Decomposing efficiency into its managerial and its regulatory components: the case of European railways
Article Abstract:
Productive efficiency is decomposed into its management component and its regulatory component. Managerial inefficiency is the responsibility of management while regulatory inefficiency is attributed to the administrative, legal and institutional environment in which firms operate. This decomposition is applied to European railways whose quality of management and environment vary across countries. Findings indicate that technical efficiency is influenced by government intervention and can be enhanced by increasing the firm's autonomy.

Optimal lines for railway systems
Article Abstract:
A mixed integer linear programming formulation is developed for a line optimization problem aimed at the construction of optimal lines for railway systems. The optimal choice of traffic lines on a railway system should have sufficient capacity to be able to serve the known amount of traffic on the system. Appropriate relaxations and strong cutting planes with the commercial linear programming solver CPLEX 3.0 led to a solution of the real-world data.

Minimizing waiting times in integrated fixed interval timetables by upgrading railway tracks
Article Abstract:
A study on the cost benefit between the examination for reforming track states and the quality of the resulting timetable measured by the remaining waiting times is presented. Sub-optimal solutions by a hybrid genetic algorithm, including fuzzy logic, was developed. It was established that the integrated fixed interval timetable of a railway network does not guarantee non waiting times for passengers who are changing trains.
