Abstract
In present railway systems, the restoration of delayed schedules due to accidents or breakdowns, etc, relies solely on human efforts. Automatic restoration by a computer seems necessary in the near future, although at present it is believed to be impossible because of the complexity and the request of real time and absolutely accurate operations. This paper gives simulations of railway traffic by using cellular automaton (CA). The temporal signal breakdown is introduced to trigger off the delay whose time evolution is studied. We propose a set of rules which restores the delayed schedule to its normal state.
