Cars are loaded on the railway wagon for the railway shuttle at Jorvas station or Tabasalu (planned) station. At specific time the shuttle start for the other end and the car is offloaded, and the journey can continue. The plan is to achieve almost the same service level a road tunnel under the Gulf of Finland would provide.
Jorvas at the intersection of road 50 and 51 is at perfect spot for road connections toward Estonia. Both roads are in good condition but at rush hours the traffic is rather heavy but usually without traffic jams. It is rather hard to find a place in the southern Finland with better "working" car connections.
In Estonia the situation is different, here we plan a new station at Rannamõisa road, road 390. The Rannamõisa road is a rather "small road" and maybe too small for this traffic from what we call Tabasalu station. By driving south east from Tabasalu station you can reach Tallinn.
An important aspect is that the railway connection under the Gulf of Finland extends Via Baltica to southern Finland and Helsinki area. Via Baltica, officially known as European route E 67, goes from the Estonian capital Tallinn, but for our purpose the endpoint is possibly the Finnish capital Helsinki, to the Polish capital Warsaw. It is the most important highway between the Baltic States, and fairly important for traffic from Finland, but also this may change with the railway connection Tabasalu-Jorvas, to Central Europe as well as the other way around, or maybe we should replace then " Central Europe " with " eastern part of Central Europe ".
Maybe Via Baltica should be extended to the north by merging E 67 and E 75 to Vardø in Norway ? This merge will really create something that is a real "Via Baltica". A route to see reindeers (poro) and Santa (Jõuluvana)?
