ail organisations are working hard around the world, to improve train performance by tackling three fundamental problems: providing greater capacity, improving service reliability and reducing signalling system renewal costs.
more modern digital systems. These typically include systems based on the Europe-wide standard for train control and command systems – the European Rail Traffic Management System (ERTMS), which comprises of:

many replacement and upgrade programmes have been announced and planned to be operationally implemented over the next decade. For example, in the UK, over half of Britain’s analogue signalling systems with lineside ‘traffic lights’ controlling trains, need to be replaced within the next 10 to 15 years. Although a digital rail programme brings many advantages including those listed in the opening paragraph, it can also bring its own challenges. This article looks at two of these challenges, using case studies.
