Introduction

The purpose of this document is to provide a methodology for the demonstration of electromagnetic compatibility (EMC) of rolling stock with 50 Hz single rail track circuits installed on Railtrack controlled infrastructure. It is based upon previously accepted safety assessments which were undertaken for Traction and Rolling Stock thereby allowing them to operate over 50 Hz single rail track circuits.

The methodology is split into two distinct parts - one which considers the effect of steady state electromagnetic interference (EMI), and the other which considers the effect of transient EMI on the 50 Hz single rail track circuits.
