Västlänken in Gothenburg is being planned because of the poor capacity. The trainstations capacity is today at its maximum due to its construction, resembling a bag.

In Stockholm there is much demand for increased train frequency. The bridge over Riddarholmen consists of two tracks and many trains pass this, causing a bottle-neck. The Citybanan will solve this with a new train tunnel beneath the Riddarholmen. After the completion, more potential for expansion of the railway network is possible. To achieve economic analyses of feasible railway constructions, several tools and computing programs has been utilized. By comparing the suggested solutions with a Zero-alternative in every case, results will show if the project is economically feasible. Despite the advanced programs available, these can never give more than a hint of how a project will turn out in the reality.

The population has grown and therefore the demand on railway transports has become more defined, especially in larger cities. The infrastructure has not developed in the same pace, obstructing both today's and future railway transports. This is particularly obvious in Göteborg, Stockholm and Malmö. Västlänken in Gothenburg is being planned because of the poor capacity. The trainstations capacity is today at its maximum due to its construction, resembling a bag. This results in incoming trains must take the same way out. To get around this problem plans are developed to build an underground tunnel that will connect the station. Presently, several options are being investigated. The train station in Malmö is also of the bag-type construction. To remedy this the Citytunneln is being planned, to solve the problem with an underground tunnel.
