Signals at Green

In both mainland Europe and the UK, a myriad of signaling systems are used to regulate trains. This article discusses how the deployment of the European rail traffic management system (ERTMS) could harmonize these signaling systems. Although the concept of the ERTMS goes back to the early 1990s, progress has been slow and concerns have been raised concerning the cost of fitting the equipment to rolling stock and the vague nature of early guidance documents. However, recent steps toward implementation have been made and the first UK field test of the system should be operational by 2008. One of the key features of ERTMS is the provision of an automatic train protection component that would ensure that trains operate within safe distances and speeds. Most of the present and future installations of the ERTMS will be on new railways and high-speed lines.
