Historically there have been many arguments between railways and other large companies such as
water authorities, gas suppliers and the post office, etc. concerning the interference from the
electrification with their enterprises. In such disputes the railways were always the target for the complaints.
Within the railways, signalling and telecommunication engineers have also had arguments with the traction people, but historically traction engineers have usually had the greater influence to the
detriment of the signalling and telecommunication systems.
What can the Signal Engineer do?
1. Understand the mechanics of the interference;
2. Explain to the project leaders the consequences of their choice;
3. Choose a system that is not affected by the interference.
