Public Procurement of Railway Infrastructure Maintenance : A Linear Regression Analysis

Swedish railway infrastructure maintenance has been outsourced through gradualexposure since 2002. The idea behind outsourcing was to reduce cost and improveefficiency. However, railway maintenance cost has increased faster than railwaymaintenance operations, resulting in neglected railway maintenance. Since railwayoperation is governed by the contract design the purpose of this paper was to explore therelationship between contract design and maintenance outcome within Swedish railwayinfrastructure maintenance. To explore this relationship linear regression analysis wasused. The result indicates that asset knowledge and accessibility to the track areimportant to consider for improving maintenance operations
