By the end of the 1880s Vladivostok had about 600 wooden and more than 50 stone houses, some two or three stories. Most buildings were grouped in the area of today's central square and the Matrosskaya Sloboda (Sailors' Suburb), from the Obyasneniya River to the Gaydamak tram stop. In 1891, construction of the Trans-Siberian Railway began in Vladivostok. During the 1890s, shipping to Kobe, Nagasaki, and Shanghai began. In 1897 a new commercial port was opened in Vladivostok, and regular rail service to Khabarovsk began.
