Abstract

Britain's railway industry is implementing the vision of the system in the next thirty years, as outlined in the Rail Technical Strategy (2012); the main objectives to achieve are: carbon and cost reduction, capacity increase and customer satisfaction.
The timetable design process is identified as a key enabler of the strategy's implementation.The current method in use is considered as a lengthy process with little computer support and optimisation.
This study tries to overcome the outlined weaknesses of the existing method by proposing a more automated process in which the optimisation of a timetable is a properly design stage.
The method has been applied to minimise the total energy consumption of five trains on the Aberdeen-Inverness line, while meeting operational and safety constraints. The results showed a reduction in the total energy consumption of 7%, while the average train total journey time is increased by 1% in comparison with the initial schedule.
