50Hz AC Track Circuits

Introduction

Delegates attending this course will develop their skills and knowledge to conduct maintenance, faulting and testing activities on 50Hz AC track circuits efficiently and effectively. This course covers single rail and double rail 50Hz AC track circuits.

Objectives

On successful completion of the course the candidate will be able to:

Explain the operation and principles of single & double rail 50Hz AC track circuits
Identify the main components of 50Hz AC track circuit
Identify the different configurations of 50Hz AC track circuits
Identify 'Bonding Plan' symbols
Perform routine servicing of 50Hz AC track circuits in accordance with the current SMS and complete the relevant documentation
Use test equipment specific to 50Hz AC
Carry out a full test and interpret test results to identify possible faults at an early stage
Identify Infrastructure conditions that may effect correct operation of 50Hz AC track circuits
Carry out basic fault finding activities
Fault diagnosis and rectification to a 50Hz AC track circuit using a systematic approach
Determine whether a failure is ‘wrong-side’ or ‘right-side’
Locate and rectify faults
Replace specific items of 50Hz AC track circuit equipment

 Who Should Attend

Network Rail S&T Technicians and those who work within maintenance/installation teams who will be expected to maintain, test and/or commission 50Hz AC track circuits.

 Prerequisites

Candidates should have basic electrical/electronic knowledge and should have attended a Basic Signalling 1 course or equivalent

Features

Provides a comprehensive introduction to 50Hz AC track circuits and associated maintenance techniques. This course allows the candidate the opportunity for setting up and testing 50Hz AC track circuits in a safe environment on our fully operational track circuits (2 single rail circuits and 2 double rail circuits). This allows each candidate the chance to carry out full set up procedures, be able to take all the readings required to fully complete a record card and carry out basic fault finding techniques

Learning Approach

Classroom theory sessions using visual aids, practical demonstrations and practice with fault finding sessions. 

Assessment

2 part written test paper plus practical assessments (both of which must be passed to receive a certificate of merit)

Duration

5 + 1 days (5 days + 1 day re-call for practical assessments) 

Further courses

Support - one day refresher every 2 years (optional)

Number of Participants

Minimum 3            Maximum 5
