The paper deals with the problems of fulfilment of the new TEN-T infrastructure guidelines in Slovenia on one hand and the financing of upgrading and construction works for the new infrastructure on the other hand. The specific of our network is that the majority of our freight traffic is in transit that means this freight has no origin or destination in Slovenia and serves mainly to the foreign economy. The fact that the origin and/or destination of most of the freight traveling on our tracks are not in Slovenia is not the problem for itself, the real problem is that the railway undertakers are not fully charged for the costs they produced to the infrastructure as well as to the environment. This is the main reason why no major railway project in Slovenia is financially proved although the traffic volume forecast are enormous. With other words the Cost Benefits Analyses can not be positive enough because the costs are Slovenian and benefits are from the countries which transported goods through our country. New railway infrastructure can even not be proved by calculating of benefits by lowering of environmental costs with shifting the freight from the road to the rail. This is why because these environmental costs produced by the road traffic are actually also not ours, they are
forced to use since also the road freight transport is on our roads mainly in transit. The solution for countries like Slovenia lies in infrastructure fees which will cover full infrastructure and environmental costs or the totally different scheme of co-financing on the European level.
