This data article offers two reference simulation models for the evaluation of performance and delays of a suburban railway line. Further, a sample output dataset is provided for validation of the model, and the sample output dataset could be used independently if the reader desires. The simulation is programmed in the OpenTrack railway simulation software Nash et al., 2004 (). The models are provided as a reference and tool for other researchers to validate and extend their studies in railway operations. These models were originally created for the research article "A Closed Form Railway Line Delay Propagation Model" Harrod et al., 2019 . That article proposes an analytical estimation of railway delay, and these models were used to validate the findings.
