New signalling technology for Circle and Hammersmith & City Lines 2018

Thales has tested a new signalling control system on sub-surface trains on the Circle and Hammersmith & City lines, which enable trains to run closer together. The test aims to provide a more frequent service, reduce waiting times and help boost capacity for the Circle, District, Hammersmith & City and Metropolitan lines. The system will go live on the first section of the network as early as 2018.

596 Thales has tested a new signalling control system on sub-surface trains on the Circle and Hammersmith & City lines, which enable trains to run closer together. The test aims to provide a more frequent service, reduce waiting times and help boost capacity for the Circle, District, Hammersmith & City and Metropolitan lines. The system will go live on the first section of the network as early as 2018.

Further testing weekends will commence in the coming months as the system is being progressively installed across more of the network with a capacity increase of up to 33% across all four lines, which makes up 40% of the underground. It will also mean that Night Tube services can be introduced on these lines in the future.

The system is designed with the intention of reducing the number of signalling problems and improve the accuracy of real-time customer information. Services will begin to increase in frequency from 2021 when more of the network is operating the new system, and all four lines will be using the system by 2023.

Testing took place between Hammersmith and Latimer Road and featured three newly-enabled S Stock Trains. It involved using a signalling system to manage the distance between trains. The new S Stock trains are currently having new equipment installed, with 30 already fitted by 513 Bombardier.

The next testing weekend will start in December, with installation work continuing throughout the year.

    Countering truckers’ parking conundrum
    Colin Sowman hears about a new truck parking information system being piloted across eight states. Legislation limits truck drivers’ hours with the result that they are often caught in a situation where they need to stop either for a break or an overnight rest. But as truck parking is in short supply, truck drivers spend an average of 56 minutes a day searching for available spaces and are often faced with the choice of driving beyond their permitted hours or parking illegally.

    Fusion Processing’s Jim Hutchinson looks at a two-year trial of the company’s cyclist detection system. Is cycling in a city dangerous? Well, that depends where you are and how you view statistics. Malmö is far more bike-friendly than Mumbai and the risk can either be perceived as small - one death per 29 million miles cycled in the UK in 2013 - or large - that equated to 109 deaths in the same year. Whatever your personal take on the data, the effect of these accidents can be felt indirectly too. News of c

    Vehicle identification systems aid dynamic bus operations
    David Crawford looks at a global trend towards more efficiency in less space As buses gain increased profile in the public transport mix needed for modal shift, attention is turning towards improving terminal layouts for more efficient handling of services and passengers. Locations, too, tend to be in central areas of cities, where sites are restricted and land values high. Enter the dynamic bus station, which uses modern vehicle identification systems to optimise space use and streamline service operation
