Soon after tram operations were started, many problems arose. The hilly terrain of Kyiv presented the largest problem. On Bohdan Khmelnytsky Street, a pair of horses was not enough to pull the trams uphill. Therefore, another two pairs of horses were added, which did not improve the situation. Thus, mechanizing the tram using a steam-powered engine was attempted as a solution to the problem. However, the steam engines produced a lot of noise, which scared the horses and people, and produced a lot of air pollution.
