Disruptions often result with partial capacity reduction without resulting with a complete breakdown. This study aims to move beyond the analysis of complete failure by investigating the impacts of partial capacity reduction on public transport network performance. We analyse the relation between the extent of capacity reduction at the line level and its consequences on societal costs by performing a full network scan. This analysis framework is applied to planned temporary disruptions in the rapid public transport network in Stockholm, Sweden. Our results indicate that the network is highly vulnerable since it is characterized by greater negative impacts in a disproportional relation to the increase in the original capacity reduction. The non-linear properties of network effects and route choice result in non-trivial relation which carry implications on disruption management the deployment of mitigation measures.
