Smart DC Stray Current Monitoring and Reduction in Railway System

I&T Wish Smart DC Stray Current Monitoring and Reduction in Railway System
(REF : W-0015)
Matched I&T Solution
Trial Project
Summary and Challenges

The objective of the project is to establish a monitoring system for DC stray current in the MTR railway system and to propose reduction measures.

The project shall:

  • Analyse the root causes of DC stray current;
  • Propose measures to reduce DC stray current with reference to international standards;
  • Develop an online continuous monitoring system for DC stray current and find out the key factors that affect railway safety; and
