On 15.09.2011, the first three Traxx DC locomotives for Railpool left the Bombardier assembly factory in Kassel; E483 251, 252 and 253 were heading for Poland that day. 251 and 252 had logos of Lotos Kolej.
These machines were the first Traxx DC machines to be assembled in Kassel, since the outshopping of DC-prototype E483 001 in August 2006. The Italian factory in Vado Ligure had been the 'center of competence' for the DC-member of the family since then, producing all units since the 001. In Italy locomotives were built for Italy, Poland and Spain.
