Delegates who require an understanding of AC double rail and single rail Vane type track circuits.

By the end of this course successful delegates will be able to:

• Identify the main components of 50 Hz AC track circuits and their different configurations
• Understand the principles of double rail and single rail AC  track circuits
• Understand the principles of a Vane type relay
• Identify bonding plan symbols for AC track circuits 
• Replace specific items of 50Hz AC track circuit equipment
• Be capable of locating a basic fault and rectifying the fault
• Replace a specified item of the 50 Hz AC track circuit equipment 
• 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 including the phase angle meter
• Undertake track circuit testing as guided by Network Rail instructions
• Identify Infrastructure conditions that may affect correct operation of 50Hz AC track circuits 

40% classroom-based including PowerPoint presentations, proactive discussions, scenarios and diagrams/drawings.

60% practical-based on live AC single and double rail track circuits including taking readings from Vane type relays.

Theory and practical assessments will be undertaken to check the delegates' understanding and a certificate will be issued on successful completion of the course.

Delegates are expected to have a good understanding of the signalling industry and ideally have completed BS1/BS2 or equivalent.
