We present a multi-agent system for studying the allocation of discrete, congested resources among heterogeneous strategic agents, motivated by the problem of railway slot allocation under deregulation. Multiple operator-agents, differing in size and capacity, interact through a shared auction mechanism over repeated rounds under timeconstrained decision-making. The mechanism combines a congestionbased base price that increases with aggregate demand with an asymmetric corrective adjustment that penalises the agent requesting the most slots and rewards the agent requesting the fewest, and is designed to mitigate strategic dominance by large agents while preserving transparency and congestion sensitivity. We formulate the interaction as a repeated game with incomplete information and implement the system as a realtime, web-based multi-agent environment in which human participants control individual agents and observe live marginal-cost and competitor feedback.  \nWe report exploratory observations from two structured sessions with domain experts acting as operator-agents. The congestion mechanism responds to aggregate demand as designed and the corrective incentives are actively triggered, but agents representing large operators persist with high-request strategies despite the penalty, suggesting that corrective pricing is necessary but not sufficient to neutralise strategic dominance in this multi-agent setting. A post-session debrief indicates that participants’ decisions were driven by the assumed agent role rather than personal disposition, and provides qualitative support for strategic motives, such as preserving market presence and raising rivals’ costs, operating alongside short-term profit maximisation. We discuss implications for multi-agent mechanism design under asymmetric budgets and outline directions for analytical validation and larger-scale multi-agent experiments.  \nKeywords: railway capacity allocation · auction model · market design · deregulation · Trafikverket · transport economics.  \n2 B. Roungas et al.  \n1 Introduction  \nThe allocation of scarce, congested resources among multiple strategic agents with heterogeneous capabilities and objectives is a recurring challenge in the design of multi-agent systems. Railway capacity allocation under deregulation provides a particularly clear instance of this problem. Over the past decades, railway systems in many Western countries have opened train operations to competition while retaining the underlying infrastructure in public ownership. This institutional separation creates a multi-agent setting in which train operators (who are agents that differ substantially in size, financial capacity and service portfolios) compete for discrete slots on a shared infrastructure managed by a public authority. Unlike private-market resource allocation, the authority is required to balance economic efficiency, competition and societal welfare rather than pursue profit maximisation alone [1], which places distinctive constraints on the mechanisms that can govern the interaction.  \nOne of the most persistent challenges arising from deregulation is the management of conflicting capacity requests from multiple operators, particularly in high-demand corridors and during peak periods. Train paths, or slots, constitute discrete and scarce resources, and their allocation has significant implications for market structure, service quality, and long-term competition [13] . Traditional administrative allocation mechanisms often lack transparency and may fail to provide appropriate incentives for
