Economic feasibility analysis conducted by Birmingham Centre of Railway Research and Education (BCRRE) has found the integration of the innovative Smart Bolt into rail networks offers potential to automate inspection and maintenance to enhance safety and operational efficiency within the railway infrastructure.

The study found that the use of Smart Bolt presents a valuable opportunity for advancing railway maintenance with real-time monitoring of fasteners in track switch point operating equipment. Testing confirmed the ability of the Smart Bolt to distinguish between functional and faulty bolts using duty cycle measurements and their potential to detect load increases via voltage changes.

Research Fellow at the University of Birmingham, Huayu Duan, says: “Condition monitoring has always been a significant area of R&D in railway infrastructure. This feasibility analysis has demonstrated the viability of the wireless Smart Bolt for the rail network and lays the groundwork for Phase 2 development of a full-scale prototype. We look forward to continuing to work with Anstee Indication Systems.”
