Why Wimbledon

The hardest commuter operation in Europe.

Wimbledon “A” is historically famous for managing some of the most intense commuter traffic in Europe using unique semi-automatic signal mechanics and manual crossover work. By modelling this specific environment we prove the platform can decode complex mixed manual/automatic interventions, trace sub-threshold dwell variances, and establish a repeatable methodology for the rest of the network.
