Railway investments are substantial financial commitments.In
most countries,developing and maintaining the railroad network
is a public responsibility.As with all public transport policy
decisions, benefits can be weighed against costs and the cost-
efficiency of different investments can then be compared.This
makes well-developed and well-structured cost-benefit analysis
(CBA) methods indispensable.The increasing interest for investments in high-speed railways makes this even more important,considering the huge costs at stake.
