Railways around the world are facing capacity constraints due to the considerable future demand. In North America, the traffic is projected to increase 88% by 2035. It is clear that network capacity must be increased , but the question is how to allocate capital in the best possible way. In this research, we demonstrate a decision support tool to determine how to optimize the allocation of capital investment for capacity expansion projects. Such a tool will help railroads maximize their return from capacity expansion and thus be better able to provide reliable service to their customers, and return on shareholder investment.
