In 2010 the legal barriers for international, intramodal competition in long-haul passenger transport in the railway sector will be abolished. This report analyzes the extent to which effective competition will arise in long-haul passenger transport after liberalization-from 2010 onward-and how co-operative agreements between European rail operators may impact the liberalization process. The study also provides an overview of the existing literature related to entry and intramodal competition in the rail sector, as well as intermodal competition between aviation and rail. In addition, it provides a review of the legal and regulatory environment of the sector at a European level and evaluates current organizations operating in it. The following are the main conclusions:- We find robust evidence for effective competition between low cost airlines (LCAs) and rail operators. A rail operator loses at least 7% of its passengers and 8% of its passenger kilometers due to entry by LCAs. We also find evidence of negative price effects of strategic LCA entry in both first class and second class. This demonstrates that LCAs are a significant competitive constraint for rail operators.- Based on a revenue & cost model ('R&C model'), only a minority of long distance origins and destinations (O&Ds) are profitable with respect to both operating profitability and total profitability from a pre-entry perspective - that is before entry by competing rail operators. This result does not change drastically even under optimistic but reasonable assumptions regarding future changes in demand, costs, and degree of intermodal competition.- An analysis of various entry strategies identifies the most profitable strategy as entry by an independent entrant with inferior technology. However, such a strategy is specifically vulnerable to legal and strategic limitations on exploitation of network effects (e.g. by imposing national levies or incompatibilities in ticketing or train schedules).- Overall, we find very limited evidence for intramodal competition arising on international O&Ds for long distance passenger travel after 2010, while past experience from airline alliances - although in a different competitive setting - promises significant efficiency gains as a result of international alliances.
