TfL - Baker Street Platform-to-train-interface

Disciplines: track, signals, civils, premises, electrical/power, operations and maintenance

SRC Infrastructure have recently written a feasibility study on a historic issue - Platform to Train Interface (PTI) at Baker Street Station, meaning customers have to navigate large gaps between the train and the platform edge. Platform two of the Baker Street Metropolitan line has one of the highest ‘fall down the gap’ incident rates across the entire underground network. This has been a problem for over ten years!

SRC’s study on this project was multi-discipline, requiring input from several engineering disciplines: track, signals, civils, premises, electrical/power, operations and maintenance. Each of these disciplines were seamlessly integrated throughout the project to propose options to rectify large PTI gaps. SRC took a holistic view of the issue and explored various options that provided flexibility to the client and an incremental benefit to TfL when compared to cost.

SRC provided TfL with options to take through the pathway gate stages that will reduce some, if not all, PTI gaps– significantly reducing the number of ‘fall down the gap’ incidents and improving the overall safety on platform two of Baker Street Station. SRC and TfL worked collaboratively throughout the project, and through the process, a new approach to optioneering and feasibility studies was developed that has now been deployed across all APCD projects.

Overall, the project considered all the historic PTI problems faced at the platform and ensured an integration solution was developed to tackle the issues and improve the safety of the platform.
