The Holy Trinity Church at the railway station "Omsk" was built with funds from the Alexander III Foundation and the Committee for the Construction of the Siberian Railway. Funding also came from the Baev family, honorary citizen A. Derov, and anonymous benefactors. The church was solemnly consecrated on November 24, 1900.

In 1903, the interior of the church was painted with oil paint, and the ceiling was decorated with paintings. The wooden floor was replaced with a floor made of colored stone tiles. The church building was made of stone, with a bell tower built in a unified style. The fence around the church was wooden, and there was no cemetery associated with it. The parish's metric books have been maintained since 1897.

The history of the construction of the Trinity Church at the Omsk station is noteworthy as it is linked to two significant events of the late 19th and early 20th centuries: the construction of the Great Siberian Railway and the activities of the Alexander III charitable foundation. The church and the school associated with it were designed and built by the chief of the track service section, engineer Alexander Petrovich Hegstrom. The laying of the foundation took place on August 3, 1897. The church under construction received high praise and was considered the best along the entire line. The consecration was conducted by the Bishop of Omsk and Semipalatinsk on November 24, 1900.

The church, designed for 750 people, was built of red brick in the style of Russian architecture of the 16th and 17th centuries. The massive two-tiered volume (octagon on a square) was topped with three rows of keel-shaped kokoshniks and a round drum with an onion dome under an eight-pointed cross. The bell tower was adjacent to the church, its height emphasized by its multi-tiered structure, kokoshniks, and narrow windows on the tent.

Presumably, in 1930, the church was closed. The library of the Trinity Cathedral was confiscated on July 6, 1930, during its liquidation by the acting head of the administrative department, Ignatov. The books were accepted without an inventory. A document was found, likely from the same year, undated, regarding items transferred by the City Finance Department from the Trinity Railway Church to the city of Leninsk for the West Siberian Regional Museum, signed by the museum director S. Kochnev.

The church was demolished, and a monument to V.I. Lenin now stands in its place (sculptors Yu.G. Neroda, Yu.M. Rukovishnikov, architect B.V. Arkhipov) with a park surrounding it.

The reconstruction project for the railway station square, developed by the "OmskGrazhdanProekt" institute, includes the restoration of the Trinity Church. A serious reconstruction has begun at the Railway Station Square: the building constructed during the Soviet years opposite the station on the site of the church has been demolished.
