In the late 1980s and early 1990s, Lengiprotrans carried out the electrification of the Cherkezkei - Kapykule railway section in the Republic of Turkey on the border with Bulgaria. It was the last non-electrified section on the line from Ankara to Europe.

The project was developed according to Turkish and international standards. The humid tropical climate created special requirements for technical solutions.
