document: A solvable queueing network model for railway networks and its validation and applications for the Netherlands The performance of new railway networks can not be measured or simulated , as no detailed train schedules are available . Railway infrastructure and capacities are to be determined long before the actual traffic is known . This paper therefore proposes a solvable queueing network model to compute performance measures of interest without requiring train schedules -LRB- timetables -RRB- . Closed form expressions for mean delays are obtained . New network designs , traffic scenarios , and capacity expansions can so be evaluated . A comparison with real delay data for the Netherlands supports the practical value of the model . A special Dutch cargo-line application is included
