S Stock introduction - integration on a Victorian railway

S Stock is now replacing 50 year old trains on the Metropolitan line, with a commensurate step change in technology, functionality and performance. It is being introduced onto a railway that has its origins in Victorian times and includes the oldest section of underground railway in the world. This has presented a series of integration challenges that have had to be met.
The presentation will firstly cover the S Stock train itself, focusing on the features that are novel to London Underground and on the degree of system integration within the train necessary to meet passenger and operator expectations. The infrastructure changes required to support the new trains will then be described together with an overview of the system testing and validation work carried out.

Geoff Bolton is the S Stock Project Engineer for LU, having been with the company for 26 years. He has previously worked on new Rolling Stock projects for the Central and Northern line upgrades, focusing on traction and auxiliary systems, as well as a number of smaller projects.

He has spent the last 7 years working on S Stock from pre-concept through to service introduction and reliability growth phases. He is a Chartered Engineer and MIET, and is currently on the organising committee for the IET’s Electric Traction Systems Course.
