TCDD E4000 was the first electric locomotive
used by the Turkish State Railways
, TCDD. The three units, numbered E4001 - E4003 were built by Alsthom and Jeumont
in France. The units are currently disused.

. In addition to delivery of 18 electric multiple unit
s, TCDD wanted to be able to use electrical engines instead of steam engines on long-haul trains on the last few kilometers into Istanbul.
Because the line the locomotives were to serve on was flat and did not allow high speeds, the E4000 was a simple and conservative locomotive, utilizing a direct, single phase AC motor fed directly from the transformer. But even by 1957 the development of rectifier
s directly fed AC motors obsolete. The design of the locomotives are based on Paul Arzens
of Alsthom, and resemble many of the concurrent locomotives produced by them.
