This study investigates the uses of public-private partnerships (P3’s) to finance infrastructure improvements for passenger trains running at “high speed.” It answers the following questions: is P3 financing best suited to construction of very high speed (vhs) rail projects or can it also be applied to projects that achieve “higher,” but not “very high” speed? If best suited to vhs development, why? If more broadly applicable, what precedents exist for applying P3 finance to less than vhs rail projects and in what specific circumstances? By answering these questions, the study aims to enhance the utilization of P3 financing for rail improvement projects, especially in Region 2.
