For the HellasSprinters, body design of the classc EuroSprinter was directly adopted, with only small adjustments. The 120 series does not have rear mirrors, the cab side windows have a different shape, the machines have two top head lights and only six grids on top of the machine remained. The machines are painted in a assymetrical livery, resulting in a different look for each cab. The machines were delivered with white service numbers and old style OSE logos.
The 24 machines of the second serie, were built in Muncih next to ES 64 F4 series for Siemens Dispolok, the 189 series for Railion, and EuroRunner diesel electrics. This illustrates the fact that the Siemens product portfolio had eveolved since the production of the first batch for OSE. Electrics with the 'classic' EuroSprinter body design were no longer a part of the program. Still, the OSE demanded that the second batch had to be identical with the first one. At that moment the ES 64 U2 platform would be the most obvious platform to use for a 25 kV AC locomotive. Operating 30 similar locomotives was considered being more important than gaining profit from the technical progress made in previous the years. The similarity demand was applied very strictly, illustrated by the fact that the newest machines still carry little product shields on their carriages saying „Siemens Krauss Maffei Lokomotiven GmbH“, the company name of the manufacturer that was valid in 1997, but disappeared in 2001! Siemens had to restart the production of the older technical equipment again, including 'Verschleißpufferbohlen' and analogue instruments for the driver tables.
Finally, the only differences to the previous serie were found in the livery of 120 007-030, resulting from the introduction of a new corporate identity for OSE including a new numbering system. 120 007-030 were delivered with new blue-silver painted OSE logos.
The first machine, 120 007, was outshopped and transported to Greece in August 2004. Along the way, the machine was weighed in the workshops of Linz before continuing its journey. This procedure was repeated for the complete serie. In November 2005 the production of the serie was completed with the completion of 120 030.
