Siemens, TfL Bakerloo Line: CBTC Upgrade for Enhanced Rail Capacity

“`html

Introduction

In July 2024, Siemens Mobility was awarded a contract by Transport for London (TfL) to upgrade the signalling system on the Bakerloo line, which includes work at the Edgware Road signalling cabin. The project, valued at approximately £80 million, is scheduled to be completed by 2029.

Project Scope and Objectives

The contract encompasses the design, supply, installation, testing, and commissioning of a new communications-based train control (CBTC) signalling system. This upgrade aims to enhance the reliability and capacity of the Bakerloo line. The new CBTC system will replace the existing, aging signalling infrastructure. The project’s scope also includes modifications to the existing trackside infrastructure and integration with the line’s rolling stock.

Contractual Details

Siemens Mobility will be responsible for the overall project delivery, including project management, system engineering, and software development. The company will also provide training to TfL staff to ensure the effective operation and maintenance of the new signalling system. The contract’s financial value is approximately £80 million. The project’s completion is targeted for 2029.

Technological Advancements

The new CBTC system will enable automatic train protection and automatic train operation. These features will improve safety and allow for more frequent train services. The implementation of the CBTC system will lead to significant improvements in operational efficiency. It will also facilitate better management of train movements along the Bakerloo line.

Impact on Operations and Infrastructure

The upgrade is essential to maintain and improve the performance of the Bakerloo line for the next several decades. The project will affect the infrastructure, requiring careful planning and execution to minimize disruption to passenger services. This includes upgrades at the Edgware Road signalling cabin.
