As state transportation planners seek to build or support sustainable transportation systems in an era of economic challenges, they find few publicly available rail analysis models for stakeholders to examine the environmental impacts, socio-economic effects and costs associated in investing in rail infrastructure. This paper, taken from a University Transportation Center Program (UTCP Region 6) funded study presents stakeholders with the building blocks necessary to develop an integrated rail analysis model. It also reviews the current state of rail modeling, current rail models and presents a preliminary intermodal rail costing model .
