Over the coming years Tube Lines' Jubilee and Northern Lines Upgrade Project (JNUP) will be replacing the fixed-block trip-cock protected signalling and control system currently used on these lines with a transmission based moving block train control system aimed at improving the operational safety and performance of the underground system. Passengers using the Jubilee Line are already benefiting from increased capacity provided by a 7th car recently added to the rolling stock. In conjunction with the new train control system a number of additional enhancements that are also to be delivered as a part of the JNUP are intended to further reduce the constraints of the existing system and increase the performance of the rolling stock, offering an improvement in the overall journey time capability made available to London Underground. As far as possible, these changes will be implemented "behind the scenes" from a passenger's perspective, with minimal disruption to normal service operation. This presentation will provide an outline of the way in which the systems and safety engineering are being undertaken on the JNUP, taking into account the scale of the challenges faced.
