Track Circuit Bonding Design

Duration: 
5 Days
Location: 
At our training centre or on your premises by arrangement
Maximum number of delegates: 
10

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.

       

Key Features

Track Circuiting Concepts:

● Basic Track Circuit Operation
● Series and Parallel Bonding
● Permitted Spurs
● Electrical and Physical Stagger
● Double Rail, Single Rail and Common Rail Configurations
● 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

● 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

● Simple arrangements
● Full design from 1:100 plan

Assessment and Certification

The outcome of the course will be assessed by a written design assessment. Acheivement of the objectives will be confirmed by a certificate.

Pre-Requisites

The participant should already be familiar with signalling plans and basic signalling principles.
