Six months of passenger services in London
The Elizabeth Line, which began operation in spring 2022, is now marking six months of passenger service for London. The line has given the capital's transportation and commuting a much-needed breath of fresh air.
With this major milestone comes another. The number of trains-per-hour in central London have doubled to provide customers with even greater connectivity.
On November 6, additional services on the Elizabeth line were launched, running from Reading and Heathrow to Abbey Wood and Shenfield before reaching Paddington.

Delivering in Britain, for Britain
Siemens Mobility’s digital signalling and station management systems make journeys smooth and seamless, from station to station. The Elizabeth line is transforming the everyday journeys of passengers across London and the South East, and the communities the line serves, with Siemens Mobility technology at its heart.
The company utilised the skills and people at its sites in Ashby-de-la-Zouch, Leicestershire and Chippenham, Wiltshire as well as across the UK and leveraged the expertise within the global Siemens Mobility business, to deliver digital technology that revolutionises the way rail lines in London are run.
The CBTC signalling and control system for the central section of the Elizabeth line was designed, manufactured, installed, tested and commissioned by Siemens Mobility. The CBTC system enables high-frequency and automated train operation in the central section.
The Siemens Mobility systems link seamlessly with the main line railway signalling systems to the east and west of the central section - there are three different signalling systems that Elizabeth line trains need to run on! The CBTC system, Trainguard MT, was extensively tested in Braunschweig, Germany.
It was then integrated with other elements of the signalling and the platform screen door systems at Siemens Mobility’s manufacturing and testing facility in Chippenham, Wiltshire. Using digital technology to simulate other elements of the railway, over many months of extensive testing against multiple scenarios ensured that everything would run smoothly on the live railway.
Station and railway systems
The communication and control systems delivered by Siemens Mobility provide a host of digitilased systems that improve all parts of the line. The technology was developed at the company’s Ashby Customer Information Systems technology centre, and is run from the Elizabeth line’s Romford control centre or stations operations rooms along the route.
Testing was crucial for the highly complex huge station and central management systems. Over 30,000 connections from CCTV, public address, passenger rail and station information - many of which speak various computer languages. Real-life scenarios were virtually tested at Ashby as well.
The result of this ground-breaking digitalised integration is safe, reliable travel, with easily accessible, up-to-date information for passengers throughout their journey. For staff the ability to identify and respond quickly, will avoid incidents such as over-crowding, allowing for greater efficency in
Rob Morris, Managing Director for Rail Infrastructure UKI says:
"Hundreds of our people at Siemens Mobility’s Chippenham and Ashby engineering and manufacturing facilities, as well as colleagues in Germany and global R&D centres, have been crucial to bringing the Elizabeth line into service.
“Working to integrate so many different systems from different suppliers has needed a truly collaborative approach."
