This article discusses the following issues: justification of the feasibility of intra-city railway communication on the example of St. Petersburg, creation of a basic algorithm for commissioning this project for this purpose, the analysis of existing methods used for the introduction of new types of transport was carried out, the main advantages and disadvantages of railway communication are given, the basic algorithm for the introduction of intra-city railway communication is given, the possibility of implementing the project in St. Petersburg is considered. The commissioning of the intra-city railway network allows: to reconsider the issue of the development of the transport network of the agglomeration, promotes the development of an off-street mode of transport that can compete with the metro, redistribute passenger flows coming from the Leningrad region and the suburbs of St. Petersburg, improve the environmental situation in the region by reducing congestion at the entrance to the city by transferring to the intra-city railway communication, which will also reduce the travel time of all traffic participants.
