<p>We analyze access pricing for cross-border rail transport by two infrastructure managers. We compare access charges, consumer surplus and the profit of infrastructure managers under three régimes: one where infrastructure managers are unregulated, one where they are regulated, one where one is unregulated and the other one regulated. We note that, due to double marginalization, access charges are too high, and consumer surplus and the profit of infrastructure managers can be increased by inducing cooperation. We show that the first-best can be achieved by a delegated pricing scheme, where train operators pay access charges only to the infrastructure manager of the country of origin, with a transfer to the country of destination at marginal cost.</p>
