Congestion, allocation and competition on the railway tracks
Congestion, allocation and competition on the railway tracks
Although railways are traditionally a closed system, with centralised control, they can still experience congestion in the form of delays due to perturbations in demand and supply. Such congestion increases exponentially with capacity utilisation. Traditionally, on-track competition between railway companies has been limited and capacity has been allocated using administrative procedures. More recently, as railways have been opened up to competition, market-based allocation mechanisms have been developed, often overseen by an independent regulator. These include track access charges based on short run marginal cost, long run incremental costs and various forms of fully allocated costs. These access mechanisms are reviewed in light of increasing competition in railways, both on- and off-track, and their prospects are assessed in the light of emergent digital technologies.

Abstract
Although railways are traditionally a closed system, with centralised control, they can still experience congestion in the form of delays due to perturbations in demand and supply. Such congestion increases exponentially with capacity utilisation. Traditionally, on-track competition between railway companies has been limited and capacity has been allocated using administrative procedures. More recently, as railways have been opened up to competition, market-based allocation mechanisms have been developed, often overseen by an independent regulator. These include track access charges based on short run marginal cost, long run incremental costs and various forms of fully allocated costs. These access mechanisms are reviewed in light of increasing competition in railways, both on- and off-track, and their prospects are assessed in the light of emergent digital technologies.
