- Competitive tendering was first introduced in 1989 on some regional lines, but since then this practice has become more and more widespread, and now encompasses the majority of both regional and interregional lines.
- Besides, these efficiency gains are greater when the two new companies specialize their production, either on passenger or on freight traffic.
We consider railways as a system which uses its infrastructure (length of lines worked, numbers of cars and wagons, staff strength) and a scale of market (number of inhabitants and tourists) for transporting passengers and freights. We estimate efficiencies of freight and passenger transportation separately on the base of different models. We use the database provided by International Union of Railways, which includes annual statistical data about biggest European railways companies from 1997 to 2006 to estimate model parameters.
A cost function is subadditive when a single firm can produce all relevant output vectors cheaper than two or more firms. In order to do so the test developed by Evans and Heckman (1984) will be used.

It was applied for the American phone company Bell System to assess the convenience of separating the management of local and long-distance services. The results indicate that at least for the companies of a greater size, an efficiency increase (as measured by lower costs), would be obtained from the separation of the current companies in two different companies of a lower size. Besides, these efficiency gains are greater when the two new companies specialize their production, either on passenger or on freight traffic.
