At the time of the electrification of the Valenciennes-Thionville line, the single-phase current of 25 kV was introduced. Since no final decisions were made in 1952, the SNCF decided to experiment with different engine solutions by producing 4 different series of locomotives (BB 12000, BB 13000, CC 14000 and DC 14100).

The shape of all these locomotives with the two pantographs mounted above the driver's cab in the middle, the conical stems and the unusual blue paintwork of the locomotives gave all these locomotives, which were nicknamed "Iron", a coherent "look".

The CC 14000/14100 locomotives were intended for freight traffic at a maximum speed of 60 km / h, while the BB 12000/13000 locomotives were intended for mixed passenger and freight service.

Built in 20 units and ordered between January 1955 and March 1959, the 2640 kW CC 14000 were used in the north and east for heavy freight and coal trains, but were initially not very convincing due to the low reliability of the asynchronous converters and motors.

They were retired between 1977 (CC 14002, 14004, 14012 and 14017) and 1981, the last 7 machines (CC 14001, 14003, 14005, 14011, 14015, 14016 and 14018) were stationed at the Mohon depot. The CC 14018 in blue paint has been added to the SNCF museum collection. Less powerful with 1860 kW, but more numerous with 102 units, the CC 14100 were used in mining and steel transport. However, with the decline in this traffic and the increase in the speed of freight traffic, the field of application for these locomotives was gradually lost. The last 5 machines (CC 14125, 14146, 14153, 14155 and 14183) were decommissioned in June 1997.

In the course of its career, the CC 14000/14100 received some modifications, e.g. the green / yellow paintwork from November 1964 or conversions to limit the penetration of water and snow or to increase fire protection.

In order to increase the speeds in passenger train traffic, the Deutsche Bundesbahn developed the E03 series in the 1960s. The pre-production locomotives E03 001 to E03 004 were available from 1965.

These locomotives, designated from 1968 as 103 001 to 103 004, differed in several details from the series machines built from 1970.

Outwardly, the second row of fans on the series locomotives was very noticeable. The main areas of application for the beige / red painted locomotives were TEE and IC / EC traffic. From 1987 onwards, the locomotives were gradually painted in an oriental red color, with different designs being used.

In 1997 the star of the former "Starloks" of the DB began to decline. They were replaced by the BR 101. In 2003, the scheduled use of the train service ended, but the locomotives 103 001, 103 113 and 103 245, which are under the control of the DB Museum, are still used sporadically.

Starting in the mid-1990s, the famous coffee company 'KIMBO' carried out an advertising campaign on several FS rolling stock, including some ALn 668 series 3000 and 3300, customising the sides and heads with the company logo and a slogan, together with a large image of a coffee cup. 

The ALn 668 railcars were among the first to receive such advertising, initially with a red background covering the entire bodyshell and with large white lettering, later joined by a similar one with a white background and extended to other rolling stock.
