Traditional line-side signalling is expensive through installation, operation and maintenance. It is inflexible; signalling headways and hence capacity are determined by physical location of signals, track circuits and associated infrastructure, and it is vulnerable; signalling cables and apparatus are frequently stolen by metal thieves – it’s scrap value being very high.
