Following the introduction of new trains with improved braking and acceleration performance operating on the GB mainline, there has been an apparent increased rate of Train Protection and Warning System (TPWS) Overspeed Sensor System (OSS) trips. There is a belief that this is because drivers are now driving to the increased performance of the new rolling stock and starting to brake later, at a point that would still allow them to comply with company professional driving policies and to stop at the signal or comply with the reduction in speed. However, this has the result that the train passes the OSS at a higher speed than the OSS is set for and the trainborne TPWS reacts and applies the emergency brake on the train.
This research will establish whether and what alternative trainborne TPWS OSS trigger delay timer settings could be applied to trains with better performance, without compromising the overall effectiveness and availability of the whole system or the safety of the railway.
