This is a series of portraits of people who work as traffic controllers and safety officers at railroad crossings.
In Ukraine, the railroad traffic controller profession still exists and about 80% of workers are women. They spend long shifts in small dedicated buildings beside the tracks.
Ukrainian photographer Sasha Maslov shot portraits of female workers of the Ukrainian railway company from all over the country, which are compiled in a photo book by Osnovy Publishing.
Much of Maslov's work has concentrated on exploring his native Ukraine.
Ukrainian Railroad Ladies book won the Lens Culture Exposure Awards in Jury Selection and Sony World Photo.
Since then, some have been covered with protective wiring.
