GERT8030 Iss 3
Requirements for the Train Protection and Warning System (TPWS)
This document mandates the requirements for the Train Protection and Warning System (TPWS), the primary purpose of which is to minimise the consequence of a train passing a TPWS fitted signal at danger and a train overspeeding at certain other locations on Network Rail managed infrastructure. Additionally, it can be expected that TPWS will reduce the number of signals passed at danger (SPADs) at TPWS fitted signals. This document will be superseded by issue four on 1 December 2012.
