South – North Stream Railway Line (SNS)

What is the new South North Stream Railway line (SNS)?

This is a high velocity railway line with a huge capacity to carry out transportation tasks between the new ultra large port of Maroneia on the Aegean Sea and port Wisla at the Baltic Sea. The railway track is located in six project countries, all of which are part of the European Union. These are Greece, Bulgaria, Romania, Hungary, Slovakia and Poland. 

What are the advantages of new South North Stream Railway Line (SNS)?

The SNS is a unity of railway infrastructure, rolling stock, logistics centers  and common management.

The SNS relies on a standard European track gauge double track railway line, whereas in some specific sections we will use three tracks. The railway line is designed for both freight (200 km/h) and high-speed passenger trains (400 km/h).

Freight transportation will be the main business of the new South North Stream Railway Line (SNS)

By applying advanced technologies in the SNS, short travel and delivery time of the goods will be achieved. Therefore, higher utilisation of the infrastructure and the rolling stock will lead to competitive conditions for all end users.

Digitalisation n, n> 2

  • Long freight trains up to 1800 m
  •  High-speed freight trains
  •   Highest level of ETCS and ERTMS
  •   Movement of trains without drivers
  •   Automated  coupling
  •   Automated shunting
  •   New type of wagon for 200 km / h commercial speed
  •   Energy recovery and storage
  •   Freight EMU
  •   Low noise
  •   Remote control
  •   TEN-T § TEN-E

The SNS railway line has fifteen times bigger throughput than an average European line railway. Therefore, an enormous amount of cargos can be transported along the line - up to 1.2 billion tons per year.

Safety will be of paramount importance.

For freight transport  the SNS is characterized by:

      high capacity              +           high commercial speed                 =                 high efficiency 

            in a block train:                         up to 185 km/h                                                      competitive prices 

          275 TEUs or 720 new cars      average speed for the freight trains              prompt deliveries 

Since common general rules for the entire SNS  railway line will apply for infrastructure, rolling stock, operators, the access to infrastructure, the customs and tariffs, as well as for cross border procedures (One Single window – One Stop Shop), this single and centralised traffic management will have many positive advantages that will make the railway line preferred and more economically viable.

For instance, trains will not stop at the border and will not stop either to change drivers. As a result, the freight trains will travel the distance of 1626.220 km from Port Maroneia on the Aegean Sea to Port Wisla  on the Baltic Sea for only  9 hours and 21 minutes. Alternatively, passengers traveling between Bucharest and Warsaw by the high-speed train will travel the distance for only 3 hours 35 minutes or between Sofia and Bucharest for 2 hours and 42 minutes.
