Ali Sadeghi, program manager for new major lines at the Swedish Transport Administration, tells Ekot that the new proposals take a slightly different approach.
– One of the alternatives has a much more national perspective and few stops and that you should go from Stockholm to Gothenburg and Malmö as quickly as possible.
The four new research alternatives therefore, they are designed a little differently and provide different benefits, Sadeghi says.
– Another extreme in the research alternatives is what more or less connects a system with much more regional anchorage.
The government has commissioned the Swedish Transport Administration to come up with proposals on how new trunk lines for high-speed trains can be built, and then at a maximum cost of SEK 205 billion.
This means that the system being planned today, which was previously negotiated in the so-called Swedish negotiations, has had to be significantly reduced.
– It requires important measures around the routing of lines and stations are there or not, says Sadeghi.
The question of that The construction of new trunk lines is politically hotly debated. It remains to be seen if any of the alternatives will eventually become a reality.
The new plans of the Swedish Transport Administration have received criticism from municipalities and regions because some train stations have been located outside city centers, which means a deterioration according to critics.
In the four alternatives, there are different proposals for this, says Ali Sadeghi.
– Each alternative has different compensations. In the research alternatives, there are central stations, but there are also examples of stations that are located outside of an urban area, he tells Ekot.
The Swedish Transport Administration is now raising also the actual cost evaluation for the previous proposal, which the regions and municipalities thus approved in preliminary agreements through negotiations in Sweden.
The cost of building in this way is estimated to increase by 50 billion SEK, from 245 billion SEK to 295 billion SEK.
– It is complex to expand a high-speed network and at the same time combine it with many stops. It affects capacity and generates a larger building mass such as bridges and tunnels, Ali Sadeghi, program director for new main lines at the Swedish Transport Administration, tells Ekot.
Recently presented the construction company Skanska’s study that it would be much faster to build a high-speed railway if it were run on bridges, which are built on piers, rather than built on the ground. The construction time would be about half, nine years.
The Swedish Transport Administration has analyzed this construction technology, and several others, in its new research. The authority does not believe that the pillar technology works for the whole railway, but for the parts.
– Regarding the pillar technology, we see that it could have some potential both in terms of the climate problem, the cost problem and the weather problem in certain parts of the route.
In research leads not the position of the Swedish Transport Administration on whether one alternative is better than the other or what technology should be used.
– We will not take a position on anything. We describe four alternatives and how it stands on its own and how they relate to each other. The same goes for technical solutions.
