Perhaps the biggest surprise at the Trako 2017 fair, held in Gdańsk in September, was the presentation of a modified M62 converted into… an electric locomotive. Frankly speaking, not much was left from the old ‘Gagarin’ – just frame and trucks, the latter thoroughly modified. The conversion began in 2014 at the Rail Polska works ZTK in Włosienica, basic design being developed by VIS System company of Gliwice. For this purpose, one section of the 2M62-1006, purchased from Estonian railways EVR in February 2005, was used. The body is completely new and the cab offers much higher comfort for crew, including air conditioning, refrigerator and tea-pot. Maximum speed is 100 km/h and the locomotive, designated 207E, is intended solely for freight traffic.

First tests began in January 2018 at the Railway Institute test track center in Węglewo, Lower Silesia. Later they were continued under the supervision of the Rail Vehicles Institute of Poznań. At the time of writing (February 2019), 207E-001 still has not been certified for commercial operation and tests are still under way. According to Rail Polska, second example is under construction. It is planned to convert thirty M62s, including twenty for own use and ten for sale or lease. A ‘last mile’ version is also planned, with auxiliary power provided by a battery rather than a diesel generator. ZTK has already purchased about twenty ‘Gagarins’ for future conversions.
