Primorskaya Railway

Primorskaya railway was located near Saint Petersburg and it lay on the route Saint Petersburg, Sestroretsk, Beloostrov. The railway was served by steam locomotives from the moment of opening and before joining to Oktyabrskaya railway in 1925.

Joint-stock company
Many articles refer to the "Joint-stock company of the Prinorskaya St.-Peterburg-Sestroretsk railway". It is not known whether the misspelling of Primorskaya actually appeared in the company's title. The title implies that the western terminus of the railway was intended to be Primorsk but it did not reach Primorsk within the lifetime of the company.

Construction
The line was constructed in three parts:
 * Ozerki line, opened 23 July 1893
 * Primorskaya Line
 * first stage opened 12 July 1894
 * second stage opened 31 October 1894
 * third stage opened 26 November 1894
 * Tovarnaya line, opened May 1904

The route of the line in the Saint Petersburg area is difficult to follow because various changes were made between 1894 and 1928. Of particular note was the closure of Primorsky Rail Terminal (due to flooding) in 1924 and the re-routing of trains to Finlyandsky Rail Terminal.

Technical stops
For technical needs and for travel of trains technical stops were necessary.
