.
