The Scent of Creosote in Kharkiv's Metro: A Story of Wooden Sleepers.

The Source of the Scent in Kharkiv's Metro

According to Novyny.live: The distinctive smell noticed by passengers in the Kharkiv Metro is caused by creosote, a chemical compound used to treat the wooden sleepers that support the tracks. Chief Engineer of the Kharkiv Metro, Igor Demyanenko, confirmed this is the system's characteristic odor. Creosote is an oily, petroleum-based substance applied to prolong the lifespan of these timber components. This practice is common in many railway systems to prevent rot and decay.

The scent of creosote is more pronounced at newer stations where recently treated materials have been installed. Throughout history, subway systems in different cities have had their own unique smells. For instance, the London Underground in the 19th century carried the scent of smoke from steam locomotives, illustrating the evolution of technologies and materials used in underground transit networks.

Kharkiv Metro's Unique Features

The Kharkiv Metro also holds a unique distinction: it contains the world's only enclosed metro bridge, constructed in the 1980s. According to Dmytro Komarov, the metro's scent has varied throughout its history, reflecting changes in technologies and construction materials. Thus, the smell of creosote in Kharkiv's metro is part of its operational history and identity.

The presence of this smell not only highlights the specific materials used but also reflects broader technological shifts in public transport. Given the metro's unique architecture, it's important to recognize that its scent is part of the city's cultural heritage and a testament to historical transformations in transit systems. This may also prompt further discussion and research into the safety of using such chemical compounds in public infrastructure.
