Abstract
Normally, the passengers on urban rail systems remain fairly stationary,
allowing for a relatively straightforward approach to controlling the dynamics
of the system, based on the total rest mass of the train and passengers. However
when a mischievous rugby club board an empty train and then run and jump-stop during the braking process, they can disrupt the automatic mechanisms for aligning train and platform doors. This is the rugby club problem for automated urban train control. A simple scenario of this kind is modelled in Hybrid Event-B, and sufficient conditions are derived for the prevention of the overshoot caused by the jump-stop. The challenges of making the model more realistic are discussed, and a strategy for dealing with the rugby club problem, when it cannot be prevented, is proposed.
