- Abstract
- Only well-maintained railway systems can function without severe interruptions. However, maintenance activities can themselves cause train delays if they conflict with train movements. Trackwork refers to maintenance performed on a railway track. This study aims to investigate the effect of trackwork on train delays in Sweden. It presents a logistic regression analysis based on more than 225,000 planned trackwork and 25,600,000 train movements during 2017. The results show that trains that pass through trackwork on single-track segments were on average 44% more likely to be delayed than those that do not. The corresponding value for double-track segments was 25%, and the weighted average was an increased risk of 31%. With the number of... (More)
