Signalling Design Courses

Duration	5 days
Location	Derby or at your venue
Delegates Maximum	6

Aim

This course will enable a signalling designer to progress to the production of track circuit bonding design for non-electrified and AC electrified lines.The participant should already be familiar with signalling plans and basic signalling principles.

Course Outcomes

Track Circuiting Concepts:

• Basic Track Circuit Operation
• Series and Parallel Bonding
• Permitted Spurs
• Electrical and Physical Stagger

• Fishplate Bonding, Jumper Bonding & Red Bonding
• Track Circuit Interrupters

External Factors Affecting Track Circuit Design

• Constraints on Joint Positions related to vehicle dimensions
• Constraints on Joint Positions imposed by track engineering
• AC Electrification Principles
• Traction Bonding Appreciation

Bonding Design Process (RT/E/S/1175 Train Detection)

• Constraints and Ground Rules
• Preparation
• Basic Arrangement
• Spurs from series bonded rails
• Parallel bonded rails
• Switches on parallel bonded rails
• Agree IRJ positions

Bonding Design Exercises
