RSSB research to reduce costs of electrification
Featured story

Electrification of the railways is one of the greatest investments in infrastructure in the UK.

An RSSB research project 'Optimising the sub-sectioning arrangements on AC electrification' has created a model to reduce the costs of electrification, and maintain high capacity across the network.

The model considers the optimal distance between switches. The switches ensure that, if there is a power failure on part of the Network, the rest of the network is not affected.

Keeping failures in a single location enables trains to be rerouted along other routes, thereby maintaining capacity, reducing costs associated with delays and improving the customer experience.

The model, which can be fully integrated with Network Rail’s route model for electrification, uses what if analyses to determine the optimal design for new schemes. It can also be used retrospectively to improve existing schemes.
