Low cost signalling systems

Efforts over the years to reduce signalling costs are reviewed considering reductions in facilities and savings in manpower, common on British Rail in the fifties and sixties, to various more recent attempts to replace traditional signalling systems with low cost equivalents. Some recently resignalled lines and proposals in the UK and overseas as well as some of the systems that have been in use for many years are considered. The ongoing costs and limitations of the systems are outlined, together with some suggested improvements to increase the reliability and performance of existing installations, using recent advances in technology. Further examination will reflect on the differing requirements of operators and infrastructure owners. In particular the need is to reduce ongoing costs without reducing flexibility, and the requirement to keep investment expenditure within strictly defined limits. This section concludes by looking at possible future developments in this field.
