In the 1990s, Lengiprotrans designed the St. Petersburg-Moskovsky Motor Wagon Depot at the Metallostroy station for maintenance and repair of electric trains.

In 2007–2009, the institute designed the reconstruction of the depot for servicing high-speed Sapsan trains intended for operation on the high-speed section of the St. Petersburg - Moscow - Nizhny Novgorod railway. The Sapsan trains that were being commissioned required a modern repair infrastructure, which could be provided through the reconstruction of the Metallostroy depot.

The design and survey work was complicated by the presence of a high level of groundwater. In this regard, the design of deep drainage was carried out on the territory in the places of expansion of the production building of the depot, as well as in the places of installation of inspection holes at low elevations relative to the floor level.

According to the project, the reconstruction of the existing workshop, designed earlier for servicing the high-speed trains "Sokol", was developed. In the reconstructed workshop, three inspection ditches of an overpass type and suspended multi-level platforms were provided, which allows simultaneous maintenance of various working areas of the electric train.

The scope of work included the reconstruction of the wheelset turning shop without rolling out from under the train and the diagnostic shop. The latter provides equipment for complex diagnostics of wheelsets according to several tens of parameters. In this case, diagnostics are performed on the fly, when the train passes through the shop. The initial data is transmitted to the computer network of the Oktyabrskaya Railway, where the wheelset turning program is automatically set.

The depot was equipped with modern equipment from European companies such as Siemens, Hegenscheidt. The German organization "ProKonzept" was involved in the development of technological solutions. At the same time, Lengiprotrans' technologists adapted the documentation of the German company to the standards of the Russian Federation (fire, sanitary, etc.), developed and coordinated the project documentation in the examination.

Modern technological equipment of the Metallostroy depot makes it possible to implement almost all types of maintenance and repair of high-speed trains. Thanks to this, it became possible to travel from St. Petersburg to Moscow in four hours.
